The trophic behavior and host preference of two sibling species, Anopheles minimus s.s. (= An. minimus species A) and species C, were observed during a two-year period at Pu Teuy Village, Sai Yok District, Kanchanaburi Province, western Thailand. Anopheles minimus s.s. and species C were more prevalent during the hot and wet periods of the year. Both species demonstrated exophagic and zoophilic activities. Feeding activity of An. minimus C was unique compared to An. minimus sensu lato from other localities in Thailand. Outdoor blood feeding by An. minimus C occurred throughout the night with one distinct feeding peak immediately after sunset (1800 h), whereas indoor feeding showed two small peaks at 2000 and 2400 h. The small number of An. minimus s.s collected during this study precluded a determination of peak activity patterns. A better understanding of mosquito behavior related to host and patterns of feeding activity will facilitate and improve the efficiency of vector control operations.
在泰国西部北碧府赛育区普特伊村，对微小按蚊指名亚种（=微小按蚊A种）和C种这两个近缘种的摄食行为和宿主偏好进行了为期两年的观察。微小按蚊指名亚种和C种在一年中的炎热潮湿时期更为常见。这两个物种都表现出嗜外性和嗜动物性活动。与泰国其他地区广义微小按蚊相比，微小按蚊C种的摄食活动具有独特性。微小按蚊C种在户外整夜都有吸血行为，日落后（18:00）立即出现一个明显的吸血高峰，而室内吸血在20:00和24:00出现两个小高峰。在本研究中收集到的微小按蚊指名亚种数量较少，无法确定其活动高峰模式。更好地了解与宿主相关的蚊子行为和摄食活动模式将有助于并提高病媒控制行动的效率。
