| 摘 要： | 白跗平腹小蜂在浙江于4月中下旬自然羽化,10月上旬在第3代马尾松毛虫卵中,n月在柳杉毛虫卵中, 以老熟幼虫越冬, 翌年4月中下旬开始羽化活动。在自然温度下, 用柞蚕剖腹卵繁殖, 年发生6~7世代。在林间的年周期活动中, 其种群数量分别在5-6月和9-10月出现两次高峰。这和马尾松毛虫、柳杉毛虫、水青蛾、大背天峨和油茶枯叶峨等主要森林害虫的卵期吻合。该蜂对它们的抑制力分别是16.55%~22.90%, 23.45%, 2.63%~5.49%,1.97%和3.00%~7.00%。该蜂在林间的水平扩散距离达32m以上。

| Abstract: | Anastatus albirarsisnaturally incubates in the middle and late April in Zhejiang Province. Its mature larvae overwiter in eggs of the third generationDendrolimus puntatuse in early October, in eggs of Dendrolimus latipenuis in November. Under natural temperature, there are 6~7 generations each year. There are two peaks of population which occur from May to June and from September to October respectively. The peak time coincides with the egg season of main forest inscets such asDendrolimus puntatuse, Dendrolimus latipenuis, Actias seleneningpoana, Meganoton analis and Lebeda nobilis, and its controling rate to above insects are 16.55%~22.9%, 23.45%, 2.63%~5.40%, 19.50% and 3.00%~7.00% respcetively. The wasp can spread more than 32 meters of level distance in the forest. |
