A cytogenetic analysis of the species status of members of the Anopheles dirus group, from natural populations, over a six-year period has produced biogeographic and behavioural data which are presented herein. Species A, B, C and D have quite distinct geographic distributions in Thailand. Species A is the only species in most of the mainland but is absent from the southern half of the peninsula. Species B is dominant in the far south of the peninsula giving way to species C on the north-east side and rarely occurring on the west side of the peninsula; it is unknown from the northern half or the rest of the country. Species C is known from the middle eastern side of the peninsula and from a site far to the north along the Burmese border. Species D occurs down the mountains along the Burmese/Thai border and along the north half of the western peninsula. Each species appears to have distinct times of biting during the night. They also appear to have differential seasonal abundance. These data together with the differing geographic distributions suggest some implications for Plasmodium transmission and that care should be taken to identify these genetic species during malariometric studies.
在六年时间里，对来自自然种群的大劣按蚊组成员的物种状况进行了细胞遗传学分析，得出了生物地理学和行为学数据，本文予以呈现。物种A、B、C和D在泰国有着相当不同的地理分布。物种A是大陆大部分地区唯一的物种，但半岛南半部没有。物种B在半岛最南端占主导地位，在半岛东北侧被物种C取代，在半岛西侧很少出现；在该国北半部或其他地区未发现。物种C在半岛中东侧以及沿缅甸边境向北很远的一个地点被发现。物种D分布在沿缅甸/泰国边境的山脉以及半岛西半部北半部沿线。每个物种似乎在夜间有不同的叮咬时间。它们似乎也有不同的季节丰度。这些数据连同不同的地理分布对疟原虫传播有一些启示，并且在疟疾调查研究期间应注意识别这些遗传物种。
