Bases de la resistencia a preparados bioinsecticidas basados en "Bacillus thuringiensis" en diferentes especies de insectos
2015
El empleo de insecticidas en la agricultura moderna resulta fundamental para obtener unos niveles óptimos de productividad. Actualmente se tiende al empleo de bioinsecticidas dados los efectos perniciosos de la mayor parte de los insecticidas convencionales. Los preparados bioinsecticidas basados en las proteínas cristalinas insecticidas (toxinas Cry) de “Bacillus thuringiensis” (Bt) son los de mayor venta del mercado y las plantas transgénicas protegidas por estas proteínas, están siendo cultivadas a escala mundial. La vida útil de este bioinsecticida podría verse limitada por la aparición de poblaciones de insectos resistentes si no se adoptan las medidas oportunas de manejo de resistenci…
Data from: Parasitic wasp-associated symbiont affects plant-mediated species interactions between herbivores
2018
Microbial mutualistic symbiosis is increasingly recognised as a hidden driving force in the ecology of plant–insect interactions. Although plant‐associated and herbivore‐associated symbionts clearly affect interactions between plants and herbivores, the effects of symbionts associated with higher trophic levels has been largely overlooked. At the third‐trophic level, parasitic wasps are a common group of insects that can inject symbiotic viruses (polydnaviruses) and venom into their herbivorous hosts to support parasitoid offspring development. Here, we show that such third‐trophic level symbionts act in combination with venom to affect plant‐mediated interactions by reducing colonisation o…
