两种成蚊监测工具现场捕蚊效果比较研究

Comparative study on mosquito trapping efficacy between two mosquito trapping lamps

目的比较研究CO2诱蚊灯和光诱诱蚊灯现场捕蚊效果,为成蚊的合理监测提供依据。方法 2018年8-10月,随机选取青岛市不同生境,同时采用CO2诱蚊灯和光诱诱蚊灯进行成蚊监测,收集捕获成蚊并进行分类统计。蚊虫密度比较采用Mann-Whitney秩和检验,构成比比较采用χ2检验。结果 2种诱蚊灯均能诱捕蚊虫,CO2诱蚊灯监测蚊密度为25.00只/(灯·夜),明显高于光诱诱蚊灯的4.50只/(灯·夜),差异有统计学意义(Z=-2.915,P=0.004);CO2诱蚊灯监测的蚊科构成比(94.90%)和雌蚊构成比(99.68%)均高于光诱诱蚊灯(11.94%和77.27%),差异有统计学意义(χ2=2 268.789,P=0.000;χ2=315.951,P=0.000);2种诱蚊灯捕获的蚊种构成比之间差异有统计学意义(χ2=18.903,P=0.000)。结论 2种诱蚊灯均可用于成蚊监测,研究者可根据研究目的合理选择1种或2种监测工具,全面分析监测地成蚊密度、种群和季节消长趋势。

Objective To compare the efficacy of mosquito trapping between CO2 and light trapping lamps and to provide a basis for effective mosquito surveillance.Methods From August to October,2018,different habitats in Qingdao were randomly selected,CO2 and light trapping lamps were simultaneously used for mosquito surveillance,and captured adult mosquitoes were collected and classified.The Mann-Whitney U test was used to compare the mosquito density,and theχ2 test was used to compare the proportion of mosquito species.Results Both trapping lamps were able to trap mosquitoes,and the mosquito density determined by CO2 trapping lamp(25.00/lamp·night)was significantly higher than that determined by light trapping lamp(4.50/lamp·night)(Z=-2.915,P=0.004).The proportions of mosquitoes and female mosquitoes captured by CO2 trapping lamp(94.90%and 99.68%)were significantly higher than the proportions of those captured by light trapping lamp(11.94%and 77.27%)(χ2=2 268.789,P=0.000;χ2=315.951,P=0.000),and the mosquito species compositions captured by the two mosquito trapping lamps were significantly different(χ2=18.903,P=0.000).Conclusion Both CO2 and light trapping lamps can be used for mosquito surveillance,and researchers can choose one or more surveillance tools according to the study objective to comprehensively analyze and survey the density,population,and seasonal variation of adult mosquitoes.
