孟加拉国有关疟疾病媒的资料非常有限。在不断变化的环境中，不同种类的按蚊可能会在传播循环中起作用。这项研究的目的是确定按蚊物种和可能的疟疾病媒在边境地带，那里的疟疾是孟加拉国的地方病。在疟疾传播高峰期（5月至8月），从三个边境地带（Lengura，Deorgachh和Matiranga）收集按蚊。采用了三种不同的方法：人类着陆捕获，口吸器和CDC灯诱捕器的休息收集。采用酶联免疫吸附试验（ELISA）检测采集的雌虫体内的恶性疟原虫、间日疟原虫210和间日疟原虫247环子孢子蛋白（CSP）。共采集按蚊雌蚊17种634只。优势种为迷走按蚊（18.6%），其次为黑按蚊（14.5%）和菲律宾按蚊（11.0%）。用CSP-ELISA法检测622只蚊虫，感染率为2.6%。属于5个物种的8只（1.3%）蚊子对恶性疟原虫呈阳性，属于5个物种的7只（1.1%）蚊子对间日疟原虫-210呈阳性，1只（0.2%）被鉴定为斑按蚊的蚊子对间日疟原虫-247呈阳性。卡氏按蚊的感染率最高（22.2%），其次为卡氏按蚊（22.2%）。斑蚊占14.3%，短吻按蚊占9.5%。其它阳性种为安氏按蚊。黑热病（4.4%）、安.迷走按蚊（4.3%）、近点按蚊（1.5%）和按蚊（1.5%）。philippinensis（1.4%）。迷走按蚊和按蚊。菲律宾人以前在孟加拉国被认为是疟疾病媒。相比之下，安。卡尔瓦里角隐翅虫An. maculatus、斑斑隐翅虫An. barbirostris、尖吻隐翅虫An. nigerrimus和安.孟加拉国以前从未将假证罪定为犯罪。这项研究的结果表明，在缺乏主要疟疾病媒的情况下，其他按蚊物种可能在孟加拉国的疟疾传播中发挥了作用。因此，需要对本研究中发现的阳性蚊子物种进行进一步研究，以调查它们在孟加拉国疟疾传播中的可能作用。
Information related to malaria vectors is very limited in Bangladesh. In the changing environment and various Anopheles species may be incriminated and play role in the transmission cycle. This study was designed with an intention to identify anopheline species and possible malaria vectors in the border belt areas, where the malaria is endemic in Bangladesh. Anopheles mosquitoes were collected from three border belt areas (Lengura, Deorgachh and Matiranga) during the peak malaria transmission season (May to August). Three different methods were used: human landing catches, resting collecting by mouth aspirator and CDC light traps. Enzyme-linked immunosorbent assay (ELISA) was done to detect Plasmodium falciparum, Plasmodium vivax-210 and Plasmodium vivax-247 circumsporozoite proteins (CSP) from the collected female species. A total of 634 female Anopheles mosquitoes belonging to 17 species were collected. Anopheles vagus (was the dominant species (18.6%) followed by Anopheles nigerrimus (14.5%) and Anopheles philippinensis (11.0%). Infection rate was found 2.6% within 622 mosquitoes tested with CSP-ELISA. Eight (1.3%) mosquitoes belonging to five species were positive for P. falciparum, seven (1.1%) mosquitoes belonging to five species were positive for P. vivax -210 and a single mosquito (0.2%) identified as Anopheles maculatus was positive for P. vivax-247. No mixed infection was found. Highest infection rate was found in Anopheles karwari (22.2%) followed by An. maculatus (14.3%) and Anopheles barbirostris (9.5%). Other positive species were An. nigerrimus (4.4%), An. vagus (4.3%), Anopheles subpictus (1.5%) and An. philippinensis (1.4%). Anopheles vagus and An. philippinensis were previously incriminated as malaria vector in Bangladesh. In contrast, An. karwari, An. maculatus, An. barbirostris, An. nigerrimus and An. subpictus had never previously been incriminated in Bangladesh. Findings of this study suggested that in absence of major malaria vectors there is a possibility that other Anopheles species may have been playing role in malaria transmission in Bangladesh. Therefore, further studies are required with the positive mosquito species found in this study to investigate their possible role in malaria transmission in Bangladesh.
