朝鲜紫姬蜂(Chlorocryptus coreanus SzePligeti)是黄刺蛾幼虫及蛹期的主要寄生蜂,据辽中县茨于坨公社太平村林场测报点1979年调查,苹果梨树上的黄刺蛾茧内寄生率达60％,三年生的杨树林中的茧内寄生率达81％,控制了黄刺蛾的大发生。因此是一种有利用前途的天敌,朝鲜紫姬蜂不仅在辽中县内寄生大量黄刺蛾幼虫和蛹,在海城、台安、黑山也有寄生。寄生率高,利用它防治黄刺蛾是很有前途的。我们于1977～1979进行了三年的观察,现将结果分述如下:
Chlorocryptus coreanus SzePligeti is the main parasitic wasp of larvae and pupal stage of Trichoplusia latifolia. According to the survey of 1979 in Taiping village, Rate of 60%, three-year-old poplar in the cocoon parasitic rate of 81%, controlling the occurrence of yellow thorn moth. Therefore, it is a predatory natural enemy. Aster symphysus not only parasitizes a large number of larvae and pupae in Liaozhong County, but also parasites in Haicheng, Taian and Montenegro. The parasitism rate is high, it is very promising to use it to control the sting moth. We conducted a three-year observation from 1977 to 1979 and now we summarize the results as follows:
