To investigate the prevalence of container breeding mosquitoes with emphasis on the seasonality and larval habitats of Aedes aegypti (Ae. aegypti) in Makkah City, adjoining an environmental monitoring and dengue incidence.
Monthly visits were performed between April 2008 and March 2009 to randomly selected houses. During each visit, mosquito larvae were collected from indoors and outdoors containers by either dipping or pipetting. Mosquitoes were morphologically identified. Data on temperature, relative humidity, rain/precipitations during the survey period was retrieved from governmental sources and analyzed.
The city was warmer in dry season (DS) than wet season (WS). No rain occurred at all during DS and even precipitations did fall, wetting events were much greater during WS. Larval survey revealed the co-breeding of Aedes, Culex and Anopheles in a variety of artificial containers in and around homes. 32 109 larvae representing 1st , 2nd, 3rd, and 4th stages were collected from 22 618 container habitats. Culicines was far the commonest and Aedes genus was as numerous as the Culex population. Ae. aegypti larval abundance exhibited marked temporal variations, overall, being usually more abundant during WS. Ten types of artificial containers were found with developing larvae. 70% of these habitats were located indoors. 71.42% of indoor containers were permanent and 28.58% was semi-permanent during WS. Cement tanks was the only container type permanent during DS. Ae. aegypti larval indices (CI, HI, BI) recorded were greater during WS.
Taken together, these results indicate a high risk of dengue transmission in the holy city.
以麦加市埃及伊蚊的季节性和幼虫栖息地为重点，调查容器滋生蚊子的情况，并进行环境监测和登革热发病率调查。
在2008年4月至2009年3月期间，每月对随机选择的房屋进行走访。每次走访时，通过 dipping 或 pipetting 方法从室内和室外容器中收集蚊子幼虫。对蚊子进行形态学鉴定。从政府来源获取并分析调查期间的温度、相对湿度、降雨/降水量数据。
该市旱季比雨季温暖。旱季完全没有降雨，即使在雨季有降雨，湿润事件在雨季也更多。幼虫调查显示，伊蚊、库蚊和按蚊在家庭内外的各种人工容器中共同滋生。从22618个容器栖息地收集了代表第1、2、3和4阶段的32109只幼虫。库蚊科最为常见，伊蚊属的数量与库蚊种群一样多。埃及伊蚊幼虫的丰度表现出明显的时间变化，总体而言，在雨季通常更为丰富。发现有10种人工容器中有发育中的幼虫。其中70%的栖息地位于室内。在雨季，71.42%的室内容器是永久性的，28.58%是半永久性的。水泥池是旱季唯一的永久性容器类型。在雨季记录的埃及伊蚊幼虫指数（容器指数、房屋指数、布雷图指数）更高。
综上所述，这些结果表明圣城存在登革热传播的高风险。
