测定了在 2 5℃ ,相对湿度 70 %～ 80 %条件下 ,补充不同营养对小菜蛾成虫寿命及繁殖力的影响 ,分别喂饲 10 %的蔗糖、葡萄糖、蜂蜜水 ,以清水为对照 ,结果表明 :补充不同的营养对小菜蛾成虫寿命及繁殖力之间存在明显差异。以喂饲蔗糖的成虫平均寿命历期最长 ,为 17 1天 ;喂饲葡萄糖的产卵量最多 ,平均每头产卵 16 6 3粒。并测定了小菜蛾的产卵期及孵化率
The effects of supplementation with different nutrients on the lifespan and fecundity of the diamondback moth, Plutella xylostella were determined under the conditions of 25 ℃ and 70% ~ 80% relative humidity. 10% sucrose, glucose and honey water were fed respectively, and the results were as follows The results showed that there were significant differences in the lifespan and fecundity of adult Plutella xylostella when supplemented with different nutrients. The average lifespan of adults feeding on sucrose was the longest, which was 17 1 days. The fecundity of feeding glucose was the highest, with an average of 16 6 eggs per head. The oviposition period and hatching rate of Plutella xylostella were determined
