摘　　要：为给宝鸡市防治日趋严重的天牛危害提供参考和依据,在受害严重的扶风县、陈仓区、眉县选择受害重度和中度的9个有代表性的地段,进行释放花绒寄甲生物防治试验,结果为释放花绒寄甲后9个样地的天牛危害程度都下降为轻度,原来受害严重的4个样地平均株虫口减退率为58.9%,原来受害程度中度的5个样地平均株虫口减退率为52.4%,释放花绒寄甲可以有效控制天牛虫口密度和危害程度。该方法可在宝鸡市大面积推广。To control of Longicorn beetles with biological manners in Baoji, Dastarcus helophoroides were released at nine serious places of extreme severity and moderate severity distributed in Fufeng County, Chencang District and Meixian County. The result showed that the severity of damage in these nine places have been alleviated to mild degree, with pest number in 4 most serious places reduced to 58.9%, and pest number in 5 moderately serious places reduced to 52.4%. Release of Dastarcus helophoroides can effectively control long-horned beetles.
