Distribution of pesticides in agroecosystem food webs differ among trophic groups and between annual and perennial crops

Pesticides threaten biodiversity, but their impact on agroecosystem food webs remains unclear. Our study reveals pesticides, including banned ones, enter local food webs from surrounding landscapes through diverse routes. Trophic groups and agroecosystem type influence the number of detected pesticides. We found that insecticides and fungicides bioaccumulate, while herbicides (bio)degrade. Our findings emphasize how species traits and agroecosystem characteristics collectively impact pesticide distribution in food webs. This study provides crucial insights into the ecological consequences of pesticide use, informing sustainable pest management and biodiversity conservation.
