Carbofuran resistance of Leptinotarsa decemlineata
Assessment of the progression of carbofuran resistance in Leptinotarsa decemlineata (EPPO A2 pest) as well as its characterization and mechanisms were the objects of investigations carried out in Michigan, US.
Colorado beetles were subjected to a sublethal dosage (80% mortality rate) of carbofuran and subsequently selected. Already after the fourth generation the resistance to carbofuran was >100 fold.
The authors estimated that the resistance is inherited via a single, autosomal, incompletely dominant gene, resulting in a decreased acetylcholinesterase sensitivity.
