Mosquitoes were surveyed (Oct. 2010 & Apr. - Oct. 2011) in some localities representing 13 centers of El-Dakahlia Governorate. Six mosquito species were collected: Culex pipiens, Cx. antennatus, Cx. perexiguus, Ochlerotatus detritus, Anopheles pharoensis and An. tenebrosus. Culex pipiens was predominating (ca 79% larvae, 51% adults). Culex antennatus and Cx. perexiguus were also common. Of the Four types of the breeding habitats, the drainage canals were the most productive (53.4% larvae). For the three common species, the compiled larval density increases as water temp. increased and decreases as pH increased while adult indoor density increases as indoor and outdoor temp. and indoor RH increased and decreases as outdoor RH increased. Cx. pipiens significantly associated with Cx. antennatus (CAB=0.88 & I=0.48) while Cx. antennatus has a moderate association with Cx. perexiguus (CAB=0.47 & I=0.36). Out of 908 examined blood samples from ten centers, 7.49% were infected with Wuchereria bancrofti. The highest infection rates in some centers were associated with high indoor densities of Cx. pipiens females, the main filariasis vector. The situation necessitates a wide vector control program to minimize lymphatic filariasis transmission in this Governorate.
2010年10月以及2011年4月至10月期间，在代盖赫利耶省13个中心的一些地点对蚊子进行了调查。共采集到六种蚊子：尖音库蚊、触角库蚊、伪杂鳞库蚊、骚扰伊蚊、法老按蚊和阴暗按蚊。尖音库蚊占主导地位（幼虫约占79%，成虫约占51%）。触角库蚊和伪杂鳞库蚊也很常见。在四种繁殖栖息地类型中，排水渠的繁殖力最强（幼虫占53.4%）。对于三种常见蚊子，汇总的幼虫密度随水温升高而增加，随pH值升高而降低，而成虫室内密度随室内外温度以及室内相对湿度升高而增加，随室外相对湿度升高而降低。尖音库蚊与触角库蚊显著相关（卡方关联度=0.88，I=0.48），而触角库蚊与伪杂鳞库蚊有中度关联（卡方关联度=0.47，I=0.36）。在来自十个中心的908份检测血样中，7.49%感染了班氏吴策线虫。一些中心的最高感染率与主要丝虫病传播媒介尖音库蚊雌蚊的高室内密度有关。这种情况需要实施广泛的病媒控制计划，以尽量减少该省淋巴丝虫病的传播。
