The use of pesticides contributes to the productivity and the quality of the cultivated crop. A large portion of the agricultural produce is not consumed as it is not an edible part or the quality of the product is too low. This waste of agricultural produce can be valorised as a substrate for the production of certain insects for human consumption. However, pesticides applied on the plants might accumulate during the life cycle of the insects fed on the waste materials and may cause a health risk to humans consuming the insects. Pesticide residues in larvae of the yellow mealworm, Tenebrio molitor, were investigated. We monitored the accumulation of pesticides in the larvae upon consumption of contaminated fresh produce. An increased uptake rate by the insects was found for pesticides with higher Kow-values. Excretion of pesticides by the insect was inversely related to the log(Kow) values of the pesticides.
农药的使用有助于提高农作物的产量和质量。很大一部分农产品未被消费，因为它不是可食用部分，或者产品质量过低。这种农产品的浪费可以作为生产某些供人类食用昆虫的底物加以利用。然而，施用于植物上的农药可能会在以废料为食的昆虫生命周期中积累，并可能对食用这些昆虫的人类造成健康风险。我们对黄粉虫（Tenebrio molitor）幼虫中的农药残留进行了调查。我们监测了幼虫在食用受污染新鲜农产品后农药的积累情况。发现昆虫对具有较高辛醇-水分配系数（Kow）值的农药的吸收速率增加。昆虫对农药的排泄与农药的log（Kow）值呈负相关。
