Toxicity of four systemic neonicotinoids to adults of Anoplophora glabripennis (Coleoptera: Cerambycidae).

As part of the ongoing evaluation of different systemic insecticides for prophylactic treatment of trees, responses of the beetle Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae) to different doses of four systemic neonicotinyl insecticides were studied. Adult beetles were provided with twigs or leaves of trees treated with different concentrations of imidacloprid to evaluate the toxicity of the insecticide through ingestion or contact or through both. Adult beetles also were provided with twigs of host plant treated with clothianidin, dinotefuran, and thiamethoxam to establish dose response of the beetle to these insecticides.
