Four insect repellent products (RPs) (RP 1, Experimental Repellent Lotion [Bayrepel 12%]; RP 2, Experimental Repellent Cream [Bayrepel 5%]; RP 3, Off! Insect Repellent II Aerosol [deet 15%]; and RP 4, Off! Skintastic II Cream [deet 7.5%]) were evaluated simultaneously for their efficacy against vector and nuisance mosquitoes. The aim of this study was to compare the relative efficacy of RPs based on a new repellent compound, Bayrepel (1-piperidinecarboxylic acid, 2-(2-hydroxyethyl)-1-methylpropylester), with deet (N,N-diethyl-m-toluamide)-based RPs. An 8-h field efficacy of above repellents was evaluated against the day-biting mosquito (Aedes albopictus) and night-biting mosquitoes (Culex quinquefasciatus and Anopheles spp.). Evaluation was carried out by exposing humans with repellent-treated bare limbs to mosquitoes landing and to mosquitoes landing and biting. Repellent product 1 or 2 was applied on the left arm and leg, whereas RP 3 or 4 was applied on the right arm and leg, respectively. Application of these 4 RPs significantly reduced (P < 0.05) the landing and the landing and biting of day-biting and night-biting mosquitoes. All 4 RPs were found to be equally effective (P < 0.05) against Ae. albopictus and Cx. quinquefasciatus. However, for protection against Anopheles spp., RPs 1 and 3 exhibited significantly (P < 0.05) better repellency effect than RPs 2 and 4.
同时评估了四种驱虫产品（RPs）（RP 1，实验驱虫乳液[避蚊胺12%]；RP 2，实验驱虫乳膏[避蚊胺5%]；RP 3，Off！驱虫气雾剂II[避蚊胺15%]；以及RP 4，Off！Skintastic II乳膏[避蚊胺7.5%]）对病媒蚊子和骚扰性蚊子的防治效果。本研究的目的是比较基于新型驱虫化合物Bayrepel（1-哌啶羧酸，2-(2-羟乙基)-1-甲基丙酯）的驱虫产品与基于避蚊胺（N,N-二乙基间甲苯酰胺）的驱虫产品的相对防治效果。评估了上述驱虫产品对白天叮咬的蚊子（白纹伊蚊）和夜间叮咬的蚊子（致倦库蚊和按蚊属）的8小时野外防治效果。通过将涂抹了驱虫剂的裸露四肢暴露于蚊子着陆以及蚊子着陆并叮咬的情况来进行评估。驱虫产品1或2分别涂抹在左臂和左腿上，而RP 3或4分别涂抹在右臂和右腿上。涂抹这4种驱虫产品显著降低了（P<0.05）白天叮咬和夜间叮咬蚊子的着陆以及着陆并叮咬的情况。发现所有4种驱虫产品对白纹伊蚊和致倦库蚊的防治效果相同（P<0.05）。然而，对于预防按蚊属，RP 1和RP 3的驱避效果显著（P<0.05）优于RP 2和RP 4。
