Abstract: This paper studied the development,survival and reproduction of vegetable leafminer (Liriomyza sativae) at eight constant temperatures (12,15,20,25,27.5,30,32.5 and 35℃) with 70%±5% R.H. and 14L◊10Dphotoperiod.The initiative development temperature and the available accumulation temperature were estimated to be 8.77℃ and 295.69 day degrees,respectively.The regression equations of development rate with temperature at various immature stages were given.The survival rates at various immature stages were higher at 20～27.5℃.Most of the death occurred at pupal stage,and no pupae could emerge at 35℃.The longevity of the adult decreased with increasing temperature,and the population growth index reached a peak at 27.5℃.
