摘要
本文从桃蚜的生物生态学、抗药性的酶学机理和分子生物学机理三个方面对桃蚜的最近的研究进展作了综述。不同体色的桃蚜对环境的适应能力不同。桃蚜的抗药性主要是由羧酸酯酶 E4扩增引起的。但是乙酰胆碱酯酶的不敏感性也增加了桃蚜对氨基甲酸酯类农药的抗性。在分子水平上 ,桃蚜的抗性机制主要是酯酶基因的扩增。同时对这些扩增的酯酶基因的遗传方式也有一些研究。
This paper reviews the recent researching development of Myzus persicae from the biology and ecology , esterase mechanism and molecular biology mechanism et. three aspects. The adapting ability of different color-forms vary widely. The resistance of green peach aphids to insecticides results mainly from the enhance the levels of the E4 carboxylesterase. Besides ,the marked insensitivity of acetylcholinesterase to insecticide enhanced the resistance of Myzus Persicae(Sulzer) to carbamate. At the molecular biology level, esterase gene amplification is the main reason for the insecticide resistance of Myzus persicae. The inheritance of the amplified esterase genes has also been studied.
