The codling moth, Cydia pomonella (Lepidoptera; Tortricoidea) is a major pest of pome fruitand walnut orchards in the world. Due to the intensive chemical control C. pomonella has developed a high resistance to various insecticides. One of the mechanisms of the resistance is acetylcholinesterase insensitivity to carbamates and organophosphates. The insensitivity is based on mutations in one of two genes for acetylcholinesterase. This study deals with testing a hypothesis suggesting that one gene coding for acetylcholinesterase in the codling moth was translocated to the Z sex chromosome. The hypothesis has been latersupported by sex-linked inheritance of insecticide resistance in a related species, Grapholita molesta, and also by a large size of sex hromosomes in the codling moth.
