Abstract：In order to study the biological characteristics of Trichopria drosophilae at different ages after parasitizing Drosophila melanogaster,this experiment was conducted to investigate the parasitic rate of 1～10-day-old T.drosophilae adults on D.melanogaster pupae,the development duration and female proportion of T.drosophilae offspring,and the dynamic change of pupae weight of D.melanogaster after parasitized by T.dros-ophilae.The results showed that there was significant difference in parasitic rate between different ages of T.drosophilae on D.melanogaster pupae.The parasitic rate of 7-day-old T.drosophilae was the highest(58.89±2.94)% ,and that of 1-day-old T.drosophilae was the lowest(30.00±1.94)% .However,ages of T.dros-ophilae had no significant effect on developmental duration and female proportion of its offspring after parasiti-zing D.melanogaster pupae.In addition,the weight of D.melanogaster pupae was significantly reduced after parasitized by T.drosophilae.It was concluded that D.melanogaster pupae could be parasitized by 1～10-day-old T.drosophilae adults,of which,the age in 7 days was optimum.These results could provide theoretical ba-ses for breeding in quantity and application of T.drosophilae.
