摘要
为了明确肉桂双瓣卷蛾对樟树的危害情况并筛选出防治该虫的环境友好型杀虫剂,作者采用标准地调查以及室外药剂防治试验的方法,进行了肉桂双瓣卷蛾对樟树的危害情况调查及不同杀虫剂对该虫的药剂防治试验。危害情况调查结果表明,樟树株被害率平均为92.9%、嫩梢枯梢率平均达76.6%,危害非常严重。8种药剂防治肉桂双瓣卷蛾结果表明,5%氯虫苯甲酰胺悬浮剂、16%虫线清乳油、40%氯虫·噻虫嗪水分散剂和8 000U/mL苏云金杆菌悬浮剂的防治效果均能达到90%以上,22%噻虫·高氯氟微囊悬浮剂的防治效果接近90%,因此建议在生产上,轮换使用以上杀虫剂。
Sample plot investigation and outdoor chemical control tests were carried out to evaluate the hazards of Polylopha cassiicola on Cinnamomum camphora and screen out the environment-friendly pesticides against P. cassiicola. The results showed that the damaged rate and dieback rate of tender tip of C. camphora caused by P. cassiicola were 92.9 %and 76. 6 %, respectively. Among 8 tested insecticides, the control effects of 5% chlorantraniliprole SC, 16% chongxianqing EC, 40O//oo chlorantraniliprole thiamethoxam AS,and 8 000 U/mL Bacillus thuringiensis SC were all higher than 90% and the control effect of 22% thiamethoxam · lambda-cyhalothrin SC was 88. 9%. It is recommended that these 5 insecticides can be used alternately in P. cassiicola control.
