摘　　要：试验结果表明:在17～31℃恒温范围内,稻茎毛眼水蝇的发育速率随温度上升呈逻辑斯蒂曲线趋势。幼虫、蛹存活率、成虫产卵量、种群增长指数随温度的上升呈抛物线趋势。卵孵化率在20～31℃范围内无显著差异,均在92％以上。在17℃和35℃时,孵化率下降至86.67％和76.36％。在35℃时,幼虫不能存活,成虫不产卵。Under constant temperature conditions in the range of 17 -31℃ ,the development rate of black rice stem fly Hydrellia sasakii increased with the temperature as logistic curve,while the survivals of larvae and pupae,fecundity of adults and population trend index increased with temperature as parabola. There were no significant differences among the hatching rates of eggs in the range of 20-31℃ ;under 17 and 35℃ ,the hatching rates reduced to 86. 67% and 76. 36% .respectively. Under 35℃,the larvae cannot survive and the adult cannot oviposit.
