Neonicotinoids and pyrethroids are some of the most commonly applied and detected insecticides used in agriculture. Residues of these insecticides accumulate in soil and can affect non-target soil-dwelling insects. We determined the comparative toxicity of two neonicotinoids (imidacloprid and thiamethoxam) and two pyrethroids (bifenthrin and tefluthrin) under direct topical application on two Nicrophorus spp based on exposure thresholds for honey bees, Apis mellifera. We tested the effects of soil residues on breeding by Nicrophorus orbicollis. Burying beetles are sensitive to some compounds and methods to reduce run-off and pesticide drift should be undertaken to protect natural areas that support burying beetles.
