Soil-applied imidacloprid was translocated to nectar (verified residue analysis) and reduced survival of nectar-feeding Harmonia axyridis, Hippodamia convergens, Coleomegilla maculata, Chrysoperla carnea, and Anagyrus pseudococci

Species 1: Hymenoptera Encrytidae Anagyrus pseudococci
Species 2: Neuroptera Chrysopidae Chrysoperla carnea (green lacewing)
Species 3: Coleoptera Coccinellidae Hippodamia convergens (convergent lady beetle)
