Mutations of acetylcholinesterase which confer insecticide resistance in insect populations.

Abstract excerpt

Resistance-modified acetylcholinesterases have been described in many insect species and sequencing of their genes has allowed several point mutations to be described. Most mutations line the active site gorge. Each mutation provides a specific resistance pattern: it confers resistance to one insecticide but may increase sensitivity to another. Most mutations alter hydrolysis of the substrate by decreasing the...
