| 摘 要： | 为了探索杀虫剂防治椰心叶甲的策略,采用林间小区试验在椰子树和大王椰中分别研究挂包和打孔两种不同施药方法对椰心叶甲防效的影响。结果表明,挂包法对椰子树和大王椰上的椰心叶甲具有优秀的防治效果,药后30d的防效达95%以上;打孔施药法对大王椰上的椰心叶甲具有优秀的防治效果,药后30d防效达90%以上,而对椰子树上的椰心叶甲防效不理想。 |
| 关 键 词： | 挂包法 打孔注药法 椰心叶甲 防效 |

| Abstract: | To explore a new insecticide-based controlling strategy for Brontispa longissima, we designed field plot experiments in Cocos nucifera and Roystonea regia to investigate the effects of hung bag and trunk injection. In the experiment region, the effect of hung bag in Cocos nucifera and Roystonea regia more than 95%, trunk injection in Roystonea regia more than 90%, after 30 days. But the effect of trunk injection in Cocos nucifera was unsatisfactory. |
| Keywords: | hung bag trunk injection Brontispa longissima (Gestro) control effect |
