Thirteen botanical product repellent compounds such as 2-undecanone, capric, lauric, coconut fatty acids (and their methyl ester derivatives), and catnip oil were formulated in either Coppertone or Aroma Land lotions and evaluated against laboratory-reared Aedes aegypti L. (Diptera: Culicidae) mosquitoes. These formulations contained 7-15 wt/wt of the botanical repellent as the major active ingredient either pure or as mixtures. USDA standard repellent test cages were used to determine the complete protection time (CPT) of the different formulated repellents. Two of the evaluated formulations, a 7% capric acid in Coppertone (CPT 2.7 ± 0.6 h) and 7% coconut fatty acids containing carrylic acid, capric acid, and lauric acid in Coppertone (CPT 2.3 ± 2.0 h), provided strong repellency against mosquitoes up to 3 h, which was equivalent to the (N,N-diethyl-m-toluamide) DEET control (CPT 2.7 ± 0.6 h). This work suggests future potential for these botanical product-based repellents as alternatives to commercial DEET-containing products.
13 种植物源驱避化合物，如 2-十一酮、辛酸、月桂酸、椰子脂肪酸（及其甲酯衍生物）和荆芥油，分别配制于 Coppertone 或 Aroma Land 乳液中，并针对实验室饲养的埃及伊蚊（双翅目：蚊科）进行了评估。这些配方含有 7-15wt/wt 的植物驱避活性成分，无论是纯的还是混合物。美国农业部标准驱避试验笼用于确定不同配方驱避剂的完全保护时间（CPT）。评估的两种配方中，7%辛酸在 Coppertone 中的驱避效果（CPT 2.7 ± 0.6 h）和 7%椰子脂肪酸中含有的月桂酸、辛酸和癸酸在 Coppertone 中的驱避效果（CPT 2.3 ± 2.0 h）对蚊子的驱避效果很强，可持续长达 3 小时，与（N，N-二乙基间甲苯甲酰胺）DEET 对照品（CPT 2.7 ± 0.6 h）相当。这项工作表明，这些基于植物源的驱避剂未来可能成为商业 DEET 产品的替代品。
