在摩洛哥，利什曼病病媒控制的主要策略是基于环境改造。通常设想使用合成拟除虫菊酯进行局部滞留室内喷洒。评估这种控制方法的必要性是必要的。目前的研究旨在确定 IRS 项目对摩洛哥北部利什曼病流行区利什曼病媒介的有效性。这项调查是在摩洛哥北部三个不同地区的四个邻近地点进行的：塞夫鲁区的 Ait Chaib 和 Aichoun、Bouassem（布尔马内）和 Lmrouj（陶纳特）。 2010年、2011年和2012年，Ait Chaib和Lmrouj地区采用了高效氯氰菊酯室内滞留喷雾，剂量为30 mg/m2，同时Aichoun和Bouassem地区作为对照。在 2011 年和 2012 年的 4 月至 11 月期间，使用粘性诱捕器每两个月在这四个研究区域收集白蛉，以确定其丰度和摄食模式。使用 WHO 锥体生物测定测试评估了高效氯氰菊酯 IRS 的残留效应。通过每个研究区域的被动和主动病例检测来估计利什曼病发病率。比较已喷洒农药和未喷洒农药的地区，发现利什曼病发病率和妊娠率显着降低。所用浓度的高效氯氰菊酯的残留活性在喷洒后可持续 10 周。然而，白蛉的丰度并未受到高效氯氰菊酯 IRS 的显着影响。这项研究表明，IRS 对利什曼病传播有显着影响；因此，可以推荐将其作为利什曼病高传播地区控制利什曼病的有效工具。
In Morocco, the main strategies of leishmaniasis vector control are based on environmental modifications. Use of local residual indoor spraying with synthetic pyrethroids is often envisaged. The need to evaluate this control method is essential. The current study was conducted to determine the efficacy of an alphacypermethrin IRS program against leishmaniasis vectors in an endemic area in the north of Morocco. The survey was conducted in four neighbouring localities in three different districts in northern Morocco: Ait Chaib and Aichoun in Sefrou district, Bouassem (Boulmane) and Lmrouj (Taounate). Indoor residual spraying with alphacypermethrin at a dose of 30 mg/m2 was used in Ait Chaib and Lmrouj localities during 2010, 2011 and 2012, while localities of Aichoun and Bouassem were taken as control. In the four studied areas, sand flies were collected bimonthly from April to November in 2011 and 2012, using sticky traps, to determine their abundance and feeding pattern. Alphacypermethrin IRS were evaluated for their residual effect using the WHO cone bioassay test. Leishmaniasis incidence was estimated by passive and active case detection in each study area. Significant reductions in leishmaniasis incidence and in gravidity rate were observed when comparing sprayed and unsprayed localities. The residual activity of alphacypermethrin at the concentration used lasted 10 weeks after spraying. However, the abundance of sand flies was not significantly affected by alphacypermethrin IRS. This study indicated that IRS has a significant impact on leishmaniasis transmission; therefore it could be recommended as an effective tool for leishmaniasis control in areas with high leishmaniasis transmission.
