目的对现场单独应用S-烯虫酯控制登革热媒介伊蚊的中、英文文献进行系统检索,对其控制效果进行归类分析,并提出相应建议。方法使用“登革热”“S-烯虫酯”“dengue fever”“S-methoprene”等关键词系统检索Web of Science、Embase、Pub...目的对现场单独应用S-烯虫酯控制登革热媒介伊蚊的中、英文文献进行系统检索,对其控制效果进行归类分析,并提出相应建议。方法使用“登革热”“S-烯虫酯”“dengue fever”“S-methoprene”等关键词系统检索Web of Science、Embase、PubMed、中国知网、万方数据服务平台和维普中文科技期刊等数据库。检索时间范围为从1974年1月-2023年1月1日。结果最终纳入10篇文献,其中8项研究被归类为有效性研究,其余2项研究在半现场的环境中探明S-烯虫酯的有效性。筛选结果显示当S-烯虫酯应用于目标容器中的幼蚊时可以产生很好的羽化抑制效果,但在城镇或登革热疫区使用时,能够表明单独使用S-烯虫酯有效性的证据是有限的。结论S-烯虫酯可以在短期内有效减少容器中未发育成熟伊蚊的数量,但目前尚无足够的证据表明单独使用S-烯虫酯可以长期控制登革热媒介伊蚊。有必要进一步研究S-烯虫酯与其他控制登革热媒介伊蚊措施相结合的控制效果。展开更多
