摘要
以城市行道树垂柳为对象,试验研究了释放花绒寄甲4～8a后对光肩星天牛的控制效果,结果表明,与未释放的对照林相比,释放花绒寄甲4～8a后可将光肩星天牛的危害株率由100%控制于23.46%,株均幼虫数由5头控制于2头;释放年份不同控制效果虽有差异,但差异不明显;释放花绒寄甲能够持续有效降低树木的受害株率、降低光肩星天牛幼虫数量。
Dastareus helophoroides at 4～8 a were released for the control of Anoplophora glabripennis （Motschulsky） attacking street willows. The result showed that the infected rate of was reduced dra matically from 100% to 23.46%. The number of larvae per plant dropped from 5 to 2 heads. Releasing in different year caused different effect, but not significant.
