摘要：微红梢斑螟Dioryctria rubella和果梢斑螟D. pryeri是我国马尾松、油松、黄山松和华山松等松树的重要钻梢蛀果害虫,引起梢枯干折,树冠畸形,果空籽瘪,严重影响松树的生长和成材,并造成种子园种子产量歉收。林间害虫种群观测和室内害虫饲育发现长距茧蜂Macrocentrus sp.(膜翅目、茧蜂科Bracodidae)是这两种松梢斑螟的重要寄生昆虫,种群数量较多,繁殖较强。该蜂幼虫寄生两种松梢斑螟幼虫体内。林间,微红梢斑螟越冬代幼虫寄生率为9.2％;果梢斑螟第一代幼虫寄生率为7.8％。在两种松梢斑螟幼虫种群数量增长中,该蜂起重要的制约作用。
Macrocentrus sp. usually appears two generations in a year in Zhejiang Province. The adult periods occur in late April to late May, July and late September to mid-October. The sex ratio of wintering generation was shown to be 1.0:1.6(male:female). The test of the contact toxicity of three insecticides showed that these insecticides were highly harmful to the adult of the parasite, and should be Prohibited to be used during the adult stage in the field.
