| Abstract: | The development of resistance to the insecticide effect of juvenile hormone analogue (AJH-I) in Drosophila was studied. It is found that under the AJH-I treatment metamorphosis in D. virilis was delayed and some insects died. Selection of resistant flies was performed using sublethal dose of AJH-I (viability was 8%). The selection at such dose of AJH-I resulted in an increase in the proportion of resistant flies up to 30% already by the F3, whereafter is fluctuated within the range of 24-46% for further 12 generations. The increase in resistance to the lethal effect of AJH-I was also accompanied by an increase in resistance to its teratogenic effects. An analysis of the kinetics of selection has shown that the AJH-I resistance is controlled by more than one gene. It is established that the increase in resistance is associated with selection of individuals having high activity of juvenile hormone esterase. |
