摘　　要：本文研究了补充不同营养对草地贪夜蛾成虫寿命及生殖力的影响,为草地贪夜蛾的人工饲养及种群动态的预测预报提供理论依据。在温度(25±1)℃,湿度70%±5%,光照L∥D=16 h∥8 h的养虫室,分别以6种不同营养物和蒸馏水对成虫补充营养,观察记录成虫产卵期、成虫寿命、产卵量及卵孵化率。结果表明:补充蒸馏水的处理组产卵前期显著短于其他处理组;10%蜂蜜水及10%蔗糖水处理组的产卵期及雌成虫寿命均显著长于其他处理组;且10%蜂蜜水处理组的产卵量及卵孵化率最高,分别为983.20粒和98.07%。综合以上结果:室内饲养草地贪夜蛾时,成虫期营养补充以10%蜂蜜水为最佳。In order to provide theoretical basis for artificial rearing and prediction of population dynamics of Spodoptera frugiperda,the effects of different nutrition supplementation on adult longevity and fecundity were studied.In a rearing room with a temperature of(25±1)℃,humidity 70%±5%,L∥D=16 h∥8 h,the adult longevity,fecundity and egg hatching rates of S.frugiperda were recorded using six different nutrients and distilled water as a nutritional supplement.The results showed that the pre-oviposition period of the adults supplied with distilled water was significantly shorter than that of other treatments,and the oviposition period and the female adult longevity the adults treated with 10%honey water and 10%sucrose water were significantly longer than other groups.And the adults supplied with 10%honey water possessed the highest fecundity and hatchability,which were 983.20 eggs per female and 98.07%,respectively.In conclusion,10%honey water was the best choice for indoor breeding of S.frugiperda.
