Workshop; 8th Latin American Pesticide Residue Workshop; 2021

During foraging flights, honey bees settled in agricultural ecosystems may encounter glyphosate residues on flowers of both cultivated and native plants growing in semi-natural habitats within the landscape. The configuration and heterogeneity of the landscape and the agricultural management in which the bee colonies are located, have direct and indirect implications on the presence and survival of bees. In this work, we were interested to analyze the relationship between landscape configuration and the presence of pesticides in honey. In particular, we tested the relationship between the presence of glyphosate and AMPA residues in honey and some metrics of habitat configuration. We expect a higher presence of glyphosate and AMPA as the proportion of crop lands in the landscape is increased and the connectivity of semi-natural habitats is decreased
