摘要/Abstract

摘要： 用添加不同叶粉成分的人工饲料连续饲养5代斜纹夜蛾（Spodoptera litura）,筛选有利于斜纹夜蛾生长发育的“叶粉因子”人工饲料。结果表明,取食添加白菜（Brassica pekinensis）叶粉的人工饲料2~5代斜纹夜蛾幼虫存活率、化蛹率和羽化率最高,幼虫存活率、化蛹率、蛹重和羽化率5代均值均显著高于取食未添加叶粉的人工饲料和天然饲料,且随着饲养代数的增加幼虫存活率和化蛹率下降幅度最小,各世代间羽化率无显著差异,适合在实验室连续多代饲养。添加藜（灰菜）（Chenopodium album）叶粉的人工饲料幼虫存活率、蛹重和羽化率5代均值均显著高于取食未添加叶粉的人工饲料和天然饲料,化蛹率和蛹重均值与添加白菜叶粉的人工饲料呈显著差异。

Abstract: The artificial feed with different leaf powder ingredients was used to feed 5 generations of Spodoptera litura continuously. The “leaf powder factor” ingredient feed which was beneficial to the growth and development of Spodoptera litura was screened. The results showed that the survival rate, pupation rate and emergence rate of 2~5 generations of Spodoptera litura larvae fed the artificial diet supplemented with cabbage （Brassica pekinensis） leaf powder were the highest; the survival rate, pupation rate, pupal weight and eclosion rate of the five generations were significantly higher than those of larvae fed the artificial diet without leaf powder and the natural diet. With the increase of rearing generations, the survival rate and pupation rate of larvae decreased the least, and there was no significant difference in emergence rate among generations, which was suitable for continuous feeding in the laboratory. The survival rate, pupal weight and eclosion rate of larvae fed the artificial diet supplemented with Chenopodium album leaf powder were significantly higher than those of larvae fed the artificial diet without leaf powder and the natural diet. However, the average pupation rate and pupal weight of larvae fed the artificial diet supplemented with Chenopodium album leaf powder were significantly different from those of larvae fed the artificial diet supplemented with cabbage leaf powder.
