The long-lasting insecticidal nets (LLINs) have been promulgated to compensate the low re-impregnation rate of conventional mosquito nets. Today, the cornerstone of the fight against malaria vectors is based on a large distribution of these LLINs for universal coverage. Despite this promotion, the question of their effective life in operational conditions remains unresolved. Between September and October 2013, a survey was conducted in 11 districts of Senegal where LLINs were sampled and routed to the laboratory for assessing their physical integrity and biological effectiveness. A total of 207 LLINs that were sampled in the 11 districts have been monitored during this study. Our results showed that Olyset® Net and PermaNet® 2.0 are the most represented brands in the districts. These two major brands have a good biological efficiency providing a high rate of knockdown despite their failing physical integrity.
长效驱虫蚊帐（LLINs）已被推广，以弥补传统蚊帐再浸渍率低的问题。如今，抗击疟疾媒介的基石在于广泛分发这些长效驱虫蚊帐以实现普遍覆盖。尽管有这种推广，但它们在实际使用条件下的有效使用寿命问题仍未得到解决。2013年9月至10月期间，在塞内加尔的11个地区进行了一项调查，对长效驱虫蚊帐进行采样并送往实验室，以评估其物理完整性和生物有效性。在这项研究中，共监测了在11个地区采样的207顶长效驱虫蚊帐。我们的结果表明，奥力赛网（Olyset® Net）和PermaNet® 2.0是这些地区中最具代表性的品牌。这两个主要品牌具有良好的生物效率，尽管其物理完整性有所下降，但仍能提供较高的击倒率。
