The life-cycle stages and developmental durations of each stage of D.genutia were observed by individually rearing eggs, larvae and pupae under different temperatures and photoperiods in climatic chambers. Developmental threshold temperatures ( C) and effective accumulated temperatures (K) of eggs, larvae and pupae were measured. In long-day treatment (LD=15:9) and at different temperatures (17.5℃, 20.0℃, 22.5℃, 25.0℃, 27.5℃, 30.0℃), the durations of egg stage were 9.29 days, 4.90 days, 4.91 days, 3.97 days, 3.54 days, and 3.20 days, respectively; The durations of larva stage were 38.04 days, 17.89 days, 17.13 days, 10.82 days, 9.92 days, and 10.20 days, respectively; The durations of pupa stage were 22.71 days, 13.72 days, 12.00 days, 7.73 days, 7.46 days, and 6.80 days, respectively. In short-day treatment (LD=9:15) and at different temperatures (17.5℃, 20.0℃, 25.0℃, 30.0℃), the durations of egg stage were 9.04 days, 8.20 days, 4.11 days, and 3.04 days, respectively; The durations of larva stage were 30.08 days, 18.54 days, 13.29 days, and 9.54 days, respectively; The durations of pupa stage were 21.19 days, 13.40 days, 9.64 days, and 6.38 days, respectively. The results showed that in terms of T= C+ KV, C and K of eggs, larvae and pupae were determined as follows: T egg=11.10+55.15 V, T larva=14.06+131.62 V, and T pupa=13.46+98.95 V. These results suggested that temperature has more significant influence on the growth and development of immature stages of D. genutia compared with photoperiods, and thus temperature is a key factor in determining the developmental velocity of immature stages of D. genutia.
