目的确定在家庭层面使用长效杀虫蚊帐（LLINS）是否能有效减少印度、尼泊尔和孟加拉国人传人内脏利什曼病的媒介银足白蛉的丰度。方法在比哈尔邦（印度）三个地方病村庄的选定房屋中评估了两种长效蚊帐（Olyset和PermaNet）对室内白蛉丰度的影响。据推测，大多数白蛉在室内繁殖，并认为在繁殖季节，LLIN将逐步减少室内密度。一个运动的室内喷洒二氯二苯基三氯乙烷（DDT）干扰试验，但并没有影响白蛉population.RESULTS只有男性的P. argentipes的密度显着降低了两个LLINs，但不是females.CONCLUSIONS这些发现表明，大多数女性白蛉是来自外部和LLINs不降低其进入率。
OBJECTIVE To determine whether the use of long-lasting insecticidal nets (LLINS) at household level are effective in reducing the abundance of Phlebotomus argentipes, vector of anthroponotic visceral leishmaniasis in India, Nepal and Bangladesh.METHODS The impact of two long-lasting nets (Olyset and PermaNet) on indoor sandfly abundance was evaluated in selected houses of three endemic hamlets in Bihar (India). It was assumed that most sandflies breed inside the houses and that LLINs would progressively reduce the indoor density during the reproduction season. A campaign of indoor spraying with dichloro-diphenyl-trichloroethane (DDT) interfered with the trial but did not affect the sandfly population.RESULTS Only the density of males of P. argentipes was significantly reduced by both the LLINs but not the females.CONCLUSIONS These findings suggest that most female sandflies are coming from outside and that LLINs do not reduce their entry rate.
