1986—1990年的研究得知:松毛虫赤眼蜂TridogrammadendrolimiMatsumura在浙江于3月下旬开始活动,10月上旬至11月陆续以蛹在马尾松毛虫DendrolimuspunctatusWalker、云南松毛虫DendrolimuslatipennisWalker等虫卵中越冬在林中常年都可见到该蜂的活动,其种群数量出现的高峰期与松毛虫卵期相一致。林中昆虫卵的多少、蜜源植物的有无、温度的高低,是影响松毛虫赤眼蜂林间种群消长的主要因子。
From 1986 to 1990, it was learned that Tridogrammadendrolimi Matsumura started its activities in late March in Zhejiang Province. From the beginning of October to November, it gradually became pupae to win over the eggs of Dendrolimus punctatus Walker and Dendrolimus latipennis Walker in Dendrolimus latipennis Walker, The activity of the bee can be seen in perennial perennials, and the peak of its population size coincides with that of the pine caterpillar. The number of insect eggs in the forest, the presence or absence of nectar plants, and the level of temperature are the major factors that affect the population growth and decline among the Trichomus troglodytes.
