对樟巢螟的防治力图找到一种既能符合人们当前倡导的无公害生产的要求又能够有效防治障巢螟的农药。五种农药室内及田间药效试验结果表明,8000IU/mg苏云金杆菌可湿性粉剂(高效B.t.)600～1000倍液药后5d平均防效为82.67%,7d仍然达到92.28%,持效期长,但速效性较差。螟虫透叶杀粉剂、25%高效氯氟氰菊酯乳油(劲彪)和52.25%毒死蜱+氯氰菊酯乳油(农地乐)三种化学农药1000～2000倍液药后3d平均防效达到87.03%,7d后仅78.56%,虽然见效较快,但持效期较短。4.5%高氯氰乳油(三步倒)无论是从速效性还是持效性上均不理想。虽然高效Bt速效性较差,但作为微生物杀虫剂具有对人畜安全无毒,易降解、无残留,不污染环境;不会杀伤天敌;不易产生抗性;持效期较长等特点,更适合广泛推广用于防治樟巢螟的危害。
Prevention and treatment of the camphor borer in an attempt to find a can not only meet the current people’s advocacy of pollution-free production requirements and can effectively prevent the barrier pest borer pesticides. The results of five kinds of pesticide indoor and field trials showed that the average control effect of the 8000IU / mg Bacillus thuringiensis wettable powder (high-efficiency Bt) 600 to 1000 times after 5 days of drug treatment was 82.67% and still reached 92.28% after 7 days, But less effective. The average control efficiency reached 87.03% after 1000 to 2000 times of three chemical pesticides, including 25% lambda-cyhalothrin EC (Jinbiao) and 52.25% chlorpyrifos + cypermethrin EC After 7d only 78.56%, although effective, but shorter duration. 4.5% Cyanuric chloride (three-step down) is not ideal for both fast-acting and long-lasting effects. Although high efficiency Bt is less effective, it is safe and harmless to human and animals as a microbial insecticide, it is easy to degrade, has no residue and does not pollute the environment; it will not kill natural enemies; it is not easy to produce resistance; Suitable for the widespread promotion of the damage of the camphor borer.
