Abstract: The pupae of Drosophila melanogaster were irradiated by three kinds of ultraviolet lamps (UVA, UVB and UVC), and the effects of irradiation on the eclosion rate, sex ratio, flight rate, dead pupa rate, adult dry weight, pupa weight, F1 eclosion rate, F1 sex ratio, F1 dead pupa rate and F1 adult dry weight were studied. The results showed that the pupa emergence rate of D. melanogaster was significantly reduced after irradiation, among which the pupa emergence rate of D. melanogaster exposed to UVB for 6 h was the lowest (10.00%). The average sex ratio of 9 h group after UVA irradiation was 2.32, which was significantly higher than that of other treatment groups. After UVB irradiation, the pupa emergence rate of D. melanogaster decreased significantly, among which the pupa emergence rate of D. melanogaster was as low as 4.00% after 6 h of UVB treatment. The death rate of pupae in the group exposed to UVB was significantly higher than that in the control group and other groups, and the average death rate of pupae in the group exposed to UVB for 6 h reached 89.33% and the highest was 94.00%. After UV irradiation, pupa weight of each group increased significantly compared with that of the control group. After UVB and UVC irradiation, the dry weight of adult D. melanogaster was significantly lower than that of the control group. After UV irradiation, the dry weight of D. melanogaster F1 adult decreased compared with the control group, and the difference was significant. This study can provide reference for UV mutagenesis and biological control of insect pests.
