Abstract

Resistance to the synthetic pyrethroid cypermethrin in Aedes aegypti was induced in the laboratory and the genetics of its inheritance is studied and described in this paper. To synthesise a Homozygous Resistant (R) and Susceptible (S) strains, late third instar larvae were exposed to a diagnostic dose of 0.004 mg/L for 33 and 13 generations respectively. The two contrasting strains were crossed for genetic analysis aimed at determining inheritance pattern of cypermethrin resistance (cyp). The logdosage probit mortality relationships and degree of dominance (D) was calculated. The gene cyp in Ae. aegypti is found to be autosomal, monofactorial with incomplete dominance.
