[Organophosphate and carbamate resistance in Myzus persicae Sulzer and Phorodon humuli Schrank (Homoptera: Aphididae): Biological and biochemical considerations]
Mitteilungen der deutschen Gesellschaft für allgemeine und angewandte Entomologie 13, 227-232
Abstract: Acetylcholinesterase (AChE) inhibitors such as organophosphates and carbamates still represent a major class of insecticides. The green peach aphid, Myzus persicae (Sulzer), and the damson hop aphid, Phorodon humuli (Schrank) (Hemiptera: Aphididae), are two agriculturally important aphid pest species and resistance to organophosphates and carbamate insecticides in those species is quite common. Biological and biochemical studies with several compounds such as triazamate (ester and acid), pirimicarb, oxydemeton-methyl, paraoxon, methamidophos and demeton-S-methyl were undertaken in laboratory and field strains. AChE of some field strains of P. humuli was up to 100-times less sensitive towards triazamate than AChE from M. persicae already described as insensitive earlier. Furthermore, we also describe the adaption of a new sensitive microfluorimetric enzyme assay useful to classify acetylcholinesterase genotypes in equivalents of single aphids.
