The fruit fly Drosophila melanogaster,is one of the most important pests for blueberry.The adults lay their eggs under the peel of blueberry,while the larvae eat the pulp,which has strong impact on sales,storage and processing for blueberry.In order to find out the effect of antibiotic rifampicin on population of Drosophila melanogaster,and provide a reference basis for the population reproduction of Drosophila melanogaster,by means of feeding different concentration of rifampicin at 0.04,0.08,0.16,0.32,0.64,1.28,2.56 mg·mL~(-1),the suitable concentration(0.64 mg·mL~(-1))to F0 and F1 generation of Drosophila melanogaster were screened to further study.The results showed that there was a significant reduction in the amount of spawning when feeding rifampicin above 0.64 mg·mL~(-1)(P0.05),but no impact below 0.64 mg·mL~(-1).After feeding rifampicin to female fruit fly(C0)in F0 generation,the developmental duration of offspring female worm were significantly higher than control whiteflies(P0.05),and the amount of pupation of treatment B0(feeding rifampicin to male fruit fly)were significantly higher than treatment C0 and D0(feeding rifampicin to male and female fruit fly)(P0.05).In F1 generation,there was significant changes in the amount of pupation and feather,the developmental duration and the sex ratio in treatment b1 and C1(P0.01),and treatment D1 led to significant reduction in the amount of spawning(P0.01),which from 14.47 down to1.93.They could not grow up to adult because of the dramatic decrease of the amount of pupation and feather.The results showed that the amount of spawning of offspring fruit fly were reduced by the antibiotic rifampicin.
