摘　　要：目的通过在大型居民区开展蚊虫诱集试验,比较3种化学引诱剂(引诱剂A、B、C)、CO_(2)与引诱剂组合对常见蚊虫的诱集效果,为化学引诱剂与CO_(2)在蚊虫监测与防制现场的应用提供科学依据。方法3种引诱剂连续10 d诱集野外蚊虫,分析逐日诱集能力;采用拉丁方设计、交叉试验方法,分别进行引诱剂、引诱剂联合150 ml/min流量CO_(2)诱集蚊虫试验,进行方差分析和秩和检验,分析引诱剂和CO_(2)对蚊虫的诱集效果,以及CO_(2)对引诱剂诱集蚊虫种类、性别的影响。结果引诱剂A、B、C连续10 d平均诱集蚊虫分别为220.00、203.67和16.67只,每日最高诱捕数分别为46、49和5只;引诱剂A、双份引诱剂A、引诱剂A联合150 ml/min流量CO_(2)分别诱集蚊虫358、784和1268只,三组间诱集数量两两比较差异均有统计学意义(均P<0.05);引诱剂A、B各自联合150 ml/min流量CO_(2)增强了诱蚊效果,与引诱剂A、B单独使用对致倦库蚊和白纹伊蚊及其雌蚊和雄蚊的诱集差异均有统计学意义(均P<0.001)。结论化学引诱剂A、B在野外环境诱捕蚊虫具有一定的持效性,联合CO_(2)的增效比提高引诱剂份量更强,可应用于蚊虫监测与防制工作。Objective To compare the effectiveness of three chemical attractants(A,B,and C)and carbon dioxide(CO_(2))as well as their combinations in attracting and trapping common mosquitos by conducting experiments in large residential areas,so as to provide a scientific basis for the application of chemical attractants and CO_(2)in mosquito surveillance and control.Methods Mosquito attracting and trapping experiments were conducted in the field using three attractants over 10 consecutive days.The mosquito attracting and trapping abilities were analyzed for each day.Experiments with the attractants and combination of the attractants and 150 ml/min flow CO_(2)were conducted using Latin square design and cross-over method.Analysis of variance and rank sum test were performed to evaluate the effectiveness of the attractants and CO_(2)in mosquito attracting and trapping,as well as the impact of CO_(2)on the species and sex of mosquitos attracted and trapped.Results The average numbers of mosquitos attracted and trapped by attractants A,B,and C over 10 consecutive days were 220.00,203.67,and 16.67,respectively,with the maximum number being 46,49,and 5 per day,respectively.Attractant A,double attractant A,and attractant A combined with 150 ml/min flow CO_(2)attracted and trapped 358,784,and 1268 mosquitos,respectively,with significant differences in any two of the three groups(all P<0.05).Attractants A and B combined with 150 ml/min flow CO_(2)respectively enhanced the effectiveness of attracting mosquitos,with significant differences observed in Culex pipiens quinquefasciatus and Aedes albopictus(all P<0.001)and between the female and male mosquitoes of them(all P<0.001).Conclusions Chemical attractants have a certain lasting effect in trapping mosquitos in the field.The combination of attractants with CO_(2)can enhance the trapping effect more significantly than increasing the portion of attractants,making them applicable in mosquito surveillance and control.
