在萨赫勒地区的一个村庄,随着时间的推移,蚊子的空间分布的变化进行了研究,以了解蚊子的来源在旱季时,没有幼虫situations.In那个时候,冈比亚按蚊Giles的来源可能是当地的夏眠蚊子或从遥远的人口移民使用的庇护所。蚊子的分布在旱季更加集中,很少有房屋的密度比预期高出7至24倍。旱季的高密度房屋与雨季的不同。大多数高密度的房屋在旱季期间每年都有变化,但它们的附近相当稳定。扫描统计数据证实,在旱季有一两个相邻的热点,通常在村庄的一边。这些热点在旱季的早期和晚期之间转移。在雨季,热点是相对稳定的主要幼虫的网站附近。在雨季和旱季早期和晚期的热点的位置是相似的。季节性的,稳定的,焦点热点是不一致的预测的基础上从遥远的地方在旱季移民的到来,但与预测的基础上使用的夏眠蚊子的地方庇护所是一致的。针对萨赫勒村庄的热点进行病媒控制可能不会有效,因为聚集程度适中,热点不容易预测,而且它们不是人口的来源。然而,一旦能够确定和预测旱季住所,以旱季住所为目标可能具有很高的成本效益。
Changes in spatial distribution of mosquitoes over time in a Sahelian village were studied to understand the sources of the mosquitoes during the dry season when no larval sites are found. At that time, the sources of Anopheles gambiae Giles may be local shelters used by aestivating mosquitoes or migrants from distant populations. The mosquito distribution was more aggregated during the dry season, when few houses had densities 7- to 24-fold higher than expected. The high-density houses during the dry season differed from those of the wet season. Most high-density houses during the dry season changed between years, yet their vicinity was rather stable. Scan statistics confirmed the presence of one or two adjacent hotspots in the dry season, usually found on one edge of the village. These hotspots shifted between the early and late dry season. During the wet season, the hotspots were relatively stable near the main larval site. The locations of the hotspots in the wet season and early and late dry season were similar between years. Season-specific, stable, and focal hotspots are inconsistent with the predictions based on the arrival of migrants from distant localities during the dry season, but are consistent with the predictions based on local shelters used by aestivating mosquitoes. Targeting hotspots in Sahelian villages for vector control may not be effective because the degree of aggregation is moderate, the hotspots are not easily predicted, and they are not the sources of the population. However, targeting the dry-season shelters may be highly cost-effective, once they can be identified and predicted.
