The present paper deals with the effects cf ambient temperature on the development and the population growth of pink rice borer.The result showes that the correlation between the developmental rate of this species at the immature stage and the environmental temperature fits in the logistic curve,The threshold of development and the effective thermal constant for a generation are 10.55℃ and 649.21 day-degree respectively.The lowest generation mcrtality cf borers is in the immature stage at 29℃, while the hig...
