Anopheline fauna of cattlesheds (CS) in Ajodhya hills, District Purulia, consisted of 12 species during summer, monsoon and 10 species during winter. Of the six vector species encountered in CS, Anopheles culicifacies, An. annularis, An. subpictus, An. maculatus and An. fluviatilis were found in all the three seasons. An. philippinensis was encountered in monsoon only and constituted 0.61% of the total anopheline catch made during the season. An. culicifacies was the most predominant species during summer (MHD 30.38) and monsoon (MHD 11) but ranked third (MHD 9.64) to An. annularis (MHD 16.28) during winter; An. subpictus being second (MHD 10.28) in order of predominance. An. annularis was the second most prevalent vector species in summer (MHD 21.38) and monsoon (MHD 9.92). The population density of the remaining three vector species was extremely low in the two seasons. In human dwelling (HD), of the five anopheline species encountered (An. subpictus, An. annularis, An. culicifacies, An. vagus and An. splendidus), the former three were found in all the three seasons. MHD of An. annularis in HD in summer, monsoon and winter was 3.7, 1.1 and 1.9 respectively, while MHD of An. culicifacies in the corresponding seasons was 5.01, 2.09 and 1.31 respectively.
普鲁利亚县阿约迪亚山牛棚的按蚊种类，夏季和季风季节有12种，冬季有10种。在牛棚中发现的6种媒介按蚊中，嗜人按蚊、环纹按蚊、伪杂鳞库蚊、多斑按蚊和溪流按蚊在三个季节均有发现。菲律宾按蚊仅在季风季节出现，占该季节按蚊捕获总数的0.61%。嗜人按蚊在夏季（平均叮人率30.38）和季风季节（平均叮人率11）是最主要的种类，但在冬季仅次于环纹按蚊（平均叮人率16.28），排名第三（平均叮人率9.64）；伪杂鳞库蚊在优势顺序中排第二（平均叮人率10.28）。环纹按蚊是夏季（平均叮人率21.38）和季风季节（平均叮人率9.92）第二常见的媒介种类。其余三种媒介按蚊在这两个季节的种群密度极低。在人类住所中，发现的5种按蚊（伪杂鳞库蚊、环纹按蚊、嗜人按蚊、迷走按蚊和华丽按蚊）中，前三种在三个季节均有发现。环纹按蚊在人类住所夏季、季风季节和冬季的平均叮人率分别为3.7、1.1和1.9，而嗜人按蚊在相应季节的平均叮人率分别为5.01、2.09和1.31。
