| 摘 要： | 有机磷和氨基甲酸酯类杀虫剂的大量使用导致昆虫对其产生抗药性。乙酰胆碱酯酶是昆虫对这类杀虫剂产生抗性的重要的靶标酶,昆虫产生抗药性的重要原因之一,就是因为乙酰胆碱酯酶的基因表达量上升,或基因突变而导致其敏感性下降。文章简要论述昆虫乙酰胆碱酯酶基因发生变异而导致的抗药性,分析了变异对其结构和功能的影响。 |
| 关 键 词： | 乙酰胆碱酯酶 表达量 点突变 |

| Abstract: | Intensive use of organophosphate and carbamate insecticides led to development of resistance in many insects. Acetylcholinesterase is an important target enzyme to these insecticides. One of the most important reasons for resistance development is acetylcholinesterase increasing expression or point mutation that makes its insensitivity. Here Acetylcholinesterase gene variation conferring insecticides resistance in the pests is summarized briefly and the effects of acetylcholinesterase mutation on its structure and functions were discussed. |
| Keywords: | acetylcholinesterase point mutation increasing expression |
