摘　　要：用3 75%灭幼脲Ⅲ号油剂防治樟子松蠹象幼虫,杀虫率达94 75%;用15%灭幼脲Ⅲ号油剂处理成虫,可使雌虫产卵量降低43 3%～61 4%,卵孵化率降为0。用该种方法处理饵木,6月份饵木不需要剥皮处理,可提高饵木使用价值。controlling experiment of Pissodes validirostris by Chlorbenzuron shows following results: which could kill 94.75% larvae using 3.75% concentration; egg-laying quantity decrease by 43.3%～61.4% using 15% concentration and incubation rate reduce to zero for the female insects. If this method was adopted in the trap logs without barking in June,it would enhance their value in use.
