| 摘 要： | 测定不同发育阶段椰心叶甲的药剂敏感性差异。结果表明，低龄幼虫和成虫对高效氯氰菊酯和阿维菌素的敏感性高于高龄幼虫、蛹和卵。幼虫和成虫对啶虫脒的敏感性高于蛹和卵。卵的药剂敏感性最低。低龄幼虫期为最佳防治适期。椰心叶甲对3种杀虫剂的敏感性大小为高效氯氰菊酯＞阿维菌素＞啶虫脒。随着幼虫的发育，其体重由小变大，对高效氯氰菊酯和啶虫脒的敏感性降低，而幼虫对阿维菌素的敏感性与体重相关不显著。

| Abstract: | The differences of insecticide sensitivities of various developmental stages of Brontispa longissima (Gestro)were studied. The result showed that the insecticide sensitivities of low instar larvae and adults to beta-cypermethrin and avermectin were higher than those of higher instar larvae, pupae and eggs. The insecticide sensitivities of larvae and adults to acetamiprid were higher than those of pupae and eggs. The insecticide sensitivities of eggs were the lowest. The low instar larvae stages were the optimum control period. The susceptibility of B. longissima to 3 kinds of insecticides was the highest to beta-cypermethrin, followed by avermectin and acetamiprid. The insecticide sensitivities to beta-cypermethrin and acetamiprid decreased, as the weight increased from small to large with the development of lavae, however the insecticide sensitivities of larvae to avermectin were not significantly related to weight. |
