Abstract:

Objective To evaluate the efficacy of ultra?low?volume (ULV) spraying and residual spraying, and the combined application of the two, in control of mosquitoes. Methods We used ULV spraying and residual spraying, alone or combined, to control mosquitoes. Mosquito density was monitored using animal?baited net traps, light traps, and labor hour method before and after application of the controlling methods. Results Residual spraying reduced indoor mosquito density, but had no significant effect on outdoor mosquito density. ULV spraying reduced indoor mosquito density too. However, mosquito density monitoring using light traps showed increased density after ULV spraying, while monitoring using animal?baited net traps showed decreased density. Conclusion Combined use of residual spraying and ULV spraying can improve mosquito control efficacy. Mosquito density monitoring using goat?baited net trap is a reliable method in evaluating the mosquito control effect of ULV spraying.

摘要:

目的 探讨超低容量喷雾和滞留喷洒在杀灭蚊虫中搭配使用的效果。方法 应用车载超低容量喷雾、烟雾机进行超低容量喷雾, 普通喷雾器进行滞留喷洒, 不同灭蚊方式单独或综合运用, 在喷药前后对蚊虫密度采用动物帐诱法、诱蚊灯法和人工小时法进行监测, 确定不同喷药方法的灭蚊效果。结果 滞留喷洒可降低室内蚊虫密度, 但对室外蚊虫活动无明显影响;超低容量喷雾也可降低室内蚊虫密度, 但室外诱蚊灯法监测的蚊虫密度通常会增高, 动物帐诱法监测的蚊密度会降低。结论 同时使用滞留喷洒和超低容量喷雾, 可以提高蚊虫控制效果;羊帐诱法是评价超低容量喷雾现场灭蚊效果较好的方法。
