摘　　要：利用花绒寄甲(Dastarcus helophoroides)防治锈色粒肩天牛(Apriona swainsoni)试验,结果表明:花绒寄甲对锈色粒肩天牛的寄生率可达68%,而且寄生率随着释放量的增加而提高,按锈色粒肩天牛幼虫与花绒寄甲卵数量之比为1∶20、1∶80和1∶150的比例分别释放,其校正寄生率分别为37.36%、64.69%和67.00%,考虑到防治成本,最佳释放比例应为1∶80;最佳释放时间为4月下旬和8月下旬。The experiment of controlling Apr/ona swainsoni by Dastareus helophoroides was studied. The results showed that the con- trol effect was 68%, the parasitical death rote ofDastarcus helophoroides raised with the increasing of touching Dastarcus hdophoroides, and touched with 1：20, 1：80 and 1：150, the ratios of amounts to Dastareus helophoroides amounts, the parastizing infecting death rotes were37.36 % ,64.69 % and 67.00 % respectively, Think that cost,the best release proportion to prevention and cure should be 1：80; The best release time is the last ten-day period of a month in April and goes down ten-day periods August.
