摘　　要：采用处理液、防腐剂以及吹风3种不同方法对花绒寄甲Dastarcus helophoroides幼虫替代寄主进行接种前表面处理,结果显示,在吹风处理的大麦虫蛹上花绒寄甲成虫羽化率为94%,经处理液和防腐剂处理的大麦虫蛹上的羽化率分别为69%和68.5%;头宽、体长、鞘翅长等指标显示,在吹风处理的大麦虫蛹上羽化出的花绒寄甲成虫与经处理液和防腐剂处理的大麦虫蛹上羽化出的成虫差异显著。吹风法处理替代寄主更适合南方地区繁育花绒寄甲幼虫。The substitute host, Zophobs morio L. , was treated with hair dryer, special fluid and preserva- tive before vaccination. The results showed the emergence rate, head width, body length and elytra length of Dastarcus helophoroides adults were significantly different between hair dryer treatment and the other two treatments. For example ,the emergence rate of adult in the hair dryer treatment was 94% while in the other 2 treatments the emergence rates were 69% and 68.5% respectively. So treating sub- stitute hosts with hair dryer was the most effective method for mass rearing Dastarcus helophoroides in south China.
