Laboratory evalution of a translocation double heterozygote for genetic control of Aedes aegypti.

Two pure translocation homozygote stocks, T1/T1 and T3/T3, were used to produce a double translocation heterozygote system designated T1/T3, employing T1/T1 as the male and T3/T3 as the female parent. The double heterozygote showed 73 % sterility when mated to wild females. Tests on mating competitiveness, recombination frequency in the differential segment, insemination rate and inheritance of sterility after release, for four generations in laboratory cages, have been carried out to evaluate the efficiency of this strain as an agent for a population control programme.
