杀虫剂对控制人类疾病的主要传播媒介起着重要的作用.由于长期使用卫生杀虫剂及农药,导致了蚊虫产生了抗药性,这不仅增加了农药的使用量和防治次数,也大大增加了防治费用和成本,大量杀虫剂的使用更加速了蚊虫抗性的增强,如此恶性循环,最终结果将会越来越糟糕.抗药性问题的出现和加剧不仅缩短了当前正在使用的杀虫剂的寿命,而且由于交叉抗性和抗性机制的多元化,新开发的杀虫剂的功效和使用寿命也被大大降低.本实验分别用仲丁威、高效氯氰菊酯、氯菊酯、残杀威、胺菊酯、对硫磷、溴氰菊酯、毒死蜱和敌敌畏等9种不同农药,配制成不同浓度梯度,按照Raymond,Marquine（1994）等的方法对三里畈种群进行蚊虫幼虫生物测定,结果其抗性分别是敏感体系S-lab的2.4倍、5.9倍、2.7倍、3.8倍、3.2倍、2.5倍、15.4倍、65.7倍和43.8倍.反应终点法测酯酶活性OD值计算酯酶含量,结果平均吸光度三里畈种群是敏感体系S-lab的2.28倍,抗性比率为11倍.联系实际发现,此结果与人们使用农药杀虫剂的时间长短、频率及使用量的多少呈正相关.而蚊虫抗性的机理等的问题还有待深入研究.

Pesticides to control the main media human diseases plays an important role. Due to long-term use health pesticides and chemicals, leading to the mosquito developed resistance, it not only increased pesticide use and prevention of times, has greatly increased control expenses and costs, a lot of pesticide use more accelerated the mosquito resistance increases, so vicious circle, final results will be getting worse.Drug-resistant problem arises and aggravate the currently used not only shorten the life of the pesticides, and due to resistance and resistance mechanism of crossing the development of new pesticides pluralism, the efficacy and service life also been significantly reduced.This experiment respectively with ZhongDingWei, beta-cypermethrin, permethrin, slay, wei, amine chrysanthemum esters, DuiLiuLin, deltamethrin, chlorpyrifos and LDC 9 different pesticides, made into different concentration gradients, Raymond, according to Marquine (1994) method for mosquito larvae population mile miles of the resistant, biometric results were sensitive system S - lab 2.4 times, 5.9 times, 2.7 times, 3.8 times, 3.2 times, 2.5 times, 15.4 times, 43.8 times 65.7 times .Reaction end approach to measure ester enzyme activity OD value are calculated esterase was the average absorbance of the amount of the population is sensitive system miles sp6 lab (S) - the resistance ratio to 2.28 times, 11 times. With practice, this result and found people use pesticides time length, frequency and use many were positively correlated. And the mechanism of mosquitoes resistance problems still remain to be further addressed.
