In malaria endemic forested villages in Orissa State, India, a 3-year comparison of nylon nets treated with lambdacyhalothrin at 25 mg/m2, untreated nets, and no nets was carried out. Treated nets retained high insecticidal efficacy for more than 7 months. Nets washed after 3 months of use gave 98% kill in a bioassay with a 3-min exposure. Based on these bioassays during the first year, nets were later reimpregnated at 6-monthly intervals with participation of the users. Compliance with the use of nets was good. Eighty-eight percent of nets were usable even after 3 years. The main benefits perceived by treated net users were reductions in malaria, mosquito bites, head louse infestations, and other nuisance insects. The trial was well accepted by the community. Issues related to social marketing and promotion of nets are discussed.
在印度奥里萨邦疟疾流行的森林村庄，对用25毫克/平方米高效氯氟氰菊酯处理过的尼龙蚊帐、未处理的蚊帐和无蚊帐情况进行了为期3年的比较。处理过的蚊帐在7个多月内保持了较高的杀虫效果。使用3个月后清洗的蚊帐在3分钟接触的生物测定中杀死率为98%。根据第一年的这些生物测定结果，后来在用户参与下每隔6个月对蚊帐重新进行浸渍处理。蚊帐的使用依从性良好。即使在3年后，88%的蚊帐仍可使用。使用处理过的蚊帐的用户感受到的主要益处是疟疾、蚊虫叮咬、头虱感染和其他害虫减少。该试验得到了社区的广泛认可。文中还讨论了与蚊帐社会营销和推广相关的问题。
