Mode of Action

Dinotefuran acts through contact and ingestion and results in the cessation of feeding within several hours of contact and death shortly after. Dinotefuran does not inhibit cholinesterase or interfere with sodium channels. Therefore, its mode of action is different from those of organophosphate, carbamate, and pyrethroid compounds. It appears that Dinotefuran acts as an agonist of insect nicotinic acetylcholine receptors, but it is postulated that Dinotefuran affects the nicotinic acetylcholine binding in a mode that differs from other neonicotinoid insecticides. It is reported that Dinotefuran was highly active on a certain silverleaf whitefly strain which developed resistance against imidacloprid.
