摘要
新烟碱类杀虫剂是一类新开发的杀虫剂。研究表明,害虫野外种群对其敏感性差异较大,现已有多种害虫对吡虫啉和啶虫脒产生了抗性。初步研究显示,马铃薯叶甲对吡虫啉抗性以不完全隐性的常染色体遗传;抗性似不稳定,交互抗性谱随虫种而变化,抗性形成可能与多功能氧化酶和酯酶有关。合理轮用和高剂量杀死策略是治理其抗性的有效措施。
Chloronicotinyl insecticides is a group of new developed insecticides. The survey results indicated that the greater differences of susceptibility to these insecticides existed in different insect populations. Several insect pests have evolved the resistance to imidacloprid and acetamiprid now. The resistance of Colorado potato beetle, Leptinotarsa decemlineata, to imidacloprid was inherited autosomaly as an incompletely recessive factor. The pest resistance to chloronicotinyl insecticides seems unstable. The cross-resistance spectrum changed in accordance with the pest species. The mixed-function oxidase and esterase were probably involved in the evolution of pest resistance to chloronicotinyl insecticides. The rational rotation of insecticides and the high doses may be effective resistance management strategies for this class of insecticides.
