Abstract
Cyclodiene insecticide resistance has accounted for over 60% of reported cases of insecticide resistance. In Drosophila melanogaster resistance is associated with a single base pair substitution in the GABA receptor/chloride ion channel gene Rdl. This substitution predicts the replacement of an alanine with a serine in the second membrane spanning domain, the region thought to line the chloride ion channel pore. Here we report, via the use of degenerate primers in the polymerase chain reaction, that precisely the same substitution is present in three pests from three different insect orders: the house fly (Diptera), red flour beetle (Coleoptera) and American cockroach (Dictyoptera). This finding suggests that there are a limited number of mutations that can confer resistance to cyclodienes, putative channel blockers, while still maintaining adequate chloride ion channel function. The conservation of the resistance-associated mutation between Drosophila and pest insects directly validates the approach of using this insect as a model system for isolating and studying resistance genes. The importance of single base pair substitutions in the evolution of pesticide resistance and in the design of molecular monitoring techniques is discussed.
