Effectiveness of Personal Protection against Mosquitoes in Alaska

摘要

A personal protection system consisting of an extended-duration repellent formulation containing 35% N,N-diethyl-m-toluamide (deet) and a permethrin-treated battle dress uniform (0.125 mg permethrin AI/sq. cm) was tested against Culiseta impatiens (Walker) at Galena, Alaska. Participants wearing the system received 1 mosquito bite per h (99.9% protection), whereas those with an untreated uniform and no repellent received 1,188 mosquito bites per h. Deet alone provided greater than 99% protection (4 mosquito bites per h) for more than 8 h, whereas the permethrin-treated uniform alone provided 93% protection (78 mosquito bites per h).
