Abstract excerpt
Insecticide resistance poses a major challenge to global pest management, yet its cascading effects on ecological networks remain poorly understood. Here, we show that target-site-resistant herbivorous insects can accumulate unmetabolized insecticides and inadvertently function as "toxic prey," impairing the fitness of their natural enemies. Using neonicotinoid- and spinosyn-resistant Myzus persicae and...
