At 10 ℃, 15 ℃, 20 ℃, 25 ℃, 30 ℃, the developmental stages were 71 8d, 47 5d, 33 7d, 16 3d and 14 1d respectively. The developmental threshold temperatures of eggs and 1st to 3rd instar larvae and pupae were (11 5 ± 2 8) ℃, (7 6 ± 3 2) ℃, (8 8 ± 4 3) ℃ and (10 3 ± 2 9) ℃ , (53 ± 2 1) ℃, respectively. The daily effective accumulated temperatures were (39 98 ± 10 6) ℃, (45 5 ± 10 4) ℃, (2944 ± 39) ℃, (2157 ± 5 5 ° C, (16 9 9 ± 2 2 4) ° C. Six regression equations between the developmental stages and temperature of each insect state were obtained, which could be used to predict the age-dependent larvae, the prediction of period and the prediction of effective accumulated temperature
