The search for insecticidal plant compounds is one of the strategies for the control of species such as Spodoptera frigiperda, a polyphagous species considered a sporadic pest of important crops. The objective of this work was to evaluate the biocidal effect of Melia azedarach (Meliaceae) leaf and seed extracts on S. frugiperda (Lepidoptera: Noctuidae) larvae, assuming that the higher the dose, the higher the percentage of larval mortality. The design used was completely randomized, with four (4) treatments and ten (10) replicates, applied to second instar larvae. The results showed that the T4 treatment dose (30%P/V) of leaf extract was the most effective, presenting 100% of dead larvae 6 minutes after the treatment was applied, compared to the control treatment (0%P/V). Similarly, the T4 treatment (30%P/V) of the seed extract obtained 100% mortality of larvae at 8 minutes of exposure, compared to the control treatment. However, M. azedarach leaf extract has a greater biocidal effect than seed extract on S. frugiperda larvae. In conclusion, M. azedarach can be incorporated into control programs for this pest.

The genus Athetis Hübner (Lepidoptera. Noctuidae. Amphipyrinae) comprises numerous species worldwide, two of them recently reported as pests of maize in China. This work presents the first record of an Athetis species feeding on soybean in the eastern region of the province of Córdoba, Argentina. The specimens were identified as Athetis rionegrensis status rev. based on external morphology and genitalia characters for both sexes. Furthermore, additional specimens were collected in the province of La Pampa, Argentina, on October, 2021.This species was only known to be in Alto Valle, province of Río Negro, Argentina, therefore these specimens represent the first record of the species outside that province. The correct assignment of this species to the Athetis genus is confirmed. Finally, the implications of this new record are discussed. [ABSTRACT FROM AUTHOR]

In the present work, aspects of the duration of the embryonic and larval development of the granulated cutworm Feltia subterranea Fabricius are described. The first generation of larvae was found feeding on tomato seedlings (Solanum lycopersicum L.) at the "Las Piedras" farm in Guanabacoa, Havana, Cuba, in October 2017. For the insect rearing, larvae were transferred to the Entomology-Acarology laboratory of the National Center of Animal and Plant Health (CENSA). They were kept independently in mesh cages, and tomato seedlings of the angean variety were used for their feeding until the end of that phase. In the adult phase, females and males were independently mated and observed daily to determine the time that oviposition occurred and duration of this phase. Eggs deposited on the same day were used to determine the time taken by embryonic development, duration of the larval stage, and the number of larval stages. Embryonic development took 4 days. The eggs were always deposited in clusters on young plant leaves. The insect presented six larval stages and the larval period lasted 15 days. A gregarious behavior, more marked during the first instars, was observed during the larval phase. [ABSTRACT FROM AUTHOR]

The present study was performed with the objective of determining whether the density of cutworms is affected by the type of predecessor crop and field environment. The effect of each particular predecessor crop was assayed on three paddocks selected in 2014 and another three in 2015. The evaluations were done on stubble from the following grain crops: earlysown soybean (ES), latesown soybean (LS), sunflower (S) and maize (M). Sampling was performed at both lowground and highground sites in each paddock for determination of the density of cutworms on five and ten 1 m2 subsamples collected in 2014 and 2015, respectively. Thirty cutworms were bred to adulthood each year for their identification. Such experimental assessment showed that Agrotis robusta was the predominant species. Analysis of variance for density of cutworms was performed following a factorial design considering predecessor crop, paddock environment and year as treatments. The three of these factors affected the density of cutworms and did not show interactions with each other. Observed density values of cutworms were 0.17, 0.4, 1.7 and 2.88 m-2 in M, S, LS and ES stubbles, respectively. Cutworm density was higher in 2014 and for lowground sites. These results allow the identification of predecessor crops and field environments holding different risk of damage by cutworms, contributing in that way to the development of more efficient sampling protocols and the integrated management for that kind of plague.

The transgenic maize that expresses the Bt protein is one of the strategies most used for the control of Spodoptera frugiperda, key pests of this crop in America. With the objective of verifying the susceptibility of S. frugiperda; toxicity studies were conducted of the proteins Bt expressed in leaves of different events of maize released in Paraguay, 2B587hx™ (cry1F); VT triple PRO™ (Cry1A/Cry2Ab/Cry3Bb) and Formula TL™ (Cry1Ab). The rearing of S. frugiperda was conducted in the laboratory to obtain a uniform population under controlled conditions of temperature (25 ± 2 °C), relative humidity (60 ± 10%) and photoperiod of 14:10 h (L:D). Mortality was evaluated and in the case of survivors; the weight and length of the pupae, the fertility of the females, the longevity of the adults, the viability of eggs, and the duration of the different stages and the total cycle. The supply of larvae neonates in the leaves of maize of the event VT triple PRO™ produced 100% mortality; however, in the larvae fed with leaves of the events 2B587hx™ and Formula TL™; the mortality was 58% and 56%, respectively. The survivors to these treatments had a longer life cycle, fertility and reduced fertility. [ABSTRACT FROM AUTHOR]

Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) is a moth that has genetically diverged in two strains named "corn" and "rice." This study was focused on carrying out a molecular characterization of the species with Amplified Fragment Length Polymorphism (AFLP) using larvae collected in the departments of Córdoba (North), Meta (East), and Valle del Cauca (West) in corn, cotton, and rice fields, to improve the information of the species obtained in 2008. In this work, 134 DNA extractions were made from each larva head and 45 samples were amplified with three combinations of AFLP primers that produced 101 loci. The AFLP were useful to determine that populations of S. frugiperda of Colombia have a high genetic variability, but they do not differentiate the strains as other authors reported. The analysis of molecular variance (AMOVA) showed that populations of S. frugiperda from the three departments were not genetically differentiated. The UPGMA dendrogram obtained also showed that there is no a genetic differentiation of the genotyped individuals based on the geographical location or the crop sampled. Our results coincide with a previous report obtained with the same species of Colombia based on a sequence of the mitochondrial gene cytochrome oxidase I (COI). [ABSTRACT FROM AUTHOR]

The direct sow of onion to obtained of bulb is attacked annually in Banao, Sancti Spíritus, Cuba, by Spodoptera exigua Hübner. A survey to the farmer that cultivated onion was carried out between November 2004 to June 2005, to evaluate the behavior of the insect by means of a scale of grades to determine the incidence and intensity of damage and the influence that other factors: control type, conservation of soil, dispersion of crop areas, boundary with affected areas, weed management, association with other crops, and disposition of furrow. With the 133 observations establishment non parametric correlations settled down Spearman and Kendall's NS 0,05 between damage and supposedly influential factors; the strongest interactions were located in the factors disposition of the furrow and weed management; and the grade of soil conservation. The test of Mann-Whitney indicated highly significant relationship among the variables: weed management (clean soil and with weed) and furrow disposition (in slope and contour); only significant in control type (chemical and not chemical) and soil conservation (degraded and conserved).

Laboratory bioassays were conducted to evaluate mortality and development of the corn earworm, Helicoverpa zea (Boddie), fed on meridic diet with different incorporated concentrations of the Cry1Ac endotoxin of Bacillus thuringiensis. The basic insect colony was obtained from maize of the Colombian "Piedemonte" eastern plains. LC50 calculated by Probit analysis seven days after starting the experiments with neonate larvae, varied from 3.45 to 6.12 and LC80 from 7.12 to 10 μg/ml. Toxin concentration had a marked influence on larval and pupal development, expressed as weight decrease as toxin concentration increased in the diet. Concentrations near or higher than 1.0 ppm caused high larval mortality and a high percent of deformed pupae. No significant difference between the weights obtained with low dosages and the check was obtained. However, a significant increase of the developmental time of both stages was observed when larvae were fed on diet with concentrations higher than 0.01 μg/ml, meaning a longer feeding period and fever annual generations of this polyphagous insect. It is considered that these basic data represent valuable information on the developmental responses of the insect exposed to transgenic cotton and corn, expressing the Cry1Ac toxin.

Sunflower (Helianthus annuus) is an oilseed crop pollinated by Apis mellifera L. and other diurnal bees in different regions of the world. However, their flowers are also visited by insects active at night. During three agricultural years, the diversity of nocturnal visitors to sunflower heads was assessed in five different sites in Argentina. The foraging behavior of the main visitors as well as the stigmatic receptivity variations along the day were also studied in order to determine whether or not these visitors contribute to pollination. At least 67 species or morpho-species belonging to four nocturnal visitor orders were recorded. The richest and most abundant order was Lepidoptera (44 species or morpho-species, five families), followed by Coleóptera (18 species or morpho-species, nine families), Orthoptera (three morpho-species, one family) and Blattaria (two species, one family). Lepidopterans foraged exclusively for nectar while species in other orders consumed pollen and/or floral parts. However, stigma receptivity was greater during the day, peaking at midday (12:00 - 14:00). Unexpectedly, moth species widely outnumbered bee species as sunflower visitors. Since moths potentially transfer pollen at a time of the day when stigmas are least receptive, it is unlikely that they do effectively pollinate sunflowers. [ABSTRACT FROM AUTHOR]

Graptocullia Köhler from Argentina is redescribed. Two species are recognized in the genus: G. sagittata Köhler, 1951 and G. xylinoides (Köhler, 1951) comb. nov. The two species are briefly redescribed and differences are discussed; adults, and both male and female genitalia, are illustrated. The following generic change is proposed: Riagria Köhler, 1951, is placed as a junior subjective synonym of Graptocullia Köhler, 1951. Lectotypes are designated for both species.

In the course of searching for plant chemicals with potential insecticide properties, the activity of Melia azedarach L. senescent leaf and ripe fruit extracts (2, 5 and 10%) was evaluated on larvae of Spadoptera eridania Cramer (Lepidoptera: Noctuidae). This polyphagous species is considered a sporadic pest on many important crops. Food consumption was assessed and an antifeedant index was calculated through choice tests. Also, food consumption, larval mortality, weight and depositions were recorded and nutritional indices were calculated in-choice tests. Results from choice tests showed a strong antifeedant effect of both extracts. In no-choice tests, the leaf and fruit extracts strongly reduced food consumption and larval weight, except with fruit extract at the lowest concentration. Larvae did not reach the pupal stage when high concentrations of leaf or fruit extract were used. Antifeedant activity was corroborated by nutritional indices, which also revealed negative effects of extracts on relative consumption, growth rates and efficiency in utilization of ingested and digested food, although digestibility was not affected. Our results suggest that M. azedarach extracts could be incorporated in management programs for this insect pest. [ABSTRACT FROM AUTHOR]

One of the plagues intercepted by the Health's supervisory Service of Animals and Plants (APHIS) of United States in the exports of some species of flowers of court of Colombia is Copitarsia spp. The present study evaluated the evasive answer of Copitarsia decolora (Lepidoptera: Noctuidae) by means of the simulation of calls of echo-location of bats as a proposal for the handling of flowers in post-harvest rooms, under controlled conditions. The shapes of the signs of echo-location of the bats were taken from some samples of insectivorous quirópteros and were simulated by means of the software "Sound Ruler", determining the fundamental parameters that characterize the calls, such as their width, frequency and forms, among others; starting from this characterization, an electronic system was designed and built to reproduce the echo-location calls. The system was tried, emitting the reproduced signal toward a sample of Copitarsia, and an evasive reaction was observed as result of this signal. [ABSTRACT FROM AUTHOR]

The cutworms complex in the semiarid oriental region of La Pampa province is integrated for: Agrotis malefida, A. gypaetina, Peridroma saucia y Pseudoleucania bilitura (Lepidoptera: Noctuidae). The present contribution is a synthesis of the available information on these four species that cause damages in the cultures. The group of the noctuidos is described and the biology is synthesized with special reference to the species mentioned previously. Also, for each one of the species it is provided the geographical distribution and a listing of host plants. The complex includes three neotropicales species (A. malefida, A. gypaetina and Pseudoleucania bilitura)', the distribution of the first one extends until the South of Neartida and a cosmopolitan species (Peridroma saucia). The information is emphasized taken place on the group in Argentina. [ABSTRACT FROM AUTHOR]

The aim of this study was to investigate the presence of larvae of cutworms, identify the species in which they belonged, and establish which was their active period in pastures of alfalfa (Medicago sativa L.) in two different subregions of the Eastern physiographic area of La Pampa Province in Argentina. Samplings were carried out during years 2001 and 2002 in the districts of Maracó, "Trenel, and Capital.T wo plots of alfalfa were revised each year. Five stations were delimited in each plot and 20 to 40 plants were selected in each station and in them the crown, the adjacent litter and the first five centimetres depth of soil were revised. Larvae of cutworms were collected manually and identified in the lab. They were keep in a breeding box, with artificial diet until adult emergence. Results suggest that the cutworms complex includes four species of Noctuidae, i.e., Agrotis gypaetina Guenée, Agrotis malefida Guenée, Pendroma saucia (Hüber) and Euxoa bilitura Guenée. The two last species were sporadicly recorded and in low density whereas the two first species were most abundant, detected from July-August, when they had reached 2 mm long and by the end of October they measured 40 -- 45 mm long. The active period of the larva -- i.e., when they feed and thus can damage crops -- was August to November. [ABSTRACT FROM AUTHOR]
