摘要: 为了评估益蝽成虫对草地贪夜蛾不同龄期幼虫的捕食潜力,本试验在室内条件下开展了益蝽雌性和雄性成虫对草地贪夜蛾3、4、5龄幼虫的捕食能力试验。结果表明:益蝽雌性和雄性成虫对草地贪夜蛾3、4、5龄幼虫的捕食功能反应均符合HollingⅡ模型,雌性成虫对草地贪夜蛾3、4、5龄的日最大捕食量分别为61.013、30.057、10.251头;瞬时攻击率分别为1.093、1.441、0.964;处理时间分别为0.384、0.792、2.352 h。雄性成虫对草地贪夜蛾3、4、5龄的日最大捕食量分别为58.824、24.522、9.302头;瞬时攻击率分别为0.996、1.365、1.210;处理时间分别为0.408、0.984、3.072 h。益蝽成虫对草地贪夜蛾3、4、5龄幼虫都能捕食,对3龄幼虫捕食量最大,最喜欢捕食4~5龄幼虫,对4龄幼虫的瞬时攻击率最高,益蝽对草地贪夜蛾具有较好的捕食能力,为草地贪夜蛾的可持续防控提供了新的方法和依据。

Abstract: In order to investigate the predation potential of Picromerus lewisi (Fallou) on Spodoptera frugiperda (J. E. Smith), the ability of P. lewisi adults to predate on the 3rd, 4th and 5th instar larvae of S. frugiperda was studied under laboratory conditions. The results showed that the maximum daily predation amounts of female adults on the 3rd, 4th and 5th instar larvae were 61.013, 30.051 and 10.251, respectively. The attacking efficiencies were 1.093, 1.441 and 0.964, respectively. The treatment times were 0.384, 0.792 and 2.352 h, respectively. The maximum daily preys consumed by the male adults on the 3rd, 4th and 5th instar larvae were 58.824, 24.522 and 9.302, respectively. The attacking efficiencies were 0.996, 1.365 and 1.2107, respectively. The treatment times were 0.408, 0.984 and 3.072 h, respectively. The predation of P. lewisi adults on the 3rd instar larvae of S. frugiperda was the largest, and the predator also preferred the 4th and 5th instar larvae. The attacking efficiencies of both male and female adults against the 4th instar larvae were the highest. The results indicate that P. lewisi has good control potential on S. frugiperda and can be used for the prevention and control of S. frugiperda.
