对按蚊及其与疟疾传播的关系进行了3次研究：1999年7月和8月; 1999年12月; 2000年8月和9月。这些研究在老挝人民民主共和国东南部甘蒙省疟疾流行的村庄进行。共收集到28种使用人类和动物诱饵。人饵引诱大劣按蚊和安氏按蚊的优势种。微小疟原虫，通过解剖、PCR和酶联免疫吸附测定法检测恶性疟原虫和间日疟原虫的子孢子，将其鉴定为载体。的向量容量。dirus为0.009-0.428，而An.最小值为0.048 ~ 0.186。接种率为100%。dirus为0.052-0.137（Boualapha; 2000年8月）。一个. nivipes及其姊妹种An. Philippinensis主要是嗜动物性的，尽管在稻田地区的那些村庄中也有相当数量的雌性被人类诱饵所吸引。一个.用动物诱饵采集的标本中检测到菲律宾吸虫感染间日疟原虫卵囊。这两个物种被认为是Khammouane省的病媒。四种，一个. notanandai，An. sawadwongporni，安. willmori和An. hodgkini，以前在老挝没有记录。提供的信息主机的偏好和夜间叮咬活动的常见物种和疟疾的发病率在研究领域。
Anopheline mosquitos and their relation to malaria transmission were studied 3 times: in July and August, 1999; in December, 1999; and in August and September, 2000. The studies took place in the malaria endemic villages of Khammouane Province, southeast of Lao PDR. A total of 28 species were collected using human and animal bait. Human bait attracted predominantly Anopheles dirus and An. minimus, which were identified as vectors by the detection of sporozoites by dissection, PCR, and enzyme-linked immunosorbent assays for Plasmodium falciparum and P. vivax. The vectorial capacity of An. dirus was 0.009-0.428, while that of An. minimus was 0.048-0.186. The inoculation rate of An. dirus was 0.052-0.137 (Boualapha; August, 2000). An. nivipes and its sister species, An. philippinensis, were principally zoophilic, although a considerable number of the females were also attracted to human bait in the villages of the paddy field areas. An. philippinensis infected with oocysts of P. vivax was detected in a specimen collected by animal bait. These two species were considered as vectors in Khammouane Province. Four species, An. notanandai, An. sawadwongporni, An. willmori, and An. hodgkini, had not been recored before in Lao PDR. Information is provided on host preference and the nocturnal biting activities of common species and the incidence of malaria in the study areas.
