黑箱法与二氧化碳诱捕法蚊虫监测结果比较

目的比较黑箱法和二氧化碳（CO2）诱捕法监测蚊虫密度的差异，探讨黑箱法在蚊虫密度监测中的作用。方法在2个区7个点比较黑箱法和CO2诱捕法监测蚊虫密度、种类的差异，比较2种方法监测蚊种构成比、性别比和季节消长趋势的相关性。结果黑箱法监测蚊虫平均密度为25．63只／箱，是CO2诱捕法平均密度（7．32只／器）的3．50倍，黑箱法监测雌蚊平均密度为14．65只／箱，是CO2诱捕法平均密度（6．23只／器）的2．35倍，2种方法差异有统计学意义，密度指数无相关性；黑箱法捕获蚊种构成，淡色库蚊占捕蚊总数的94．97％，为优势蚊种；白纹伊蚊占4．97％，三带喙库蚊和中华按蚊各仅占0．03％；CO。诱捕法捕获蚊种构成，淡色库蚊占捕蚊总数的79．26％，为优势蚊种；白纹伊蚊占18．27％，三带喙库蚊和中华按蚊分别占2．10％和0．37％，2种监测方法蚊虫构成比差异有统计学意义。结论黑箱法设备简单，易操作，经济成本低，适用范围较广，比较适合淡色库蚊的监测，在淡色库蚊为优势种的地区，可使用黑箱法进行蚊虫密度监测；CO2诱捕法除适合淡色库蚊监测外，还适用于白纹伊蚊监测。

Comparison of mosquito surveillance efficiency between the black box method and carbon dioxide method

Objective To compare mosquito densities using the black box method and the carbon dioxide method and explore the application of the black box approach. Methods The black box method and the carbon dioxide method were used to measure mosquito density and composition at seven locations in two districts of Shanghai. Correlations between species composition, sex ratios and seasonal variation were compared using the two methods. Results The average mosquito density using the black box method (25.63 mosquitoes/box...
