Inheritance of resistance to fenthion in Culex pipiens fatigans Wied. 1970

C Dorval, and A W Brown

The insecticide fenthion, which shows great promise for controlling the filariasis vector Culex pipiens fatigans, has been found in the laboratory to induce a certain amount of resistance. As the biochemical nature of fenthion resistance was known to be due to an increase in a particular esterase activity, the inheritance of the character was investigated in the present study. It was found to be mainly due to a single slightly recessive gene associated with linkage-group 2, and the increase in detoxifying esterase activity showed a similar inheritance.
