Organic insect repellents are of interest to many agricultural producers and animal owners. Geraniol, a plant-derived alcohol, is naturally produced by a wide range of plants and is a US Environmental Protection Agency minimum risk pesticide. Previous studies have shown various concentrations of geraniol repel or kill mosquitoes; however, geraniol might cause allergic contact dermatitis in humans or animals. We tested a commercially available 2% aqueous solution of geraniol on ponies as a mosquito repellent. Five trials were conducted on ponies treated with a 60-ml aerosol mist (30 ml per side) of 2% geraniol or as untreated controls. Animals were observed 3 h postapplication to check for skin irritation. Aedes aegypti, in feeding tubes, were held on the ponies for 7 min. The average percent of biting on control animals was 56%, with a range of 16-90%, and the average for the treatments was 13%, with a range of 0-86%. Based on statistical models, there was no significant difference (P = 0.081) in the percent bites between treated and untreated animals after 3 h. Based on our data, 2% geraniol was not an adequate mosquito repellent for horses. We did not observe any skin irritation on the animals treated with 2% geraniol.
有机驱虫剂受到许多农业生产者和动物饲养者的关注。香叶醇是一种植物衍生的醇类，由多种植物自然产生，是美国环境保护局认定的最低风险农药。先前的研究表明，不同浓度的香叶醇能驱赶或杀死蚊子；然而，香叶醇可能会导致人类或动物发生过敏性接触性皮炎。我们在小马身上测试了一种市售的2%香叶醇水溶液作为驱蚊剂的效果。对用60毫升（每侧30毫升）2%香叶醇气雾剂喷雾处理的小马进行了五次试验，并设置了未处理的对照组。在用药后3小时观察动物是否有皮肤刺激。将置于喂食管中的埃及伊蚊放在小马身上7分钟。对照动物被咬的平均百分比为56%，范围在16%至90%之间，处理组的平均百分比为13%，范围在0%至86%之间。根据统计模型，3小时后处理组和未处理组动物被咬百分比没有显著差异（P = 0.081）。根据我们的数据，2%香叶醇对马匹来说不是一种有效的驱蚊剂。我们没有观察到用2%香叶醇处理的动物有任何皮肤刺激现象。
