Dieldrin Susceptibility: Partial Restoration in Anopheles Selected with a Carbamate

G. P. Georghiou 1 and R. L. Metcalf 1

1 Department of Entomology, University of California, Riverside

Selection of dieldrin-resistant Anopheles albimanus Wied. and normal Culex pipiens quinquefasciatus Say with m-isopropylphenyl methylcarbamate for 21 and 30 generations, respectively, resulted only in vigor tolerance to this and other aryl methylcarbamates. However, it caused substantial restoration of dieldrin- and DDT-susceptibility in Anopheles by increasing the frequency of homozygous susceptible phenotypes from 10 to 83 percent.
