2000年1月至2001年12月，在泰国西部坎恰纳布里Tri-Yok县Ball Pu Teuy对按蚊幼虫和成虫进行了采样。在为期2年的时间内，按蚊微小广义宽是最常见的收集物种，其次是按蚊swadiwongporni和按蚊大劣广义宽，所有这三个物种是重要的媒介疟疾在泰国。安试图吸血。极小值出现在整个夜间，有两个明显的摄食高峰：日落后立即出现强烈活动（18时至21时），然后在日出前出现第二次不太明显的上升（3时至6时）。微小按蚊更丰富，在潮湿的季节相比，干燥和炎热的季节，虽然夜间成人喂养模式相似。微小按蚊在室内和室外都很容易取食人类，表现出轻微的外食偏好。咬人的安峰。在我们的研究区域的微小的不同，从其他地方在泰国采样，表明可能存在的特定地点的人口。表现出不同的寄主寻找行为。这些结果突出表明，必须进行针对具体地点的研究，以准确确定病媒幼虫的生境和成虫的活动模式，并将它们在特定地区疟疾传播中的重要性联系起来。
Anopheline mosquito larvae and adults were sampled at Ball Pu Teuy, Tri-Yok District, Kanchanaburi Province, western Thailand, from January 2000 to December 2001. Over the period of 2 yr, Anopheles minimus sensu lato was the most commonly collected species, followed by Anopheles swadiwongporni and Anopheles dirus sensu lato; all three species are important vectors of malaria in Thailand. Attempted blood feeding by An. minimus occurred throughout the night, with two distinct feeding peaks: strong activity immediately after sunset (1800-2100 hours), followed by a second, less pronounced, rise before sunrise (0300-0600 hours). Anopheles minimus were more abundant during the wet season compared with the dry and hot seasons, although nocturnal adult feeding patterns were similar. Anopheles minimus fed readily on humans inside and outside of houses, showing a slight preference for exophagy. The human-biting peak of An. minimus in our study area differed from other localities sampled in Thailand, indicating the possible existence of site-specific populations of An. minimus exhibiting different host-seeking behavior. These results underscore the importance of conducting site-specific studies to accurately determine vector larval habitats and adult activity patterns and linking their importance in malaria transmission in a given area.
