【Abstract】 The banana moth Opogona sacchari(Bojer) is destructive insect pest.This paper dealed with its biology and the influence of temperature on its development, survival, fecundity and longevity in condition of laboratory. The results showed that the temperature had a significant effect on its development duration.The development temperature thresholds for egg, larvae ,pupae and generation were (11.2±3.5), (8.8±1.4), (10.97±1.4) and (11±1.8) ℃,respectively. The effective accumulated temperature of 75.4,729.0,206.8 and 876.5 day degree for egg, larvae, pupae and generation respectively. The durations of egg were 13, 7, 4.3, 4, 5 and 5 days under the condition of 15, 20, 24, 28, 30 and 33 ℃ with RH 75%. The survival rates of larvae were from 37% to 46% at above temperature. However, the larvae did not complete their development at 33 ℃. The development duration of larvae were (141.4±10.2), (63.4±2.4), (47.6±2.5), (32.9±1.9), (35.5±1.6) days.While they were (44±3.7), (21.7±3.1), (15.1±2.1), (10.9±1.4) and (12.8±5.2) days respectively at above temperature of pupae. The average longevity of adults decresed with increasing temperature, 2.7～15.7 days for female and 1.5～12.6 days for male at 15～33 ℃.更多还原
