摘要

摘要:作为人类疾病的重要媒介,突尼斯库蚊种群对有机磷杀虫剂产生了耐药性。为了了解这种抗性的起源,需要了解对农业病虫害防治活动的影响及其对抗性机制的意义。在突尼斯各地具有不同农业病虫害和蚊虫控制活动的不同地点采集了五个库蚊种群,并测试了它们对杀硝基苯的抗性水平。将结果与未进行化学活动的对照人群的结果进行比较。我们的研究结果强烈表明,尽管研究地点的数量相当有限(五个种群),但农药产品和记录的抗性之间存在相关性。另一方面,有机磷的控制活性使我们认为存在对杀硝基硫磷抗性的重要影响。然而,拟除虫菊酯类杀虫剂的施用似乎对杀硝基苯(有机磷)的抗性几乎没有影响。对照种群记录的抗性应是人为因素造成的;然而,还应考虑迁移和基因流动对杀虫剂抗性进化的综合影响。记录的抗性是由酶解毒和靶位点敏感性介导的。我们的研究结果表明,代谢和靶位点耐药性与耐药性水平呈正相关。总之,我们可以说,突尼斯农业和公共卫生部门对杀虫剂和杀虫剂的使用应该更加合理,以减少库蚊种群的耐药性发展。

The Contribution of Irrational Use of Chemical Products to Increasing Fenitrothion Resistance in Tunisian Populations of Culex pipiens pipiens (Diptera: Culicidae)
ABSTRACT: Tunisian populations of Culex pipiens pipiens, an important vector of human diseases, have developed resistance to organophosphate insecticides. To understand the origin of this resistance, knowledge of the impact on agricultural pest and mosquito control activities and its significance for the resistance mechanisms will be required. Five populations of C. p. pipiens were collected at various sites with different agricultural pest and mosquito control activities throughout Tunisia and tested for fenitrothion resistance level. Results were compared to those obtained from a control population where no chemical activities have been carried out. Our results strongly suggest the presence of a correlation between agrochemical products and the recorded resistance despite a rather limited number of studied sites (five populations). On the other hand, organophosphates control activities let us suggest the existence of an important impact on fenitrothion resistance. However, it appears that the application of pyrethroids have little to no impact on fenitrothion (organophosphate) resistance. The recorded resistance of the control population should be due to anthropogenic factors; however, the combined effect of migration and gene flow on the evolution of insecticide resistance should also be taken into consideration. The recorded resistance was mediated by both enzymatic detoxification and target-site sensitivity. Our findings showed a positive correlation between both metabolic and target site resistance and the level of resistance. In conclusions, we can say that the use of pesticides and insecticides by both agricultural and public health departments in Tunisia should be more rationalized to reduce the development of resistance in C. p. pipiens populations.
