季节性数量和以人为食的趋势是衡量疟疾病媒有效控制的重要参数。本研究的目的是描述在伊朗南部的四个疟疾媒介的摄食模式，丰度和休息行为之间的关系。这项研究是在位于伊朗南部和东南部的山区/丘陵和平原地区的10个指标村庄（根据疟疾发病率和昆虫学指数）进行的。从室内和室外收容所收集蚊媒，并通过ELISA试验检测血餐。在所有7654只雌性按蚊属中。捕获的按蚊中，最常见的是斯氏按蚊（Anophelesstephensi）、斯氏按蚊（An. culicifacies、隐翅虫属（An.）fluviatilis和安.达里人血总指数分别为37.50%、19.83%、16.4%和30.1%。fluviatilis，安. stephensi，安氏隐翅虫An. culicifacies和An. d 'thali，分别。此外，安。河栖按蚊全年都以人血为食，但其取食行为与人血无关。stephensi和安氏隐翅虫An.库相随季节变化而变化。总体而言，每个人类收容所的雌蚊对人血呈阳性的丰度为4.25%，而每个动物收容所为17.5%。这一结果表明，媒介生物在取食人类后有在动物庇护所休息的倾向。因此，病媒生物控制措施应根据该地区这些病媒生物的取食模式、丰度和休息行为来规划。
Seasonal abundance and tendency to feed on humans are important parameters to measure for effective control of malaria vectors. The objective of this study was to describe relation between feeding pattern, abundance, and resting behavior of four malaria vectors in southern Iran. This study was conducted in ten indicator villages (based on malaria incidence and entomological indices) in mountainous/hilly and plain regions situated south and southeastern Iran. Mosquito vectors were collected from indoor as well as outdoor shelters and the blood meals were examined by ELISA test. Over all 7654 female Anopheles spp. were captured, the most common species were Anopheles stephensi, An. culicifacies, An. fluviatilis, and An. d'thali. The overall human blood index was 37.50%, 19.83%, 16.4%, and 30.1% for An. fluviatilis, An. stephensi, An. culicifacies, and An. d'thali, respectively. In addition, An. fluviatilis fed on human blood during the entire year but the feeding behavior of An. stephensi and An. culicifacies varied according to seasons. Overall, the abundance of the female mosquito positive to human blood was 4.25% per human shelter versus 17.5% per animal shelter. This result indicates that the vectors had tendency to rest in animal shelters after feeding on human. Therefore, vector control measure should be planned based on such as feeding pattern, abundance, and resting behavior of these vectors in the area.
