Boric acid (1%) in 5% sugar water bait solution was applied as a spray to the foliage, stems, and other surfaces of plants for control of adult Aedes albopictus, Culex nigripalpus, and Ochlerotatus taeniorhynchus. Initial studies outdoors in small (1.42-m3) screened cages showed that exposure of male and female mosquitoes to 1% boric acid bait for 48 h resulted in 80 to 100% mortality in Ae. albopictus and > or = 98% mortality in Cx. nigripalpus and Oc. taeniorhynchus. At 48 h posttreatment, in large (1,178-m3) outdoor screened cages, 1% boric acid bait applied as a spray to plant surfaces significantly reduced the landing rates of Ae. albopictus and Cx. nigripalpus on a human subject as well as the numbers of these two species captured in mechanical traps, compared with responses for adults exposed to 5% sugar water solution only (control). Boric acid bait treatments in large screened cages did not significantly reduce landing rates or trap captures of Oc. taeniorhynchus. The application of boric acid baits to plant surfaces may be an effective adulticidal method for selected species of pest and disease vector mosquitoes.
将含1%硼酸的5%糖水诱饵溶液作为喷雾剂喷洒在植物的叶子、茎和其他表面上,以控制白纹伊蚊、黑须库蚊和海滨伊蚊成虫。最初在室外小型(1.42立方米)网笼中的研究表明,雄性和雌性蚊子暴露于1%硼酸诱饵48小时后,白纹伊蚊的死亡率为80%至100%,黑须库蚊和海滨伊蚊的死亡率≥98%。处理后48小时,在大型(1178立方米)室外网笼中,将1%硼酸诱饵作为喷雾剂喷洒在植物表面,与仅暴露于5%糖水的对照组相比,显著降低了白纹伊蚊和黑须库蚊在人体上的着陆率以及这两个物种在机械诱捕器中的捕获数量。大型网笼中的硼酸诱饵处理并未显著降低海滨伊蚊的着陆率或诱捕捕获量。在植物表面施用硼酸诱饵可能是一种针对特定种类的害虫和疾病传播媒介蚊子的有效成虫防治方法。
