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.
