摘 要 ：1986—1990年的研究得知:松毛虫赤眼蜂Tridogramma dendrolimi Matsumura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Dendrolimus punctatus Walker、云南松毛虫Dendrolimus latipennis Walker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。

Abstract:This study was carried out in Zhejiang Province from 1986 to 1990. The results showed that Trichogramma dendrolimi Matsumura began activities in late March and overwintered as pupa in the eggs of Dendrolimus punctatus Walker and D. latipennis Walker during early October to November. The wasp was found in forest the year round and its population peak coincided with the egg period of D. punctatus. The main factors effecting the growth and decline of the population of T. dendrolimi were host egg, honey plant and temperature.
