摘要: 为明确蠋蝽对黏虫的捕食能力,在试验条件下进行蠋蝽3龄、5龄若虫以及雌成虫分别对黏虫3龄,5龄幼虫的捕食试验,将各龄期蠋蝽饥饿24 h后投放不同密度黏虫,采用HollingⅡ功能模型拟合数据明确其控害效能。结果显示蠋蝽3龄、5龄若虫和雌成虫对黏虫3龄、5龄幼虫的捕食功能反应都符合HollongⅡ模型;各龄期蠋蝽对3龄黏虫瞬时攻击率由高到低为3龄若虫(0.621),雌成虫(0.576),5龄若虫(0.568);蠋蝽雌成虫(14.40)的控害效应最高。各龄期蠋蝽对5龄黏虫的瞬时攻击率由高到低为雌成虫(0.778),5龄若虫(0.475),3龄若虫(0.365);蠋蝽雌成虫(7.14)的控害效应最高。随着黏虫密度增大,蠋蝽的搜寻效应逐渐降低,雌成虫的搜寻效应明显大于其他虫态。本研究显示,蠋蝽对黏虫具有较大的控害能力,在利用蠋蝽对黏虫进行生物防治时,选用雌成虫效果最佳。

Abstract: The predation capacity of Arma chinensis on Mythimna separate (Walker) was determined by measuring the predation of the 3rdand 5th instar nymphs and the female adults of A. chinensis starved for 24 hours on the 3rd and 5thM. separata instars at different densities. The results showed that the 3rd and 5th instar nymphs and female adults of the predator exhibited Holling II functional responses. The attacking efficiency of the predators to the 3rd instar M. separate larvae ranked from high to low was the 3rd instar nymphs (0.621), female adults (0.576), and the 5th instar nymphs (0.568); the female adults had the highest control efficiency (14.40). The attacking efficiency of A. chinensis to the 5th instar M. separate larvae ranked from high to low was female adults (0.778), the 5th instar nymphs (0.475), and the 3rdinstar nymphs (0.365); the female adults had the highest control efficiency (7.14). With the increase of prey density, predators’ searching efficiency decreased gradually, and the searching efficiency of females was obviously higher than those of the other stages. The results show that A. chinensis has great control ability to M. separate, especially the female adults.

Key words: Arma chinensis, mythimna separate, predation functional responses
