本研究得到如下结果:1.瓢虫与球蜡蚧的生潘史相配合,在春季、初夏和秋季瓢虫对球蜡蚧均有控制作用。2.瓢虫幼虫的4个龄态和成虫的3个阶段对球蜡蚧密度的功能反应均属HollingⅡ型,捕食量逐龄递增,4龄幼虫的捕食量最高。幼虫的发育历期随球蜡蚧密度的增加而缩短,发育速率加快。3.在干扰法效果测定中,除去瓢虫和保留瓢虫的两种处理,球蜡蚧种群趋势指数1分别为1.474和0.0029,其Ⅰ值之比为105:1。
The results obtained in this study are as follows: 1. The ladybugs are closely related to the perennials of Panax notoginseng in the spring, early summer and autumn. The functional response of the ladybug larvae in four stages and three stages of adults to Holocene larvae showed Holling type Ⅱ. The predation amount increased gradually and the predation amount of 4th instar larvae was the highest. The developmental duration of larvae was shortened with the increase of M. dendrolimi density, and the developmental rate accelerated. In the interference effect test, except for ladybugs and ladybugs, the trend index 1 of A. coccacia population was 1.474 and 0.0029, respectively, and the ratio of Ⅰ values was 105: 1.
