- Abstract
Biological control using predatory mites is an important component of pest management in a wide range of crops, including grapes. However, the trophic relationships established in these environments are still not fully understood. The use of molecular tools can contribute to identify the food sources of predatory mites and disentangle the complex relationships occurring in the field. We hypothesized that using qPCR and TaqMan probes we could quantify the proportion of plant based food sources and animal diet of various predatory mites throughout the season. Hence, our specific objectives were: 1) to design speciesspecific primers and TaqMan probes to identify the main mite groups in vineyards from La Rioja DOC Region (northern Spain), 2) to detect prey and plant products in predatory mites via PCR and qPCR, and 3) to validate these methods using predatory mites collected from the field. First, we designed specific primersprobe sets to identify the main predatory mite species in the region (Typhlodromus pyri and Kampimodromus aberrans) as well as to detect their potential prey (e.g. tetranychiids, tydeiids and eriophyid mites) and plant food sources. Then, we developed a predator-prey system (T. pyri and Tetranychus urticae) to quantify DNA by qPCR and establish post-consumption detection times of plant and animal food sources. Third, we collected predatory mites from the vineyard to unravel their prey items and establish their trophic interactions. Ultimately, detecting food sources within predatory mites could provide a useful tool to better understand the effectiveness of biological control using predatory mites in vineyards more...

- Abstract
Viticulture is a valuable sector worldwide with an extraordinary socio-economic impact in Spain. Numerous pests and diseases threaten vineyards, and their management primarily relies on the use of conventional agrochemicals. The current paradigm of sustainability pursues the implementation of ecologically sound strategies in vineyard ecosystems. The use of cover crops is arising as an alternative with numerous benefits, including favoring above-belowground biodiversity and the presence of beneficial soil organisms such as the entomopathogenic nematodes (EPNs). We hypothesized that the use of specific cover crops in vineyards might enhance the natural occurrence and activity of EPNs by modulating the assemblage with associated organisms. We performed the experiments in an ongoing experimental vineyard (Vitis vinifera var Tempranillo, clon RJ-26, rootstock ‘110-Richter’) located in Logroño (Spain), drove with different soil management systems (three replicates each): conventional tillage practice and the cover crops (i) seeded with Bromus catharticus (Poaceae), (ii) flower-driven, and (iii) spontaneous. We took four soil composite samples per plot (n = 48 per sampling time) late spring and early autumn in two consecutive years (2017 and 2018). By using species-specific primers/probes qPCR sets, we screened for the presence and abundance of eight EPNs species and 12 related soil organisms: six nematophagous fungi, four free-living nematodes, and two ectoparasitic bacteria. Additionally, we assessed the EPN activity by the traditional insect-bait method. Overall, we recorded higher EPN numbers or activity rates on cover crops than on bare soils. However, some of the results were divergent among no-till treatments. We observed not only higher EPN abundance and activity on spontaneous covers but lower numbers of antagonistic organisms, particularly endoparasitic nematophagous fungi. Thus, according to our results, the use of spontaneous covers could be the most promising more...

Most predatory mites belong to the family Phytoseiidae (Acari). Throughout the world, phytoseiids are involved in the biological control of phytophagous mites in vineyards. Conservative strategies, including cover-vegetation management, are essential to achieve environmentally friendly viticulture. The abundance and diversity of phytoseiid mites in the grapevine canopy and the vegetal ground cover of a Mediterranean vineyard were surveyed by weekly samplings, from early May until the end of September for two years (2016 and 2017). Three types of soil management without herbicide application were analysed and referred to as >Tillage>, >Spontaneous Cover>, and >Flower-driven Cover> treatments. Six phytoseiid species were collected on the grapevine canopy, with Typhlodromus pyri being the dominant species (99.5 %). Five phytoseiid species were recorded in the ground cover, with Typhlodromus and Neoseiulus as the major genera. The Flower-driven Cover treatment showed the highest abundance of phytoseiids in the grapevine canopy. However, both species richness and abundance of phytoseiid mites on the ground-cover vegetation were highest in the Spontaneous Cover treatment. These observations suggest that improving vegetation cover would promote both the abundance and diversity of phytoseiid mites in vineyards because the greater supply of pollen would enhance their survival. Therefore, the use of cover crops in vineyards represents a means of improving vineyard ecosystems by conservative biological control., This study was grant supported by the Ministry of Economy and Competitiveness (AGL2014-53336R). MGSR and AVB were supported by a fellowship from the University of La Rioja (Spain) (FPI-UR 2015 and 2018, respectively) more...

- Abstract
Conservative techniques, such as ground cover management, could help promote viticulture sustainability, which is a goal of conservation biological control, by providing shelter and food sources for predatory insects. A field experiment was conducted in a Mediterranean vineyard to evaluate ground cover management impacts on predatory insect and potential grapevine pest abundance and diversity, both on the ground and in the grapevine canopy. Three different ground cover management techniques (tillage, spontaneous cover and flower-driven cover) were tested for two years (2016 and 2017). Overall, the ground cover management significantly affected the abundance of important epigeal predators, of which carabids, forficulids and staphylinids were the most captured. The carabid abundances under both the cover crop treatments were found to be approximately three times higher compared with that under the tillage treatment. In contrast, the canopy insect abundance in the vineyard was similar among the treatments for both the predators and the potential grapevine pest species. These results indicate that cover crop vegetation can be used in vineyards to enhance predatory insect abundance and may improve agroecosystem resilience more...

- Abstract
Sustainable agriculture requires the support of new tools for successful and low-impact management of pests and diseases at global and local scales. The implementation of cover crops is considered a promising alternative ecological structure for sustainable agriculture, because they provide refuge to natural enemies of pests. Specifically, we hypothesised that implementing cover crop vegetation in a vineyard can enhance populations of natural enemies as a measure to support conservation biological control. We analysed insect abundance and diversity on Vitis vinifera var. Tempranillo (clon RJ-26, rootstock “110-Richter”) in a Mediterranean vineyard located in La Rioja, Spain from spring to autumn 2016–2017. Two types of sampling systems (pitfall traps and vacuum sampling) were used in each of the three evaluated ground cover management approaches (n = 3): (i) tillage, (ii) spontaneous cover, and (iii) flower-driven cover. A total of 58 families that belonged to four functional subgroups of insects (predators, parasitoids, phytophagous insects, and pollinators) were found. Overall, differences among the three treatments were only detected for total abundance of insects collected in the ground traps, and the “spontaneous cover” treatment showed significantly higher predator richness and abundance. However, the higher Shannon–Wiener value was recorded for “flower-driven cover” at both the ground and canopy levels. In addition, the abundance of predators, parasitoids and phytophagous insects in the ground traps for both cover crop treatments was more than two times higher than that observed in “tillage” treatment. Several predator taxa, such as ants, ground beetles, earwigs, and vespoid wasps had significantly higher representation under spontaneous cover treatment. Moreover, for parasitoids, the “flower-driven cover” treatment revealed higher Hill numbers values (0D, 1D, and 2D) at the canopy level, although no significant differences were observed. These results indica more...

- Abstract
Trabajo presentado en el International Congress of Grapevine and Wine Sciences, celebrado en Logroño (España), del 7 al 9 de noviembre de 2018, Viticulture is a worldwide valuable sector, with special relevance in Spain for their socio-economic impact. Vineyards are threatened by numerous pests and diseases, and their management relies primarily on use of conventional agrochemicals. Current paradigm of sustainability pursues the implementation of ecologically sound strategies. The use of cover crops is arising as an alternative with numerous benefits, including favouring above-belowground biodiversity. We hypothesize that vineyard with cover crops might increase the prevalence of entomopathogenic nematodes (EPNs), biocontrol agents of soil pests, modulating the assemblage of other associated organisms. The presence and activity of native EPNs were evaluated in an ongoing experiment in La Grajera (Logroño, Spain) on Vitis vinifera var Tempranillo (clon RJ-26, rootstock “110-Richter”) investigating tillage, and three types of covers: spontaneous, flower-driven, and seeded with Bromus perenne (Poaceae) (n = 3 per treatment). During late-spring and early-autumn 2017, 48 composite soil samples (12 cores, 2.5 cm diam X 20 cm depth) were taken to ensure balanced spatial distribution (two pair’s rows/inter-rows per plot). Each sample was assessed for the presence and abundance of 9 EPNs and other related organisms: 6 nematophagous fungi, 5 free-living nematodes (FLNs), and 2 ectoparasitic bacteria, by qPCR approaches. Moreover, traditional insect-bait provided the measurement of EPN activity. In spring 2017, nematode activity was slightly higher (P = 0.068) in inter-rows than in rows. However, this trend was only observed for the tillage and seeded treatments in later autumn (P < 0.05). Two EPN species were isolated: Steinernema feltiae and, for the first time in La Rioja, Heterorhabditis bacteriophora. The insect-baits detected low EPN-FLN incidence in the isolates, indicating that EPNs could suffer low competition with other nematodes for the cadaver under this scenario. The ongoing surveys in 2018 will supply additional data on their natural distribution and assemblage. more...

- Abstract
Tetranychus urticae es un ácaro cosmopolita y polífago que causa problemas en más de 150 cultivos de importancia económica, constituyéndose en su principal plaga en muchas ocasiones. Por su parte, Panonychus ulmi también es una especie ampliamente distribuida y polífaga que alcanza su mayor importancia como plaga de frutales de hoja caduca y, en particular, en el cultivo del manzano. Los ácaros plaga han incrementado notablemente su importancia, entre otros motivos, por el uso indiscriminado y masivo de productos fitosanitarios orgánicos de síntesis poco selectivos que han mermado de forma drástica las poblaciones de sus enemigos naturales. Ello, unido a la facilidad que sus poblaciones tienen para adquirir resistencias frente a productos fitosanitarios, ha hecho que, en la actualidad, ocupen un primer plano en la problemática fitosanitaria general. Considerando, además, la importancia de actuar dentro del Manejo Integrado de Plagas (IPM), resulta de especial interés desarrollar investigaciones que tenga como objetivo optimizar su puesta en práctica en el caso de las plagas de ácaros. En el presente estudio, y respecto a T. urticae, se ha trabajado en dicho objetivo en dos sentidos. Por un lado, se ha analizado con detalle el efecto que dos plaguicidas biorracionales (el inhibidor de la síntesis de quitina, flufenoxurón, y el antagonista de la ecdisona, azadiractina) tienen sobre la plaga y, por otro, se ha analizado la compatibilidad de la utilización de cada uno de ellos con el hongo entomopatógeno Beauveria bassiana. El flufenoxurón mostró una importante eficacia acaricida sobre huevos, protoninfas, deutoninfas y adultos de T. urticae, eficacia que resultó ser especialmente importante en el caso de las protoninfas. Por su parte, la azadiractina también mostró un efecto interesante sobre los mismos estados y estadios de desarrollo del ácaro (más importante sobre protoninfas y deutoninfas), aunque menor que el del flufenoxurón. El efecto de los acaricidas aplicados sobre hembras adultas fue diferente entre ellos. Así, mientras que el flufenoxurón no afectó ni a la longevidad ni a la fecundidad y sí a la fertilidad y a la supervivencia de su progenie, la azadiractina tuvo un comportamiento opuesto, afectando solo a la longevidad y a la fecundidad. Muy interesante resulta conocer el efecto que los productos fitosanitarios ejercen sobre los parámetros de la tabla de vida de poblaciones de las plagas en unas condiciones físicas concretas. En el presente trabajo, se determinó que, en las condiciones ensayadas, el flufenoxurón redujo de forma significativa la tasa intrínseca de crecimiento (rm) de T. urticae a la concentración de 2 mg/l, de modo que, a dicha concentración, la población del ácaro tendió a aumentar pero de forma extremadamente lenta (con un tiempo de duplicación de más de 2.200 días). De forma similar, la azadiractina provocó un descenso drástico en la rm del ácaro cuando se aplicó sobre hembras jóvenes a la concentración de 80 mg/l. De hecho, el valor de dicha tasa intrínseca de crecimiento pasó a ser negativa, indicando que la población así tratada tendía a desaparecer (reduciéndose a la mitad cada 21 días). Generar conocimientos que contribuyan a compatibilizar el uso conjunto de la lucha química y la lucha microbiológica tiene una importancia obvia en el contexto del IPM. Así, en el presente trabajo, se demostró que el flufenoxurón no afectó al crecimiento del micelio de B. bassiana. Además, resultó que la aplicación conjunta sobre T. urticae del compuesto químico y del hongo entomopatógeno tuvo un efecto sinergista. Por su parte, aunque la presencia de azadiractina en el medio de cultivo sí redujo el crecimiento de micelio del hongo, cuando se aplicaron conjuntamente sobre el ácaro, también se observó un efecto sinergista, aunque menos acusado que en el caso del flufenoxuron. En lo que se refiere a P. ulmi, las investigaciones se centraron en la mejora de su cría y en la posibilidad de disponer de individuos en laboratorio, como base para facilitar las investigaciones sobre el ácaro. También se enfocó el interés en la determinación de la salida de la diapausa por parte de los huevos hibernantes y en la modelización del desarrollo embrionario postdiapausa, para poder predecir la fecha de eclosión en campo, todo ello, para ser utilizado como herramienta en la toma de decisiones dentro del manejo de la plaga. En concreto, se evaluó la calidad como huéspedes, de 12 especies leñosas. Se observó que el huésped utilizado influyó de modo importante en diferentes parámetros biológicos de las hembras adultas de P. ulmi y sobre los parámetros de la tabla de vida. Así, se observaron diferencias importantes entre huéspedes, en lo que respecta a la longevidad y fecundidad de las hembras (la fertilidad, por el contrario, no se vio afectada). El huésped también influyó en la duración total del desarrollo de los estados y estadios inmaduros del ácaro y en la supervivencia total acumulada de los mismos. Por último, los valores de los parámetros de la tabla de vida de las poblaciones ensayadas de P. ulmi y, concretamente de la rm, también se vieron afectados, de modo que el mayor valor se obtuvo sobre manzano, mientras que disminuyó de forma muy importante en los casos del rosal, cerezo y chaenomeles (con valores positivos próximos a cero), llegando a ser negativa en el del peral, sobre cuyo huésped, y en las condiciones ensayadas, la población tiende a desaparecer a lo largo del tiempo. De cara a facilitar la disponibilidad de individuos de P. ulmi en laboratorio, a partir de huevos hibernantes en campo, se observó que, cuando la recogida es más tardía, ni el valor de la temperatura ni el tiempo durante el que se sometan a ella los huevos tras su recogida, van a influir en el porcentaje de eclosión, mientras que sí influyen cuando la recogida es más temprana. En este caso, el factor "número de días a los que someten los huevos a bajas temperaturas" es el que afecta de modo más determinante en los porcentajes de eclosión finalmente alcanzados. Cuanto más se prolonga el tiempo en frío, mayor es el porcentaje de eclosión (llegando al 60 % para 100 días, frente al 10 %, para 10). Además, este factor, en el caso de huevos recogidos en fecha temprana, es el único de los ensayados que afecta también al tiempo necesario para la eclosión del 50% de los huevos (T50%), de modo que su valor disminuye a medida que aumenta el número de días en frío. Así, la T50% alcanza un valor de unos 15 días cuando los huevos estaban 100 días en frío y de unos 40-50, cuando estaban 10. Finalmente, para los huevos hibernantes de P. ulmi en campo, se estimó la fecha a la que sucedía el inicio de la postdiapausa (18 y 20 de febrero para los años 2005 y 2007, respectivamente). También se obtuvieron valores para el Umbral mínimo de Desarrollo (UmD) y para el sumatorio teórico de los Grados-Día (DD) en los mismos años (5,47 ºC y 6,13 ºC, respectivamente, para UmD y 55,3 y 276,4, respectivamente, para DD). Estos datos, a falta de ser validados en condiciones de campo, se pueden convertir en una valiosa herramienta para la toma de decisiones en el manejo integrado del ácaro. Tetranychus urticae is a cosmopolitan and polyphagous spider mite pest that causes problems in more than 150 economically important crops. This species is a key pest in many of these hosts. On the other hand, Panonychus ulmi is also a widespread and polyphagous species important as pest of fruit trees and, specially, of the apple tree. The importance of spider mites as pests species have recently increased. The massive use of no selective pesticides has been one of the reasons, because these compounds have dramatically reduced the populations of its natural enemies. This fact, combined with the development of resistances against many acaricides, is the reason why the spider mites are currently one of the most important phytosanitary problems. Taking into account the importance to implement Integrated Pest Management (IPM) programs, developing researches to optimize its implementation in the case of spider mite pest has a special interest. In regard with T. urticae, the effect of two biorational pesticides (the inhibitor of chitin synthesis, flufenoxuron, and the ecdysone antagonist, azadirachtin) has been deeply analysed in this work. On the other hand, the compatibility of both compounds and the entomopathogenic fungus Beauveria bassiana has also been researched. Flufenoxuron showed an important acaricidal effect on eggs, protonymphs, deutonymphs and adults of T. urticae, being especially effective on protonymphs. Meanwhile, azadirachtin also showed an interesting effect on the same spider mite developmental stages (more important on protonymphs and deutonymphs), although lower than in the case of flufenoxuron. When both acaricides were applied on adult females of the pest, the effect was different; flufenoxuron did not affect to the longevity and fecundity, but it has a negative effect on fertility and on the percentage of the progeny survival; on the contrary, azadirachtin only affected the female longevity and fecundity. To know the effect that the pesticides have on the life table parameters of the pest populations, at specific physical conditions, is very interesting in IPM programs. The current work shows that, under the bioassay conditions, flufenoxuron significantly reduced the intrinsic rate of increase (rm) of T. urticae at 2 mg/l. Therefore, at this concentration, mite population increases extremely slowly, with a doubling time (DT) of more than 2,200 days. Similarly, azadirachtin caused a dramatic reduction of the rm when applied at the concentration of 80 mg/l. In fact, the value of the rm was negative, indicating that the treated population tended to disappear (halving every 21 days). Researches about the joint use of pesticides and natural enemies have an obvious relevance in IPM programs. In this study, it was shown that flufenoxuron did not affect the mycelial growth of B. bassiana and, when used with the entomopathogenic fungus on T. urticae larvae, a synergistic effect was observed. Meanwhile, although azadirachtin did reduce the growth of the mycelium of the fungus, when applied together on the mite, a synergistic effect was also observed, although less pronounced than in the case of flufenoxuron. In regard with P. ulmi, the researches were, first, focused on improving their laboratory mass rearing. Secondly, the possibility to obtain individuals from the field was analysed. Finally, the determination of the end of diapause and the modellization of the embryonic development, to predict the hatching date of the P. ulmi eggs in the field, was also researched. The fitness of 12 plant species as P. ulmi hosts was evaluated. The host used to feed the spider mite significantly influenced on biological and life table parameters of the females. So, important differences between hosts were observed with respect to female longevity and fecundity, (fertility, however, was not affected). Hosts also influenced the developmental time and survival of the immature stages of the mite. The higher value of rm was obtained on apple tree, while a dramatically decreasing was observed in rose, cherry and chaenomeles (with positive values close to zero), becoming negative in the case of pear tree. On this host, and under the conditions of the bioassay, the spider mite population tends to disappear over time. Researches to improve the establishment of laboratory colonies of P. ulmi from field overwintering eggs were developed. The factors "temperature" and "period keeping cold" applied in laboratory to collected eggs did not affect the percentage of hatching when the collection was late. On the contrary, when the collection is earlier, both factors had influence on this parameter. The "period keeping cold" is the factor that affects more significantly on the percentage of hatching finally achieved. This percentage is higher as the number of cold days increases (reaching 60% for 100 days, compared to 10% for 10). Moreover, this factor (in the case of eggs collected at early date) is the only one that affects to the required time to get the 50% of egg hatching (T50%). In fact, the T50% value decreases as the number of days in cold increases (T50% reaches a value of about 15 days when the eggs were in cold 100 days and about 40- 50, when they were in cold 10 days). Finally, the date to which the beginning of the postdiapausa of field overwintering P. ulmi eggs happened was estimated (18 and 20 February in 2005 and 2007, respectively). The Lower Developmental Thresholds (LDT) and the Degree Days values (DD) in the same years (5.47 ° C and 6.13 ° C, respectively, for LDT and 55.3 and 276.4, respectively, for DD) were also obtained. These data could become in a valuable tool for decision making in the integrated management of the spider mite. more...

Conservative techniques, such as ground cover management, could help promote viticulture sustainability, which is a goal of conservation biological control, by providing shelter and food sources for predatory insects. A field experiment was conducted in a Mediterranean vineyard to evaluate ground cover management impacts on predatory insect and potential grapevine pest abundance and diversity, both on the ground and in the grapevine canopy. Three different ground cover management techniques (tillage, spontaneous cover and flower-driven cover) were tested for two years (2016 and 2017). Overall, the ground cover management significantly affected the abundance of important epigeal predators, of which carabids, forficulids and staphylinids were the most captured. The carabid abundances under both the cover crop treatments were found to be approximately three times higher compared with that under the tillage treatment. In contrast, the canopy insect abundance in the vineyard was similar among the treatments for both the predators and the potential grapevine pest species. These results indicate that cover crop vegetation can be used in vineyards to enhance predatory insect abundance and may improve agroecosystem resilience, This research was funded by the Ministry of Economy and Competitiveness (AGL2014-53336R). M.G.S.-R. and A.V.-B. were supported by fellowships from the University of La Rioja (Spain) (FPI-UR 2015 and 2018, respectively).
