Title
Biology of culex sitiens, a predominant mosquito in PhangNga, Thailand after a tsunami
Abstract
A tsunami affected area in Phang Nga province, Thailand was explored randomly as some
freshwater sites had changed into brackish-water sites. A survey of four areas found Culex sitiens
to be the most dominant mosquito species.This mosquito prefers to breed in putrefied water with
garbage and it was found in almost every stagnant, brackish-water site in full sunlight. The larval
density was more than 300 larvae/dip/250 ml water. Its biting cycle, determined by human
landing catch, was nocturnal, with a single peak at 19.00-20.00 hr. The maximum rate was 108
mosquitoes per person/hour. The biology of the mosquito was studied by colonization in natural
water under laboratory conditions. The mean number of eggs per raft was 158.1 ± 31.7,
hatchability 96.6 ± 4.1%, development from 1st instar larvae to adult was 8.8-11.7 days, and
longevity of adult males was 7.3-41.3 days and females 11.0-52.7 days. The ratio of adult males
to adult females was 1:1.1 ± 0.2.
