摘 要 ：在恒温 1 5,2 0 ,2 5,3 0和 3 5℃下 ,对美洲斑潜蝇在菜豆上的发育和繁殖做了研究。结果表明 ,在 1 5～ 3 5℃范围内 ,未成熟期各虫态 (卵、幼虫和蛹 )的发育历期随温度的升高而缩短 ,发育速率呈逻辑斯蒂曲线变化 ;卵期孵化率在 2 5℃中最高 ;各温度下幼虫期存活率最高 ,低温 1 5℃和高温 3 5℃对蛹的存活有明显抑制作用 ,1 5℃时蛹的死亡率达 3 9.6%。成虫寿命一般在 2 0 d以内 ,与温度呈直线负相关 ;繁殖力最高可达 2 81 .91粒卵 /雌 ,平均产卵量与温度关系呈抛物线趋势。

Abstract:The development times,survival and fecundity were determined for Liriomyza sativae on bean at conditions of 15,20,25,30 and 35℃,80% RH and 12∶12 L ∶ D .The results showed that the developmental rate of immature stages of L.sativae increased with increasing temperature.A logistic curve model was used to simulate the trends in temperature range from 15℃ to 35 ℃.the higher percentage of hatch rate occurred at 25℃.The survival rates of larvae were highest among all developmental stages at five...
