Pervasive sublethal effects of agrochemicals on insects at environmentally relevant concentrations.

Insect biomass is declining globally, likely driven by climate change and pesticide use, yet systematic studies on the effects of various chemicals remain limited. In this work, we used a chemical library of 1024 molecules-covering insecticides, herbicides, fungicides, and plant growth inhibitors-to assess the impact of sublethal pesticide doses on insects. In , 57% of chemicals affected larval behavior, and a higher proportion compromised long-term survivability.
