Aphicidal activity of imidacloprid against a tobacco feeding strain of Myzus persicae (Homoptera: Aphididae) from Japan closely related to Myzus nicotianae and highly resistant to carbamates and organophosphates
Bulletin of Entomological Research 86 (2), 165-171
Abstract: We investigated the resistance potential of a red-coloured Japanese strain (JR) of a tobacco feeding form of Myzus persicae (Sulzer) of the M. persicae species complex closely related to the tobacco aphid Myzus nicotianae Blackman. Bioassays were performed with a range of insecticides, imidacloprid, nicotine and cartap, thought to act on nicotinic acetylcholine receptors in vivo, as well as with two conventional insecticides, pirimicarb and oxydemeton-methyl, acting on acetylcholinesterase (AChE). Compared to a susceptible strain, JR showed high resistance to pirimicarb and oxydemeton-methyl, but was far less resistant to nicotine, cartap and imidacloprid. Imidacloprid was, among the insecticides tested, the most active compound in contact and ingestion bioassays. Compared to the susceptible strain, JR showed four- to seven-fold resistance to imidacloprid.
