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.
泰国攀牙府的一个海啸灾区被随机勘探，因为一些淡水地点已经变成了咸水地点。对四个地区的调查发现，库蚊是最主要的蚊子物种。这种蚊子喜欢在有垃圾的腐臭水中繁殖，几乎在每个阳光充足的静止、咸水地点都能找到。幼虫密度超过 300 条/滴/250 毫升水。根据人体降落捕获法确定，其叮咬周期为夜间，19:00-20:00 时出现单峰。最大率为每小时 108 只蚊子。通过在实验室条件下的自然水中进行殖民化研究了蚊子的生物学特性。每个筏子上的平均产卵数为 158.1±31.7 个，孵化率为 96.6±4.1%，从 1 龄幼虫发育到成虫需要 8.8-11.7 天，雄性成虫的寿命为 7.3-41.3 天，雌性成虫的寿命为 11.0-52.7 天。雌雄成虫的比例为 1:1.1±0.2。
