A study comparing the effectiveness of barrier treatment of military tents with bifenthrin and permethrin in preventing entry of mosquitoes was conducted at Wide Bay Training Area, Queensland, Australia. Five military tents were erected at a site in bushland at Mosquito Creek, about 2 km from the coast. Two tents were sprayed with bifenthrin (Bistar 80SC, 0.1% mix, 12.5 ml/liter) and 2 with permethrin (Perigen 500, 1.2%, 24 ml/liter). One was left untreated and served as a control. Carbon dioxide-baited traps were placed inside each tent 0, 2, 4, 6, and 8 wk after treatment, and a single trap was placed in forest 50 m from the tents. The predominant mosquito species collected was Aedes vigilax (78% of collection). Compared to the untreated control, protection against mosquitoes entering treated tents was initially 78.6% for bifenthrin-treated tents and 84.3% for permethrin. At 4 wk, protection was 68.6% for bifenthrin and 50.7% for permethrin. After 6 wk, less than 34% protection was provided by either insecticide. There was no significant difference between the protection provided by either insecticide treatment. The study showed that barrier tent treatments provide a reasonable increase in preventing the entry of mosquitoes for at least 4 wk.
在澳大利亚昆士兰州的宽湾训练区，开展了一项比较使用联苯菊酯和氯菊酯对军用帐篷进行屏障处理以防止蚊子进入的效果的研究。在距离海岸约2公里的蚊子溪灌木丛中的一处地点搭建了5顶军用帐篷。2顶帐篷喷洒了联苯菊酯（Bistar 80SC，0.1%混合液，12.5毫升/升），2顶喷洒了氯菊酯（Perigen 500，1.2%，24毫升/升）。1顶未作处理作为对照。处理后0、2、4、6和8周，在每顶帐篷内放置二氧化碳诱蚊灯，并且在距离帐篷50米的森林中放置1个诱蚊灯。采集到的主要蚊种是刺扰伊蚊（占采集总数的78%）。与未处理的对照相比，最初，经联苯菊酯处理的帐篷对进入帐篷的蚊子的防护率为78.6%，经氯菊酯处理的帐篷为84.3%。在4周时，联苯菊酯的防护率为68.6%，氯菊酯为50.7%。6周后，两种杀虫剂提供的防护率均低于34%。两种杀虫剂处理提供的防护之间没有显著差异。该研究表明，对帐篷进行屏障处理在至少4周内可合理增加防止蚊子进入的能力。
