目的评估MT-1二氧化碳(CO_2))诱蚊器诱捕白纹伊蚊的效果。方法采用析因设计方案,设6个CO_2流量组和1个CO_2空白对照组、10个监测时段和7个取样点,在每个取样点布放诱蚊灯,每2 h调整诱蚊器的CO_2流量并更换捕蚊笼,将采集到的蚊虫分类并计数,监测时间为02:00-22:00,探讨CO_2流量、监测时段和取样点对MT-1 CO_2诱蚊器诱捕白纹伊蚊效果的影响。结果 (1)共捕获蚊类1122只,其中白纹伊蚊占83.69%;(2)CO_2流量组对白纹伊蚊的诱捕效果高于对照组(F=3.05,P=0.01),流量为6 L/min时捕获的白纹伊蚊最多;(3)不同监测时段对白纹伊蚊捕获数量的影响差异有统计学意义(F=2.98,P=0.03),18:00-20:00和04:00-06:00两个时段捕获的白纹伊蚊数量较多;(4)各取样点捕获的白纹伊蚊差异无统计学意义(F=0.47,P=0.80)。结论 MT-1 CO_2诱蚊器对白纹伊蚊有诱捕效果,可用于监测白纹伊蚊;建议在傍晚时挂灯,CO_2流量设置为6L/min。
Objective To assess the efficacy of MT-1 carbon dioxide (CO_2) trap trapping Aedes albopictus. Methods Based on the factorial design, 6 CO 2 flow groups, 1 CO 2 blank control group, 10 monitoring periods and 7 sampling points were established. Mosquito lamps were placed at each sampling point and the mosquito traps were adjusted every 2 h CO_2 flow rate and replace the trap cage, the collected mosquitoes were classified and counted, the monitoring time was 02: 00-22: 00, to explore the flow of CO_2, monitoring period and sampling points of MT-1 CO_2 trap Aedes albopictus Effect of effect. Results (1) A total of 1122 mosquitoes were captured, of which 83.69% were Aedes albopictus. (2) The trapping effect of CO_2 on Aedes albopictus was higher than that of control (F = 3.05, P = 0.01) (3) The influence of different monitoring periods on the number of Aedes albopictus caught was statistically significant (F = 2.98, P = 0.03), 18: 00-20: 00 and 04 : 00-06: 00 There were more Aedes albopictus captured in both time periods; (4) Aedes albopictus captured at each sampling point had no significant difference (F = 0.47, P = 0.80). Conclusion The MT-1 CO 2 mosquito trapping device has the trapping effect on Aedes albopictus and can be used to monitor Aedes albopictus. It is recommended to hang the lamp in the evening and set the CO 2 flow to 6L / min.
