| 摘 要： | 在63%～100%相对湿度范围内，稻茎毛眼水蝇卵、幼虫和蛹历期差异不显著。幼虫、蛹存活率和世代存活率、成虫产卵量、寿命和种群增长指数随湿度增加呈抛物线变化趋势。当相对湿度分别为80.87%、77.76%、81.26%、78.61%、78.80%、80.70%时，其幼虫、蛹和世代存活率最高，产卵量最多，寿命最长，种群增长指数最大。

| Abstract: | Under the relative humidity ranged from 63 % to 100%, there were no significant difference among the durations of egg, larva or pupa stage of Hydrellia sasakii. The survival rate of larva or pupa and whole genera tion, the number of egg oviposition and the lifespan of adult, population trend index exhibited parabolically trend in crease with the humidity. When the relative humidity is 80. 87%, 77. 76%, 82. 26%, 78. 61%, 78. 80%,80. 70%, respectively, the survival rate of larva or pupa and whole generation was the highest, the number of egg oviposition was the most, the lifespan of adult was the longest, the population trend index was the largest. |
