麦蛾茧蜂是仓库害虫粉斑螟等幼虫的天敌。在温州,一年发生13—14代该蜂生活周期短,7—8天可繁殖一代,成蜂寿命长(233.5天),繁殖量大,单雌最多能繁殖276只幼蜂。成虫与蛹能耐低温,在4—8℃下,可保存1个月。成蜂能攻击深层粮堆内的寄主,一般寄生率78.7—91.6％。放蜂期间可掌握在仓虫发蛾高峰后10～15天,根据试验结果,认为此蜂有利用价值。

Callicarpa is a natural enemy of the larvae of the warehouse pest, In Wenzhou, 13-14 generations a year have a short life cycle, 7-8 days to reproduce a generation, adult bee long life (233.5 days), breeding large, single female can reproduce up to 276 juveniles. Adult and pupae can tolerate low temperature, at 4-8 ℃, can be stored for 1 month. As bees can attack the host of deep grain piles, the general parasitic rate of 78.7-91.6%. During the beekeeping, it can be controlled 10 to 15 days after the peak of the houseworm moth. According to the test results, it is considered that the bee has the value of utilization.
