Amplified esterase genes and their relationship with other insecticide resistance mechanisms in English field populations of the aphid, <i>Myzus persicae</i> (Sulzer)
12 Aug 2002
Abstract excerpt
Myzus persicae samples were collected from populations present on a range of field crops between 1997 and 2000. A combination of biochemical, DNA-based diagnostics and bioassays was used to assess the presence of three insecticide resistance mechanisms: elevated carboxylesterase (E4 or FE4), insensitive acetylcholinesterase and insensitive sodium channels (knockdown resistance, kdr). For the carboxylesterases,...
