Sensitivity of spiders from different ecosystems to lambda-cyhalothrin: effects of phylogeny and climate.

Our study underlines the high sensitivity of spiders to lambda-cyhalothrin, which can lead to unintended negative effects on pest suppression in areas treated with this insecticide. The strong differences observed between families and genera indicate that the functional composition of spider communities would change in affected areas. Overall, the variation in spider sensitivity suggests that multi-species investigations should be more widely considered in pesticide risk assessment. This article is protected by copyright.
