An unprecedented malaria outbreak occurred in Ubon Ratchathani Province, northeastern Thailand, in 2014. The province showed the highest number of malaria cases of all Thai provinces. Five entomological surveys were conducted at 8 sentinel sites from September 2013 to September 2015 to address the role of different species in malaria transmission. Mosquito collections were conducted using human landing catches and cow bait. A total of 10,369 mosquitoes were collected and 2,240 were morphologically identified as potential malaria vectors, including ( = 78), ( = 18), ( = 4), s.l. ( = 819), ( = 612), ( = 676), ( = 42), ( = 7), and ( = 142). Real-time polymerase chain reaction was used to screen for the presence of spp. in salivary glands. The proportion of primary vectors of surveyed villages was very low (<1%), and no -infected specimens were detected among in the 2,240 mosquitoes tested. The absence of positive samples during malaria outbreaks suggests that malaria transmission most likely occurred outside the villages, particularly in the deep-forested hilly areas that provided suitable habitats for competent malaria vectors. These results emphasize the need to develop vector control related to village community activities to reduce malaria transmission along Thailand border areas.
2014年，泰国东北部乌汶府发生了一场前所未有的疟疾疫情。该府的疟疾病例数在泰国所有省份中位居榜首。2013年9月至2015年9月期间，在8个哨点开展了5次昆虫学调查，以探讨不同蚊种在疟疾传播中的作用。采用人饵诱捕法和牛饵诱捕法采集蚊虫。共采集到10369只蚊子，其中2240只在形态学上被鉴定为潜在的疟疾传播媒介，包括（=78）、（=18）、（=4）、复合种（=819）、（=612）、（=676）、（=42）、（=7）和（=142）。采用实时聚合酶链反应检测唾液腺中疟原虫的存在情况。被调查村庄的主要传播媒介比例非常低（<1%），在检测的2240只蚊子中未检测到感染疟原虫的标本。疟疾疫情期间未出现阳性疟原虫样本，这表明疟疾传播很可能发生在村庄之外，特别是在为适宜的疟疾传播媒介提供了合适栖息地的深山丘陵地区。这些结果强调了开展与村庄社区活动相关的病媒控制以减少泰国边境地区疟疾传播的必要性。
