τ-Fluvalinate residues in bees, honey and wax were measured in two experimental hives treated with Apistan to test a multi-compartmental predictive model. Pesticide residues were monitored for 30 days after treatment in bees and for up to 180 days in honey and wax. Concentrations ranged between 14 and 160 ng g−1 f.w. in bees and between 98 and 1630 ng g−1 in wax, while no residues were detected above...
A new hive model is proposed for the assessment of the distribution and fate of pesticides in the hive ecosystem. Based on the chemical used, the model draws a dynamic picture of pesticide contamination in the hive, calculating contamination trends and concentration levels in the various hive components (e.g. bees, wax and honey). The proposed model is validated using empirical data on τ-fluvalinate...
