The ability of Aedes albopictus Skuse to transmit several pathogens to humans makes it a very important mosquito with public health significance. Ecofriendly products as alternatives to synthetic chemicals for the control of mosquito vectors are needed. Therefore, the larvicidal and repellent effects of two nontoxic chemicals, butyl anthranilate (BA) and ethyl anthranilate (EA), at different concentrations were compared in A. albopictus. The repellency persistence of BA and three commercial mosquito repellent products (Liushen repellent spray, DKB Korean, Raid repellent spray) against A. albopictus was compared. The results showed that 0.1% concentrations of BA and EA solutions were highly toxic to A. albopictus larvae, and the mortality rate was >90% after 4 h of treatment. We found that BA was more repellent than EA, and at 0.1% BA and 1% EA, and the repellency rates were 53.62% and 38.47%, respectively. Overall, 5% BA presented a significantly longer repellency time than the three commercial repellent products against female A. albopictus. These results indicate that BA has significant larvicidal and repellent effects and can be exploited further for the development of ecofriendly alternatives to existing toxic chemicals currently used for mosquito control.

两种邻氨基苯甲酸酯类对白纹伊蚊的毒性和驱避性（双翅目：Cu科）。

白纹伊蚊的传播能力将多种病原体传播给人类，这使其成为具有重要公共卫生意义的非常重要的蚊子。需要生态友好的产品来替代合成化学物，以控制蚊媒。因此，在白术曲霉中比较了两种无毒化学品邻氨基苯甲酸丁酯（BA）和邻氨基苯甲酸乙酯（EA）的杀幼虫和驱避作用。比较了BA和三种商业驱蚊产品（六神驱蚊剂，DKB韩国药，Raid驱蚊剂）的驱除持久性。结果表明，浓度为0.1％的BA和EA溶液对白纹曲霉幼虫具有高毒性，治疗4小时后死亡率> 90％。我们发现BA的排斥力比EA高，在BA为0.1％和EA为1％时，驱蚊率分别为53.62％和38.47％。总体而言，5％BA的驱避时间比三种商业驱蚊产品对雌性A. albopictus的驱避时间长得多。这些结果表明，BA具有显着的杀幼虫和驱蚊作用，可以进一步用于开发目前用于蚊子控制的现有有毒化学品的环保替代品。
