摘　　要：１９９４－１９９５年对稻茎毛眼水蝇在水稻四个生育期（苗期、分蘖期、孕穗期、齐穗期）上的生命参数进行了研究。结果表明：水稻生育期对卵和蛹历期、存活率以及成虫寿命无明显影响，但幼虫取食不同生育期水稻后，其存活率和成虫繁殖力有显著的差异。幼虫存活率和成虫繁殖力大小依次为取食孕穗期幼穗＞分蘖期叶片＞苗期叶片＞齐穗期叶片。The life parameters of Hydrellia sasakii on rice at 4 growth stage (seedling, tillering, booting, heading) were studied in 1994-1995. The results showed that, growth stage of rice exerts no significant influence on the duration and the survival rate of egg and pupa, the lifespan of adults. But there were significant differences among the survival rate of larvae and fecundity of adults when the larvae fed on various diets. The difference of the survival rate of larva and the fecundity of adults were: larvae fed on young panicles of booting stage>blade of tillering stage>blade of seedling stage>blade of late earing stage.
