The construction of roads can generate threats to the biodiversity of an important hydrological network made up of streams known as quebradas in the Peruvian Amazon. The objective of the study was to determine the composition, richness, abundance, diversity, dominance, and similarity of habitats of benthic macroinvertebrate communities of five streams located around the Iquitos-Nauta highway axis (Loreto, Peru). The collections were made in four periods (empty, dry, growing, and full), using a D-net type network. The benthic macroinvertebrate community was composed of 68 taxa and 4556 individuals, distributed in 4 phyla (Arthropoda, Annelida, Mollusca and Nematoda). The similarity analysis indicates that there were significant differences (p < 0.05) between the empty-dry seasons and the growing-full seasons; The dry season being the one with the greatest value of wealth, abundance, and diversity; and increasing the one with greater dominance. Chironomidae, Leptophlebiidae, Elmidae and Palaemonidae; were the most dominant taxa. The present work is a contribution to the knowledge of the macroinvertebrate communities that inhabit the small lotic ecosystems of the Peruvian lowland forest. [ABSTRACT FROM AUTHOR]

The impact of several pesticides on the diversity of arthropofauna associated with commercial potato cultivation was evaluated in Mollepata, province of Anta in Cusco-Peru, to determine which trophic guilds (TG) are affected. The treatments were fipronil, propineb and conventional (rotation of several pesticides). Thirty-five pitfall traps were placed in each treatment with the purpose of collecting the arthropofauna in potatoes. Five applications of the corresponding treatment were carried out and a total of five check-ups were carried out with a frequency of fourteen days. The most abundant families were Hemiptera: Cicadellidae (19.82%), Coleoptera: Chrysomelidae (16.33%) and Diptera: Sciaridae (11.92%). Propineb was the treatment that presented, at the family level, the largest total number of individuals. For the entire study, at the level of TG, the decreasing sequence of the total number of families was: phytophagous with 30 families (32.97%); predators 23 families (26.37%); detritivores 20 families (21.98%); parasitoids 10 families (9.89%); pollinators six families (6.59%) and finally omnivorous with two families (2.20%). Propineb presented the highest values of the total number of individuals in phytophages and parasitoids. On the other hand, alpha diversity indices did not present differences between treatments for omnivores, detritivores, pollinators and predators. The beta diversity indices were variable, generally obtaining greater similarity between the fipronil and conventional treatment. The phytophagous and parasitoid TGs were those that presented the most differentiated values when evaluating the effect of pesticides on soil arthropofauna based on alpha diversity indices.

Two new species of Neotropical aquatic beetles, Crenitulus namasus sp. n. from the Apurense plain and C. merida sp. n. from the Andes are described, both collected manually. Crenitulus namasus sp. n. is characterized by a minute body size, while C. merida sp. n. is characterized by its robustness. The main characteristic of the genus Crenitulus Winter, 1926 is evidenced in the body shape, which is wide in the humeral margin and attenuated towards the elytral apex, the antennae with nine antennomeres and the parameres pointed or attenuated towards the apex, in addition to presenting convexity in its outer margin. Based on a review of the species deposited in the Museum of Arthropods of the University of Zulia, Maracaibo, Venezuela, Crenitulus gamboa García, 2016 is synonymized with C. solstitialis Kirsch, 1873. Habitus, palps, antenna, mentum, prosternum, mesoventral process and genital sclerite are illustrated and a list with all recorded Crenitulus species is included. [ABSTRACT FROM AUTHOR]

Inside epiphytic bromeliads there is a variety of microhabitats and resources for arthropods, being important sites for biodiversity. In this work, the richness and diversity of arthropods associated with Tillandsia recurvata were determined in three locations from Tecozautla municipality, Hidalgo, Mexico. In the dry season, 112 specimens of T. recurvata were collected over plants (phorophyte) of the species: Acacia schaffneri, Myrtillocactus geometrizans, Bursera fagoroides, and Prosopis laevigata. Arthropods were extracted from each epiphyte and the morphospecies were identified to order and family; the richness, the diversity, and the expected number of species by phorophyte were calculated. The highest number of species corresponded to Araneae, Coleoptera, Hemiptera, and Diptera orders. Richness was higher on bromeliads whose phorophyte was P. laevigata while the diversity was greater when the phorophyte was M. geometrizans. The expected number of species was higher than that found in all phorophytes. The microenvironment of T. recurvata is favorable to arthropods to find refuge or to obtain food. The results set down the possible influence of phorophytes over the arthropods species in T. recurvata. [ABSTRACT FROM AUTHOR]

Toxicity of four pesticides in ecosystem services of terrestrial arthropofauna in cocoa cultivation was evaluated. Cypermethrin (T1), carbofuran (T2), copper oxychloride (T3) and chlorpyrifos (T4) were applied in a cocoa farm in San Martín, Peru. Forty pitfall traps were placed for each treatment to capture terrestrial arthropofauna in four evaluations. It is concluded that the families that presented the greatest abundance of individuals were Formicidae, Entomobryidae and Poduridae. For the global evaluation, significant differences were found in the predators for the specific richness index, being T3 the one that presented the lowest numbers; while for the Margalef index, the lowest value was T3. For the analysis by evaluations, significant differences were found in the detritivores during the second evaluation for the number of individuals, with T4 being the lowest number. Significant differences were also found in the predators during the first evaluation in the Margalef index, with the lowest value being observed in T4. The trophic guild that allowed the most efficient evaluation of the toxicity were the predators, T1 is the most compatible pesticide with the terrestrial arthropods associated with cocoa cultivation, and the alpha diversity indices showed significant differences between the applied pesticides.

In an article published in 1850, the German histologist and zoologist Franz von Leydig described cells in the mammalian testis, today know interstitial cells of Leydig, that were later shown to be the source of testosterone. He also gave the first description of the hair follicle bulge, and published numerous studies on invertebrates (worms, rotifers, arthropods, molluscs) and vertebrates (fishes, reptiles and amphibians). Leydig was the first to describe many new species including mites, snail and crabs. His name is also immortalized in the designation of several species including an annelid (Amphicaeta leydigi), a slug (Veronicella leydigi) and a water flea (Leydigia leydigi). Leydig published more than 200 scientific articles and eight books. His most important work was the book Lehrbuch der Histologie des Menschen und der Thiere (1857), that established him as the founder of comparative histology. He received many honours from scientific organizations worldwide. He died in his hometown Rothenburg ob der Tauber, at the aged 86 years. The foundations of histology were laid during this era, and Leydig was one of the pioneers in these developments. [ABSTRACT FROM AUTHOR]

The herbivory carried out by arthropods of the Curculionidae family on inflorescence of Espeletia killipii was determined experimentally through field and laboratory measurements. The samples of flowers were collected according to experimental design in two areas that present high and low anthropic alteration in the Tunjo river valley, into Chingaza Natural Park, jurisdiction of Calera-Cundinamarca. The insect feeds on the seeds causing a natural predation of this frailejon. The flowers were analyzed in the laboratory to quantify seed predation and the presence of the animal in its different stages of growth: larvae, pupae, worms and adults. The damage caused by the arthropod to the seeds of Espeletia killipii, added to the anthropogenic disturbances in the area and the increase in temperature due to climate change, can further alter the delicate balance of Espeletia killipii with the environment.

Arthropods are the richest group in diversity, and they provide great ecosystem services. However, they are traditionally considered as organisms that generate negative attitudes of rejection, fear, annoyance and contempt. These are due to cultural aspects, their own experiences or deformed representations in school. In this sense, this work seeks to identify the perceptions of a population sample of three levels of schooling in a public institution in the city of Armenia, and to carry out an intervention that orients positive attitudes and values towards their conservation.

The article focuses on the creation of hedges and creation of boundaries for fauna. Topics include an essential food source for red partridges, quail, curlews, little bustards, arthropods and many other species; the construction of the ridge to carry out with an agricultural tractor using a moldboard, or another specialized tool; and the construction of the ridge, accompanied by the planting of native species with high branches.

Three new species of Carabidae (Coleoptera) inhabiting highland grasslands and Chaco Serrano, in San Luis and Córdoba provinces of Argentina, are described and illustrated based on morphological external and genital characters. They constitute endemic species of different mountain systems. Two species belong to the genus Baripus Dejean, (B. (Baripus) merloensis n. sp. and B. (Baripus) puntano n. sp.), and one to the genus Cnemalobus Guérin-Ménéville, C. gustavoi n. sp. The new species are included in updated keys to the species of subgenus Baripus and genus Cnemalobus, respectively. Distributional data and habitat description are also provided. Finally, a quantitative panbiogeographic track analysis was performed including the subgenus Baripus, the Cnemalobus striatus species group, and other arthropod taxa belonging to biogeographic elements of gondwanan age. The resulting generalized track suggests that the peripampasic arc has different South American biogeographic elements that might have occupied it in different times. [ABSTRACT FROM AUTHOR]

The research was conducted in the tobacco farm "La Rosa" in the municipality of Pinar del Río, Cuba, with the objective of determining the diversity and abundance of predatory arthropods associated with arboreal species. A floristic inventory of the arboreal diversity was carried out to family and species level, and samples of the predatory arthropods were collected for their transfer and processing at the entomology laboratory of the University of Pinar del Río. Taxonomic keys were used to identify the arthropod species. Twelve tree species belonging to eleven botanical families were inventoried, with the greatest representation of fruit trees (58 %). The fourteen species of predatory arthropods identified presented regulatory activity on insects and/or mites, being pests on fruit trees, tobacco (Nicotiana tabacum L.), and other economically important crops. The most represented orders were Hemiptera, Diptera and Mesostigmata, while the families Coccinellidae and Phytoseiidae presented the highest species richness. It is also noteworthy that five groups of identified predators (phytoseiid mites, spiders, myrids, coccinellids, and syrphid flies) reached relative abundance ≥ 10 %. [ABSTRACT FROM AUTHOR]

To determine the incidence of pests on Tahiti lime grafted in six rootstocks, plots were established in three locations in Colombia. Samples of leaves and shoots were taken and the incidence of the main groups of arthropods was evaluated. During the samplings in Lebrija, Santander, the mite number / leaf of each species of mite was recorded by rootstock. Additionally, in two locations, the percentage of mite damage in fruits in harvest, and in one, the incidence of thrips in flowers were measured. In addition to descriptive statistics, non-parametric tests were performed, such as Kruskall Wallis to evaluate differences between rootstocks. The results show that there are no differences between rootstocks, except for: (1) The incidence of phytophagous mites in two samplings at the Caribia research center. (2) On the number of mites / leaves of Panonychus citri in Lebrija. It was found that there is no clear trend in favor of any genotype and the response to arthropods is dependent on the time of sampling. A list of insects and mites associated with Tahiti lime in the main production areas in Colombia and their natural enemies is presented. [ABSTRACT FROM AUTHOR]

The purpose of this research was to collect, codify and taxonomically identify the arthropod individuals found in 45 samples of three farms, under coffee cultivation, planted in organic, conventional and mixed system, in the municipality of Líbano (Tolima, Colombia) during 2014, in an investigation on the exergy. It was obtained that soil arthropods (including mulch and surface leaf litter) of the conventional farm (Type I) had a higher index of diversity than the organic farm and the latter had a higher index than the mixed farm. In spite of this, the organic farm has a greater population of arthropods that double the populations of Fincas Cafeteras Tolima INTRODUCCIÓN Este artículo se fundamenta en la evaluación de la diversidad de artrópodos en la zona cafetera de Colombia, Municipio del Líbano (Tolima) en tres diseños de producción de café con manejos agronómicos diferentes, y diferente estructura de agrobiodiversidad, en donde se realizó el cálculo de Índices de Diversidad aplicado a dichas poblaciones de Artrópodos (García A, 2016) en el marco de una herramienta de Termodinámica denominada Análisis Exer-goecológico (Szargut, Valero, Stanek, & Valero, 2005) En gran parte de las comunidades de pequeños campesinos cafeteros, la racionalidad de intervención del agroecosistema es inherente a su acervo cultural, por lo tanto, las tecnologías externas y la memoria biocultural convergen conventional farms and five times those of the mixed farm, which demonstrates the high interaction between arthropods and the dynamics of organic matter, in the role of transformation of lignocelulitic macromolecules and diversity residue, towards more mineralized forms and in search of the standard C / N ratio of nature.

The diversity of arthropods present in the crops of yellow and white Chrysanthemum morifolium Ramat. in greenhouse is analyzed, based on the species richness, abundance and trophic roles. The study was carried out in a greenhouse located in El Carmen (Jujuy). Field tasks consisted of three strokes per plant to 30 plants taken randomly, with two repetitions, and a specific sampling of extraction of five flowers in three opening states (floral bud, flower-semi-open and open flower) for each color throughout the crop cycle. Samples were observed under a stereoscopic microscope for the extraction of the associated arthropods, which were identified and stored in flasks with 70% ethanol as well as microscopy slides. A total of 9,027 arthropods were collected, distributed in the classes Insecta (eight orders and 25 families) and Arachnida (three orders and nine families). The most diverse functional group was the phytophagous. This included the dominant species Frankliniella occidentalis (Thysanoptera) and Tetranychus urticae (Prostigmata). The entomophagous group was represented by Anthocoridae (Hemiptera), Chrysopidae (Neuroptera) and 11 families of Hymenoptera parasitica, Phytoseiidae (Mesostigmata) and seven families of Araneae. The less abundant groups were the detritivores (Psocoptera), fungivores (Latridiidae), xylophagous (Bostrichidae), and the varied diet (Formicidae). [ABSTRACT FROM AUTHOR]

Thrips are small insects of the order Thysanoptera that usually feed sucking fluids of plants, fungi or arthropods (insects, mites). However, thrips occasionally can be a nuisance to humans. Thus, comments are presented and a scientific literature review is made about the relevance for public health of insects from the order Thysanoptera. [ABSTRACT FROM AUTHOR]

Baetidae is one of the most abundant and diverse families in the insect order Ephemeroptera. Among the baetid species distributed in Colombia (38 species and 9 genera), five are known to occur in the basin of La Vieja river, Alto Cauca (Andesiops peruvianus, Camelobaetidius edmunsi, Mayobaetis ellenae, Nanomis gallera, and Prebaetodes sitesi). Here, we estimate the species richness of Baetidae in La Vieja river based on specimens deposited in local museums. We examined 7226 baetid nymphs from 23 species in 11 genera collected in the La Vieja river. We found Baetodes and Camelobaetidius to be the richest genera (10 and three species, respectively), with Baetodes awa and Camelobaetidius edmunsi being the most abundant species in the river (3 563 and 1 282 individuals respectively). Here we present new registries for two genera (Cloeodes and Varipes) and eight species (Baetodes awa, Baetodes diasae, Baetodes pseudospinae, Camelobaetidius mathuriae, Camelobaetidius patricki, Nanomis rasmusseni, Prebaetodes meridinensis, and Zelusia principalis) in La Vieja river. Our richness estimates indicates that La Vieja river harbors around 61% of the baetid species described in Colombia (23 of the 38 species). [ABSTRACT FROM AUTHOR]

For 100 years, Biologia Centrali-Americana has been an important source of information for many groups of Mexican and Central American arthropods, and still remains a keystone for taxonomic work. However, many of the names included are now out of date. Here we provide an updated list of the species names of Diplopoda (millipedes) cited in Volume 14 of Biologia Centrali-Americana. MilliBase, a global taxonomic on-line database of the myriapod class Diplopoda, was used to update the names. The Diplopoda of Biologia Centrali-Americana included 205 names for 204 species and one subspecies (the subspecies was excluded here). Of those, 88 names were described as new in Pocock's work. Currently, 130 remain as valid names in the same genera, and 74 have been transferred to other genera. [ABSTRACT FROM AUTHOR]

The list of beetle species deposited at the Arhtropods Collection of the Facultad de Estudios Superiores Iztacala (CAFESI), UNAM, includes 10,277 specimens, grouped in five superfamilies, 15 families, 41 subfamilies, 172 genera and 570 species, of wich 231 are identified at species level and 339 at genus level and separated at morphspecies. The families Staphylinidae and Scarabaeidae represent 87.7% of the richness and 73% of the total specimens. The collection housed two holotypes of Paederinae and paratypes of three species of Paederinae and two species of Staphylininae (Staphylinidae). It has a regional geographic coverage, 96% of the species and specimens recorded come from nine states of south central region of México, mainly from Estado de México with 54.7% of the species and 41.6% of the specimens, followed by Morelos, Guerrero and Michoacán. The collection also includes 61 specimens of 11 species of Paederinae coming from Argentina, Bolivia and Brazil. Forty five percent of the species and 26% of the specimens come from the tropical deciduous forest, while 30.8% of the species and 17.6% of the specimens come from the temperate forest.

The objective of this study is to identify the arthropod species that causes seed loss during the pre-dispersal stage of Ramorinoa girolae Speg (chica), in Ischigualasto Provincial Park (San Juan province, Argentina). In January 2013, we randomly collected 10 fruits from the crown of 17 adult R. girolae trees found at three sites separated by approximately 4 km. Each fruit was kept in separate closed jars for 6 months, until the adult arthropods emerged. Different arthropod species were found to be associated with R. girolae fruit. Seed loss was caused by Anypsipyla univitella (Lepidoptera, Pyralidae), whose larva lives inside the fruit and can consume up to 4 seeds during its development. This larva causes up to 60% of seed loss during the pre-dispersal stage. A parasitoid of the genus Goniozus sp. (Himenoptera, Chrysidoidea, Bethylidae) was found in association with the arthropod in more than 65% of the cases. [ABSTRACT FROM AUTHOR]

The decomposition process and the composition of insects using biomodels of pigs were studied in the NE of Chubut province. The objective was to determine the species composition, abundance and richness of carrion arthropod fauna in the steppe environment. Seasonal surveys were performed for three consecutive years. Three domestic pigs were placed in wood cages with wire mesh in each experiment. Samples of arthropods from under, around and inside the corpse, were collected daily. We registered 36.157 individuals belonging to 78 species of 18 families distributed among the Diptera, Coleoptera and Hymenoptera orders. Three species of Calliphoridae are cited for the first time from Chubut: Paralucilia pseudolyrcea Mello, Paralucilia fulvinota Bigot and Chrysomya albiceps Wiedemann; and one species of Muscidae: Arthurella choelensis Patitucci & Mariluis. Sarcophaga (Lipoptilocnema) margaretae Lahille (Diptera: Sarcophagidae) is newly cited for the cadaveric fauna of Argentina. This is the first forensic entomology study carried out in Patagonia that allows to identify the decomposition processes and cadaveric fauna in this area. Therefore, it provides relevant information that can be used to solve human forensic cases in the region. [ABSTRACT FROM AUTHOR]

Sorghum (Sorghum bicolor (L.) Moench) during storage is infested by several insect species within which weevils mentioned as the most important. Because of this, the present study aimed to identify arthropods affecting sorghum seeds stored in the province of Villa Clara, Cuba. For which a diagnosis was made in the 13 municipalities of the province. In the execution of the state facilities and storage sites visited smallholders. Additionally were used historical records of incidents of insects intercepted in sorghum seeds in the period from 1991 to 2012. The information obtained allowed forming a database with the name, order, family, locality and year reported that each of the agencies. In Villa Clara were identified 11 species of arthropods incident on stored grain. Cheyletus malaccensis Oudemans (Trombidiformes: Cheyletidae) and Anisopteromalus calandrae Howard (Hymenoptera: Pteromalidae) were both beneficial species intercepted; Sitophilus oryzae L. whereas it was more often influenced in stored sorghum..

At present, Jatropha curcas Linnaeus constitutes one of the most studied plants worldwide due to its potential to produce oil, which can be transformed into biodiesel. However, there is not enough information yet about its ecological interactions with other plants and animals; for which the knowledge concerning the arthropods associated to J. curcas is an essential requisite for the adequate management of the crop. The objective of this paper is to present the results of a compilation made about these organisms (mainly insects, mites and spiders), to achieve a better exploitation of the plantations of this energy crop in Cuba. Within the group of plant-eaters, 151 insect species were found, among which two from order Hemiptera (Pachycoris klugii Burmeister (Scutelleridae) and Leptoglossus zonatus (Dallas)) stand out, in addition to four mite species. Among the beneficial ones, 90 insect, five mite and 13 predator spider species were found. Regarding pest management strategies, a higher emphasis is made on the chemical control measures and some cultural-type actions. Taking these antecedents into consideration, in Cuba it is essential to know the main organisms associated to this plant, in order to incorporate –with higher accuracy– the agroecological component in pest management, and thus contribute to the maintenance of the productive capacities of agroecosystems and their resilience.

Wolbachia infection is the most widespread in animals. Its ability to manipulate insect reproduction places It at the center of organismal biology, affecting such important processes like sex determination, cell cycle, generation and extinction of species and behaviour of arthropods, including several pest and disease vector insects. Attributes like vertical transmission, the speed at which it drives in the population, the ability to block the pathogenic activity of several microorganisms and the ability to shorten the lifespan of its host point to this bacterium as a potential tool to control harmful insects and nematodes. What are the possibilities offered by this pandemic? In the present work a detailed and updated review of the main aspects of this infection is presented, as well as the practical implications for managing pest and disease vector insects and nematodes. This review is based on the symposium of the same title held in the VIII Argentinean Meeting of Entomology. [ABSTRACT FROM AUTHOR]

Arthropods have been present in many expressions of Mayan culture, in this sense, the objective of this paper is an approach to the current knowledge we have of this group into three different zones of Yucatan (South, North Coast and East). To accomplish this purpose were used semi structured interviews concerning which arthropods were identified, how they could distinguish each other, which were considered harmful and which beneficial, if used for food and treatment, how this knowledge was transmitted and which variables influenced this transmission. They had extensive arthropods knowledge, resulted in the identification of more than thirteen orders. Knowledge was around species biology, of which they had some benefit (economic, therapeutic, or alimentary), those considered pests and even used to play with them. Knowledge and its transmission were influenced by variables such as economic activities performed, the age of the informants, migration and the use of the Mayan language. [ABSTRACT FROM AUTHOR]

The objective of this paper is to document and analyze the traditional knowledge about medicinal use of arthropods recorded in the Chilam Balam manuscripts of Chan Cah, Tekax and Nah and Ixil. The recipes that mention the use of arthropods were identified and a database was generated with the names of arthropods, their taxonomic identification, parts and products used, the illness and disease, and forms of preparations. Forty nine therapeutic recipes were analyzed in the Chilam Balam manuscripts: 21of Ixil, 20 of Tekax and Nah, and 8 of Chan Cah, where it cited the use of 13 arthropods to cure 39 illness or diseases and mentions the use of four parts of the arthropods: oil, guts, body and stinger; three products: wax, honey, venom and the larval phase and honeycomb of bees and nest wasps. The results of this research highlight the fact that, while the resources herbalists are the elements most studied in the preparation of therapeutic treatments, there is a diverse knowledge about the medicinal use of faunal resources and arthropods in particular, which were recorded in the recipes of Chilam Balam manuscripts: Chan Cah, Tekax and Nah and Ixil. We suggest continuing the study of medicinal fauna registered in the manuscript of Colonial Maya, and the analysis of medicinal properties of the arthropods, in addition to conducting research on the current knowledge that Yucatan Peninsula communities have about this group of fauna.

Arthropods, since prehispanic times, was been of great importance among the Mesoamerican peoples, both because of its biological characteristics and its cultural impact. Indigenous groups have generated a deep and systematic knowledge about the different arthropods that are distributed in our country, which is reflected in the use of these organisms for feeding and medicinal use, mainly. There are only a few studies of zootherapy on prehispanic and colonial sources, but this documents represents a vast body of ancient and traditional knowledge about nature, so it is necessary to carry out scientific studies about these muniment in order to understand the knowledge and use of resources involved in the processes of health and disease among people Nahua prehispanic and contemporary. This work aims to identify the arthropods as medicinal resource that are reported in the Florentine Codex, Libellus of Medicinalibus Indorum Herbis and Historia Natural de Nueva España. Such works were consulted and were extracted his texts in spanish which mentions the arthropods useful in Nahua medicine; biological works were reviewed and listed on such taxonomic sources. Eleven arthropods were reported in this study, belonging to fourteen taxonomic orders, to cure 35 diseases. Despite the scant mention of this faunal group in these sources, it is important to record the different uses of these organisms that were part of the biocultural heritage of the Nahua people. It is essential to realize further studies and comparisons between more sources, as this will allow to understand some of the current uses that are still being given to animals in mexican traditional medicine, particularly with arthropods.

The records and the knowledge of Lepidoptera larvae associated with weedy plants generate valuable and new information for this group within agroecosystems towards an integrated weed management program and a better understanding of arthropod fauna associated to these plants. Throughout 2008-2009, several Lepidoptera larvae were found in weed samples collected in the Caribbean of Costa Rica within banana farms and neighboring areas. These samples were identified with avalaible literature and a larvae collection of one of the authors. The records of 25 specimens from six Lepidopteran families on 13 weed families are presented in this paper, some of them are interesting in terms of biological control. [ABSTRACT FROM AUTHOR]

Invertivores fishes are an important component of neotropical streams and they represent a link between aquatic invertebrates and piscivorous species. This study evaluated the breadth diet and interspecific food overlap of nine invertivores fish species during three consecutive hydrological phases: falling (December/07, January/08, February/08 and March/08), low (April/08) and rising waters (June/08), in two sections of a Venezuelan neotropical stream, which were located at different elevation, high watershed (HW) and low watershed (LW). The fishes were collected with a beach seine (5mm mesh) between 8:00 and 11:00 hours. The diet of each species was evaluated using an index of relative importance (IRI), which includes as variables the number, weight and occurrence frequency of food items consumed. The Levin' index (B i) and Morisita (IM) were used to estimate the breadth diet and interspecific food overlap, respectively. All estimations were made using the numeric proportion of preys. Nine fish species were captured, eight Characiformes, of which three were captured in HW (Knodus deuteronoides, Creagrutus bolivari and C. melasma) and five in LW (Thoracocharax stellatus, Moenkhausia lepidura, Cheirodon pulcher, Ctenobrycon spilurus and Aphyocharax alburnus), and one Cyprinodontiformes (Poecilia reticulata), which was also found in HW. In HW aquatic insects were the main resource consumed by fishes while plant material and terrestrial arthropods were secondary resources. In LW the fishes ingested all of these items in addition to zooplankton (Copepoda, Cladocera and larval stages of Decapoda). However, there was a temporal replacement with a predominance of zooplankton in falling and low water. In general, the breadth diet decreased during the falling water in both sections and increased in rising water. However, the average breadth diet was higher in HW. The interspecific food overlap was high in HW while low values were more frequent in LW and its temporal variation was opposed in both sections during almost all the sampling period. Rev. Biol.

La investigación se condujo para evaluar la presencia y los daños provocados por los fitófagos asociados a los pastos elefante enano (Pennisetum purpureum vc. Mott) y hierba de Guatemala (Tripsacum laxum Nash). Se utilizaron métodos no paramétricos en el análisis de los datos. Durante los dos primeros años (2006 y 2007) no se evidenciaron diferencias entre los pastos, en cuanto a los insectos-plaga presentes. Sin embargo, en el año 2008 sí difirieron, con una proporción superior (P < 0.05) para Pennisetum con respecto al Tripsacum. Los dípteros resultaron de mayor proporción (P < 0.001) en 2007 y 2008, diferenciándose del resto de los fitófagos. Entre los fitófagos más frecuentes en los pastos estudiados estuvieron los crisomélidos: Epitrix sp. y Centrinaspis penicellus, el saltahojas: Hortensia similis y los hemípteros: Zicca taeniola y Jalysus reductus. No se presentaron diferencias entre los biorreguladores. Los más frecuentes fueron las arañas y hormigas, la tijereta (Doru taeniatum), sírfidos, la chinche asesina (Zelus longipes), el coccinélido (Diomus bruneri) y la santanilla (Wasmannia auropunctata). La época resultó no significativa en ambos pastos durante el 2006. Igualmente fue para el Tripsacum durante el 2008. Sin embargo, el 2007 resultó ser significativo para ambos pastos, con una proporción mayor a favor de la época de lluvia (P < 0.01). Este comportamiento se repitió en el 2008, solo para Mott, cuyos resultados se relacionan con el comportamiento de los factores climáticos. Se concluye que los pastos Mott y Tripsacum mostraron resistencia ante el ataque de organismos nocivos, fundamentalmente de insectos masticadores, al mostrar muy pocos daños visibles durante las evaluaciones. Se recomienda continuar los estudios de los insectos-plaga asociados al cultivo y su comportamiento en los diferentes meses del año. [ABSTRACT FROM AUTHOR]
