Abstract

Abstract: Objective To investigate the efficacy of three mosquito attractants (Attractant A, B, and C), carbon dioxide (CO₂) at different flow rates and attractant combined with CO₂in attracting Aedes albopictus, to screen out the optimal combination, and to provide a scientific basis for the application of chemical pheromone monitor in the field work of Ae. albopictus surveillance. Methods A remote-controlled chemical pheromone mosquito trap monitor was used to perform the trapping test. A total of 200 Ae. albopictus mosquitoes were placed in the simulation room, and the trapping test was conducted for the three mosquito attractants, CO₂ at different flow rates, and attractant combined with CO₂, and efficacy was observed after 24 hours. The Chi-square test and the logistic regression analysis were used to compare and analyze the efficacy of different attractants and CO₂ flow rates in trapping Ae. albopictus. Results CO₂ at a flow rate of 80, 150, and 200 ml/min had mean trapping rates of 50.42%, 64.67%, and 74.33%, respectively, and attractant A, B, and C had mean trapping rates of 66.40%, 70.30%, and 53.00%, respectively. Attractant A combined with CO₂ at a flow rate of 80, 150, and 200 ml/min had mean trapping rates of 66.67%, 67.33%, and 79.67%, respectively, and attractant B combined with CO₂ at a flow rate of 80, 150, and 200 ml/min had mean trapping rates of 70.67%, 78.67%, and 82.33%, respectively. Conclusion In the simulation test, the remote-controlled chemical pheromone mosquito trap monitor with the application of mosquito attractant and CO₂ has a marked effect in trapping Ae. albopictus, which is better than the use of attractant or CO₂ alone. The surveillance method can be used for field surveillance and control of vector Aedes mosquitoes.

摘要： 目的通过模拟试验测试3种蚊虫引诱剂（诱思达引诱剂A、B、C）、不同流量CO₂及其组合诱集白纹伊蚊的效果，筛选出最优的组合，为化学信息素监测仪在媒介伊蚊监测现场的应用提供科学依据。方法用远程控制化学信息素诱蚊监测仪进行诱集试验，在模拟室投放200只白纹伊蚊，分别进行3种蚊虫引诱剂、不同流量CO₂、引诱剂与不同流量CO₂组合对媒介伊蚊的诱集试验，24 h后观察结果。采用χ²检验和logistic回归统计方法，比较分析不同引诱剂、不同流量CO₂对白纹伊蚊的诱集效果。结果 CO₂流量为80、150和200 ml/min的平均诱集率分别为50.42%、64.67%和74.33%，引诱剂A、B、C的平均诱集率分别为66.40%、70.30%和53.00%。引诱剂A与流量为80、150和200 ml/min的CO₂组合诱集率分别为66.67%、67.33%和79.67%，引诱剂B与流量为80、150和200 ml/min的CO₂组合诱集率分别为70.67%、78.67%和82.33%。结论在模拟试验中，远程控制化学信息素诱蚊监测仪组合蚊虫引诱剂与CO₂，对白纹伊蚊的诱集效果明显，优于单独使用引诱剂或者CO₂。该监测方法可用于媒介伊蚊的现场监测与防治。
