High-throughput chemical toxicity testing for beneficial insects: the value of coated vials.

ABSTRACT: Nontarget effects of insecticides used in agriculture can impact the ecosystem services provided by beneficial insects. Understanding the broader effects of chemical usage requires multispecies investigations on the impact of different insecticide active ingredients. In this work, we tested the utility of coated vials as a quick, cheap, and efficient dried residue chemical toxicity assay. This method was compared against dishes sprayed with a Potter tower, which is an industry standard instrument used to apply precise insecticide doses. Our study focused on 2 natural enemies of aphids, larval and adult stages of the Hippodamia variegata (Goeze 1777) ladybird beetle, and the parasitoid wasp, Diaeretiella rapae (McIntosh 1855). These natural enemies were exposed to multiple concentrations of
