摘要：

本研究旨在探讨蠋蝽对银纹夜蛾幼虫的生物防治潜能。在室内控制光、温、湿条件下，用新鲜萝卜叶人工饲养的银纹夜蛾2~5龄幼虫分别对蠋蝽2~5龄若虫及成虫在不同密度下进行饲喂试验，过程中观察记录蠋蝽的捕食特性及各处理银纹夜蛾幼虫的存活数量。结果表明，蠋蝽2~5龄若虫及成虫在不同密度下对银纹夜蛾2~5龄幼虫的总捕食量均存在显著性差异(P=0.000)。蠋蝽自身密度显著影响其捕食行为及能力，其捕食总量均随蠋蝽自身密度的增加呈显著上升趋势，而其平均单头捕食量均随自身密度的增加呈降低趋势。此外，蠋蝽的捕食量与龄期大小存在显著正相关性，即龄期越大，捕食量亦越大，无论是总捕食量还是平均单头捕食量，蠋蝽成虫均高于2~5龄若虫。蠋蝽对银纹夜蛾2~5龄幼虫有不同程度的捕食作用，是一种有应用潜力的捕食性天敌，其成虫及4~5龄期若虫具有较强捕食能力，建议生产上使用成虫及4~5龄期若虫防治银纹夜蛾幼虫，可达到较好的防治效果。

Abstract:

The aim is to clarify the biological control potential of Arma chinensis to larvae of Argyrogramma agnata. Under indoor controlled light, temperature and humidity conditions, the nymphs and adults of A. chinensis were fed with the 2nd to 5th stage larvae of A. agnata in different densities, the predation characteristics of A. chinensis and the survival number of larvae of A. agnata in each treatment were observed and recorded. The results showed that there were significant differences in the total predation amount of 2-5 instar nymphs and adults of A. chinensis against the larvae of A. agnata at different densities (P=0.000). The density of A. chinensis significantly affected its predatory behavior and ability. The total predation increased with the increase of the density of A. chinensis, while the average predation per head decreased with the increase of the density. In addition, there was a significant positive correlation between predation and instar size, that is, the greater the instar, the greater the predation. Both the total predation and the average predation per head were higher in adults than in nymphs of the 2nd to 5th instar of A. chinensis. As a potential predatory predator, the adult and 4-5 instar nymphs of A. chinensis have strong predatory ability. It is suggested to use the adult and 4-5 instar nymphs of A. chinensis to control the larvae of A. agnata, which can achieve better control effect.
