Host-mediated insecticide sequestration in target-site-resistant pests impacts parasitoid fitness and evolution.

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...
