中文摘要:羧酸酯酶 (carboxylesterases)的过量产生是库蚊Culexpipiens对有机磷杀虫剂 (OP)产生抗性的主要机制。由est-3和est-2组成的酯酶超级基因座 (estersuper locus)的基因扩增是引起酯酶基因扩增的主要遗传学基础。通过淀粉电泳研究了采自广州、佛山、郑州的库蚊野
英文摘要:Resistance to organophosphate (OP) insecticide in Culex pipiens is caused by over-produced nonspecific esterase. The ester superlocus is one of the m ain genome areas in this resistance, and presents multiple resistance alleles. We study
