蚊种埃及伊蚊Aedes Aegypti(L.)已知是传播各种疾病的媒介，包括登革热和黄热病。使用驱蚊剂是预防措施之一，用于通过减少蚊子叮咬来降低人类感染这些疾病的风险。奈培拉内酯是一种有效的天然驱蚊剂，主要存在于猫草精油中，已成为一种有希望的驱蚊剂。在这里，我们评估了猫草精油(>； 95%奈派拉内酯)作为驱蚊剂的潜力。采用Y型管嗅觉仪，以人手为引诱剂，分析了猫草油驱除埃及伊蚊的效果。我们测试了一系列稀释的猫草精油，发现低至2%的浓度在驱避剂喷洒后1至4小时内对70%的 >； 蚊子有有效的驱蚊效果。这些发现表明，奈派拉内酯可能被用作合成驱蚊剂的天然、有效替代品，从而提供对媒介传播疾病的保护。
The mosquito species Aedes aegypti (L.) is known to act as a vector in the transmission of various diseases, including dengue fever and yellow fever. The use of insect repellents is one of precautionary measures used to mitigate the risk of these diseases in humans by reducing mosquito biting. Nepetalactone, a potent natural insect repellent primarily found in catnip (Nepeta cataria) essential oil, has emerged as a promising candidate for mosquito repellence. Here, we evaluated the potential of catnip essential oil (> 95% nepetalactone) for use as a mosquito repellent. Using a Y-tube olfactometer and human hands as an attractant, we analysed the effectiveness of catnip oil at repelling the mosquito species Aedes aegypti. We tested a range of dilutions of catnip essential oil and found that concentrations as low as 2% were effective at repelling > 70% of mosquitoes for between one and four hours after repellent application. These findings suggest that nepetalactone could potentially be used as a natural, effective alternative to synthetic mosquito repellents, thereby offering protection against vector-borne diseases.
