New evidence points to substantial impacts of exposure pesticide residues in soil for a range bee taxa that have close regular contact with this substrate. Among others, the risk is high bumblebee (Bombus spp.) queens hibernating agricultural soils. An important question whether can detect and avoid pesticide-contaminated soils, or they might be attracted such agrochemical residues. To address question, we performed multiple-choice preference experiment which newly emerged impatiens) were given access arrays 36 crates treated different pesticides large mesh-covered enclosures. Five most commonly encountered soils (boscalid, chlorantraniliprole, clothianidin, cyantraniliprole, difenoconazole) selected testing at two contamination levels (lower higher), based on field-realistic estimates. Bumblebee consistently avoided pesticide-free both levels, while showing no avoidance any pesticide-treated types. At lower level, 1.3 2.4-fold less frequently average than spiked none from higher group soil. This apparent increases likelihood potential hazard during hibernation, critical highly vulnerable period their annual life cycle.
