Conservative biological control promotes the use of native natural enemies to limit the size and growth of pest populations. Although spiders constitute one of the most important groups of native predators in several crops, their trophic ecology remains largely unknown, especially for several generalist taxa. In laboratory, we assessed the predatory behaviour of a wandering spider (the wolf spider Lycosa thorelli (Keyserling, 1877) against several arthropods varying in size and trophic positions, all found in South American soybean and rice crops. As prey we used the bug Piezodorus guildinii (Westwood, 1837) as well as larvae and adults of the moth Spodoptera frugiperda (Smith, 1797), both being considered important pests in Uruguayan crops. We also used several non‐pest arthropods as prey, sarcophagid flies, carabid beetles and wolf spiders. All prey were attacked in more or less high, although not statistically differing, proportions. However, carabids were not consumed, and bugs were consumed in significantly lower proportions than flies. A negative correlation was found between prey size and acceptance rate. Immobilization times were longer against larvae when compared to moths and flies, while predatory sequences were longer for bugs when compared to flies, moths and spiders. In addition, we found a positive effect of prey size on predatory sequence length and complexity. Our results confirm the ability of spiders to attack and feed upon prey with different morphologies, included well‐defended arthropods, and their potential use as natural enemies of several pests in South American crops.

Introducción: Obtener cultivares con alto potencial de rendimiento (RG) y buena estabilidad frente a déficit hídricos es fundamental para sostener e incrementar la producción regional de este cereal. El objetivo de este trabajo fue evaluar el comportamiento de cultivares de trigo caracterizados como diferentes en su tolerancia a déficit hídrico durante la etapa post-floración en un amplio rango de ambientes.
Conclusiones: Estos resultados aportan una nueva caracterización genotípica y destacan a INIA DON ALBERTO como material con muy buen comportamiento, a diferencia de trabajos previos donde se había caracterizado como de comportamiento intermedio. El estudio de la ocurrencia puntual del déficit hídrico en los ambientes evaluados y de otras características ecofisiologicas ayudaría a comprender las bases de la estabilidad de este cultivar a los estreses abióticos. |
