| 摘 要： | 在南京几个公园的柳树上释放花绒寄甲以防治光肩星天牛,定期测定防治效果及寄生状况.结果表明：释放花绒寄甲对当年和翌年的光肩星天牛均能达到控制效果;1个月后树体上的花绒寄甲校正寄生率达到35％左右,虫口校正减退率在45％左右;翌年花绒寄甲在光肩星天牛上的寄生率均值接近37％;花绒寄甲可以在供试的光肩星天牛（寄生率67％）和大麦虫（寄生率85％）的蛹体上完成寄生生活,而不能寄生家蚕.

| Abstract: | Dastarcus helophoroides was released on willow trees in some parks of Nanjing City to parasitize on and to control Anoplophora glabripennis that severely harmed the willow trees, the parasitic rate and control effect were periodically determined. The results showed that the release of Dastarcus helophoroides could effectively control Anoplophora glabripennis both in the first and second year. The corrected parasitic rate of Dastarcus helophoroides could reach 35 % one month after releasing in willow trees, and the corrected decline rate of Anoplophora glabripen- his pest population was about 45 %. The average parasitic rate Of Dastarcus helophoroides on Anoplophora glabripenhis was around 37% in the second year. The study showed that Dastarcus helophoroides could parasitize on pupa of both Anoplophora glabripennis （with 67 % of parasitic rate） and Zophobas morio （with 85 % of parasitic rate）, but it could not parasitize on Bombyx mori pupa. |
