Tests were conducted to determine the persistence of compounds applied to tents to protect against mosquitoes. Interiors of 2 camping tents were treated by the manufacturer--one with the repellent dimethyl phthalate (DMP) and one with the insecticide permethrin. A third tent was untreated. Tents were set up outdoors and exposed to weathering for one year. Weekly tests were conducted by releasing Aedes aegypti into the tents, then recording knockdown (KD) and biting behavior during a 3-h period. Weather data were collected 24 h/day during the study. Year-long mean KD of mosquitoes exposed in the tent to permethrin was 58.6%, to DMP 2.7% and the control 0.9%. Mean biting was 11.9, 43.8 and 58%, respectively. Under constant exposure to weathering, the permethrin-treated tent gave best results with average protection from bites greater than 96% for 9 months (DMP was less than 31%). Although preliminary, the data suggest permethrin would be effective as a tent treatment to reduce annoyance of mosquitoes.
进行了多项试验以确定涂抹在帐篷上用于防蚊的化合物的持久性。两家露营帐篷制造商对帐篷内部进行了处理，一家使用驱蚊剂邻苯二甲酸二甲酯（DMP），另一家使用杀虫剂氯菊酯。第三顶帐篷未作处理。帐篷搭建在户外，经受一年的风化作用。每周进行测试，将埃及伊蚊放入帐篷，然后记录3小时内的击倒率（KD）和叮咬行为。研究期间每天24小时收集天气数据。在帐篷中接触氯菊酯的蚊子全年平均击倒率为58.6%，接触DMP的为2.7%，对照组为0.9%。平均叮咬率分别为11.9%、43.8%和58%。在持续经受风化作用的情况下，经氯菊酯处理的帐篷效果最佳，9个月内平均防叮咬率大于96%（DMP处理的帐篷防叮咬率小于31%）。尽管这些数据尚属初步，但表明氯菊酯作为一种帐篷处理剂可有效减少蚊虫滋扰。
