摘要: 目的 研究不同浓度乙醇溶解新型驱蚊剂原液后的不同配比溶液对白纹伊蚊的有效驱避时间,以便筛选出适合制备驱避剂的乙醇浓度和新型驱蚊剂的配比浓度。方法 分别用75%和35%乙醇溶液将新型驱蚊剂原液稀释成不同梯度浓度:溶剂为75%乙醇溶液时,配制成15%、10%、8%的新型驱蚊剂溶液;溶剂为35%乙醇溶液时,配制成浓度为8%的新型驱蚊剂溶液。参照国家标准《农药登记用卫生杀虫剂室内药效试验及评价驱避剂》(GB/T 13917.9-2009)执行。结果 新型驱蚊剂有效浓度为8%时,75%乙醇溶液作为溶剂时有效保护时间为4.63 h,而35%乙醇溶液作为溶剂时有效保护时间为3.74 h。75%乙醇溶液作为溶剂时,白纹伊蚊的驱避效果随新型驱蚊剂制剂的有效浓度提高而延长,新型驱蚊剂浓度为8%、10%、15%的有效保护时间分别为4.63、5.42和6.10 h。结论 75%乙醇溶液适合作为新型驱蚊剂原液的溶剂,且有效浓度为15%时对白纹伊蚊的驱避效果良好。

Abstract: Objective To investigate the effective protection time against Aedes albopictus of different concentrations of new mosquito repellent solution dissolved by different concentrations of ethanol, and to determine a suitable ethanol concentration for repellent formulation with an appropriate repellent concentration. Methods According to "Laboratory efficacy test methods and criterions of public health insecticides for pesticide registration-Part 9:Repellent" (GB/T 13917.9-2009), the stock solution of the new mosquito repellent was diluted to gradient concentrations separately with 75% ethanol (15%, 10%, and 8% repellent solutions) and 35% ethanol (8% repellent solution). Results The effective protection time of 8% repellent was 4.63 h when it was prepared with 75% ethanol, and 3.74 h with 35% ethanol. With 75% ethanol as the solvent, the effective protection time was prolonged with the increase of the effective concentration of the new mosquito repellent formulation, being 4.63 h, 5.42 h, and 6.10 h for 8% repellent, 10% repellent, and 15% repellent, respectively. Conclusion Seventy-five percent ethanol is a suitable solvent for the stock solution of the new mosquito repellent, and the repellent effect against Ae. albopictus is good at an effective concentration of 15%.
