A study was undertaken in the villages of Korea and Bastar district (Chhattisgarh) during the years 2012-2015 to investigate the bionomics of malaria vectors and the prevalence of their sibling species complexes. Entomological surveys carried out every month included indoor resting collections, pyrethrum spray catches, light trap catches, and insecticide susceptibility status of using World Health Organization (WHO) methods. and species were assayed by polymerase chain reaction (PCR) for the detection of malaria parasite, and sibling species were identified using PCR and DNA sequencing. A total of 13,186 samples of Anopheles comprising 15 species from Bastar and 16 from Korea were collected. was recorded as the most dominant species and also the only active vector at both sites. This species was found to be resistant to dichlorodiphenyltrichloroethane (DDT) and Malathion, showing signs of emerging resistance against pyrethroids. Among the sibling species of , the group BCE was found in maximum numbers, while sibling species T of the was recorded to be dominant among its complex. The study provides a comprehensive view of the vector bionomics in the highly malarious regions of India that may have importance in developing vector control strategies.
2012年至2015年期间，在韩国和巴斯塔尔地区（恰蒂斯加尔邦）的村庄开展了一项研究，以调查疟疾病媒的生物学特性及其同胞物种复合体的流行情况。每月进行的昆虫学调查包括室内栖息采集、除虫菊酯喷雾捕获、诱虫灯捕获，以及使用世界卫生组织（WHO）方法检测杀虫剂敏感性状况。通过聚合酶链反应（PCR）检测 和 物种的疟原虫，并使用PCR和DNA测序鉴定同胞物种。共采集了13186份按蚊样本，其中来自巴斯塔尔的有15种，来自韩国的有16种。 被记录为最主要的物种，也是两个地点唯一的活跃病媒。发现该物种对滴滴涕（DDT）和马拉硫磷具有抗性，显示出对拟除虫菊酯类杀虫剂出现抗性的迹象。在 的同胞物种中，BCE组数量最多，而 的同胞物种T在其复合体中占主导地位。该研究全面展示了印度疟疾高发地区病媒的生物学特性，这可能对制定病媒控制策略具有重要意义。
