Mechanisms of monocrotophos resistance in cotton bollworm, Helicoverpa armigera (Hübner)
17 Oct 2002
Abstract excerpt
Insensitive acetylcholinesterase was identified as a resistance mechanism by comparing biochemical analysis with a laboratory selected monocrotophos resistant cotton bollworm (RR: 200) and the susceptible strain. The cDNA encoding AChE was cloned by the method of RACE (rapid amplification of cDNA ends). The complete AChE gene deduced from the cDNA consisted of a putative signal peptide of 32 amino acid residues,...
