摘  要：
草地贪夜蛾Spodoptera frugiperda(J. E. Smith)是2019年新入侵我国的重大农业害虫,已对我国的农作物产生严重为害,筛选、利用本地天敌控制草地贪夜蛾是实现可持续控制的一个重要途径.叉角厉蝽Eocanthecona furcellate(Wolff)是一种广泛分布于热带、亚热带地区的捕食性天敌,是许多鳞翅目、鞘翅目、半翅目害虫的潜在生防因子.本文采用捕食功能反应方法评价了叉角厉蝽对草地贪夜蛾幼虫的捕食效能.研究结果表明,叉角厉蝽3龄、5龄若虫以及雌、雄成虫对草地贪夜蛾3龄及5龄幼虫的捕食功能反应均符合Holling-Ⅱ方程.在饱和猎物密度条件下,叉角厉蝽各虫态对草地贪夜蛾3龄幼虫的平均日最大捕食量依次为32.20头(5龄若虫)>19.40头(雌成虫)>18.20头(雄成虫)>6.60头(3龄若虫),a/Th值(a为瞬时攻击率,Th为处置单头猎物时间)为82.25(5龄若虫)>40.39(雌成虫)>36.12(雄成虫)>17.19(3龄若虫);叉角厉蝽各虫态对草地贪夜蛾5龄幼虫的平均日最大捕食量依次为7.80头(5龄若虫)>6.40头(雌成虫)>5.50头(雄成虫)>4.60头(3龄若虫),a/Th值为11.36(5龄若虫)>10.75(雌成虫)>9.63(雄成虫)>7.45(3龄若虫).本研究表明叉角厉蝽对草地贪夜蛾幼虫具较强的捕食能力,尤其是5龄若虫、雌成虫和雄成虫.研究结果为利用叉角厉蝽防控草地贪夜蛾提供了理论依据,也为其田间释放应用提供技术支撑.

摘  要：
Fall armyworm Spodoptera frugiperda(J. E. Smith) is a dangerous agricultural pest invaded China in 2019, and it has caused serious damage to crops in China. Screening and using local natural enemies to control S. frugiperda is an effective way to achieve sustainable control. The predatory stink bug Eocanthecona furcellata(Wolff)(Hemiptera: Pentatomidae), which is widely distributed in the subtropics and tropics, is a potential biological control agent for lepidopteran, coleopteran, and hemipteran pests. In this paper, the predation efficiency of E. furcellate to the larvae of S. frugiperda was evaluated by the predation functional response method. The results showed that the predation functional responses of the 3~(rd) instar, 5~(th) instar nymphs and female and male adults of E. furcellate to the 3~(rd) and 5~(th) instar larvae of S. frugiperda were fitted with the Holling-II equation. Under the condition of saturated prey density, the number of the 3~(rd) instar larvae of S. frugiperda consumed by E. furcellate were 32.20(5~(th) instar nymph)>19.40(female adult)>18.20(male adult)>6.60(3~(rd) instar nymph), and a/Th value(here a is the instantaneous attack rate, Th is the time used to handle a single prey) were 82.25(5~(th) instar nymph)>40.39(female adult)>36.12(male adult)>17.19(3~(rd) instar nymph), The number of the 5~(th) instar larvae of S. frugiperda consumed by E. furcellate were 7.80(5~(th) instar nymph)>6.40(female adult)>5.50(male adult)>4.60(3~(rd) instar nymph), and a/Th value were 11.36(5~(th) instar nymph)>10.75(female adult)>9.63(male adult)>7.45(3~(rd) instar nymph). This results indicated that E. furcellate had a strong predation capacity against the larvae of S. frugiperda, especially the 5~(th) instar nymphs, female and male adults, which provides the scientific basis and technical support for the application of E. furcellate to control S. frugiperda.
