孳生地治理对控制白纹伊蚊效果的研究

Evaluation on the control efficacy of source reduction to Aedes albopictus in Shanghai, China

目的观察蚊虫孳生地治理控制白纹伊蚊的效果。方法在试验区共青森林公园游乐区采取各种方法对白纹伊蚊孳生地进行治理;对照区内燃机研究所不采取任何防治措施。实验采用诱蚊诱卵器和CO2诱蚊灯监测白纹伊蚊幼虫和成蚊密度,评价其控制效果。结果在孳生地治理后白纹伊蚊幼虫和成蚊密度逐步下降,在2～3周后幼虫和成蚊相关密度指数皆控制在35以下,密度下降率皆>50%。结论孳生地治理可有效控制白纹伊蚊的密度。

Objective To study the control effect of source reduction to Aedes albopictus population. Methods Various measures were taken to reduce Ae.albopictus breeding sites in the Forest Park, and the Internal Combustion Engine Research Institute was as control without any measures. Mosquito and oviposition trap and CO2 trap were used to evaluate the experiment. Results After source reduction, Ae.albopictus adult and larvae density gradually decreased, and the relative population indexes （RPI） were under 35 and the decline rates of density were more than 50% after treatment for 2 to 3 weeks. Conclusion It was effective to control Ae.albopictus population by source reduction.
