Abstract:This paper dealt with the effects of the temperatures on the development,survival and fecundity of the banana moth,Opogona sacchari (Bojer),and its the life tables at 19 ℃, 22 ℃, 25 ℃, 28 ℃, 31 ℃, 34 ℃ were also established.The results showed that the suitable range of the temperature for the development, survival and the reproduction of this insect ranged from 19 ℃ to 31 ℃.The average fecundity was maximal as the 290.9 eggs laid per female at 22 ℃.The shortest duration of the generation was recorded as 46.1 days and the highest generation survival rate was 0.37 at 31 ℃.The development threshold and the total effective temperature of eggs, larvae, pupae and eggs to adults calculated by using linear regress method were 11.15 ℃, 7.80 ℃, 12.51 ℃, 9.27 ℃ and 95.66, 613.88, 173.11, 758.80 day-degrees, respectively. The population trend index (I) of the banana moth were 32.10, 33.30, 38.58, 40.54, 45.12 and 0.77, respectively at 19 ℃, 22 ℃, 25 ℃, 28 ℃, 31 ℃, 34 ℃. The data at different temperature showed that the index I increased with the temperature increasing in 19 ℃ to 31 ℃, and the population would be negative increase at 34 ℃.The experimental results showed that the eggs of the banana moth could bear higher temperature, but 38 ℃ was ultimate temperature of the hatching for the eggs. 90%RH was the optimal surrounding humidity of the hatching for the eggs, and 45%RH was the lowest humid condition. The hatching rate of the eggs was influenced hardly in 20 min for the eggs immersed in water, but the hatching rate would decrease evidently more than an hour. The survival rate of the larvae was still 93.33% at 0 ℃ for 72 h, but most of the larvae died at -2 ℃ for 72 h, and all died at -5 ℃ for 48 h.
