小窄径茧蜂林间套笼接蜂试验

Experiment on the release of Agathis pumila in the cage in forest

小窄径茧蜂林间套笼接蜂试验结果表明，影响小窄径茧蜂寿命和林间寄生活动的主要因素是接蜂时间和套笼内温度。７ 月下旬接蜂，寄生率为８．５２％ ～８．９０％ ，７ 月上旬接蜂，寄生率只有１．４０％ ～２．１６％ 。笼内温度超过３０～３４℃，小窄径茧蜂存活时间只有２～４天，少数可存活６～７ 天。在抚顺地区７ 月下旬至８月初是小窄径茧蜂寄生活动的最佳时间。试验表明，小窄径茧蜂可以在我国兴安落叶松鞘蛾上寄生并安全越冬。

The main factors that effect the longevity and oviposition of Agathis pumila are the releasing time and cage temperature.To release in the end of July,the parasitization is 8.52% ～ 8.90% ,while its only 1.40%～2.16% to release in the beginning of July.The average longevity of A.pumila is 3～4 days when temperature in the cage is above 30℃～34℃,and only a few can last 6～7 days.It shows that the best time to release A.pumila is from the end of July to the beginning of August in Fushun area. A.pumila can parasite on Coleophora duhurica and overwinter safely in China.
