Abstract

A systematic survey on Anopheline species abundance, bionomics and habitat preference was conducted for three years in Thenzawl, Mizoram. A scoop?net method was employed for larval collection and a local made killing-jar for adults.? A total of 10 species Anopheles campestris (25.8%), An. nivipes (24.0%), An. vagus (20.6%), An. jamesii (15.1%), An. jeyporiensis (11.4%), An. maculatus (1.7%), An. philippinensis (0.7%), An. annularis (0.26%), An. sinensis (0.23%) and An. peditaeniatus (0.22%) were collected. The survey site having thick tall grasses, numerous rural-huts as residents, small? to relatively larger ponds and very slow running water bodies well shaded from sunlight with floating aquatic plants provided the largest area for Anopheles larvae breeding and accounted for 40% of all Anopheles larva and 25.4% total Anopheles spp. collected. An. campestris (NSK01), maculatus (NSK04), philippinensis (NSK06), nivipes (NSK10) and jeyporiensis (NSK09) were strongly anthropogenic and endophagic while vagus (NSK18) and jamesii (NSK03) were found to be highly zoophilic and exophilic and An. peditaeniatus (NSK02), annularis (NSK07) and sinensis (NSK15) were found to be highly zoophilic. Because of its abundance and bionomics, An. campestris, jeyporiensis and nivipes may have played a role in malarial transmission throughout the year. This is the first study reported on Anopheline distribution and abundance in Thenzawl, Mizoram.
