Aedes aegypti (L.) and Aedes albopictus (Skuse) were surveyed using ovitraps in residential areas in Chiang Mai, northern Thailand. Egg populations (both species inclusive) remained low in the dry season, but increased/decreased exponentially during the first/latter half of the rainy season, respectively. This seasonal pattern was similar to the seasonal distribution of dengue haemorrhagic fever cases in the area. During the dry season (November-March) Ae.aegypti was dominant in urban and indoor ovitraps. With onset of the rainy season in April, relative abundance of Ae.albopictus increased in rural and outdoor ovitraps. Ae.albopictus displaced Ae.aegypti in the latter half of the rainy season in the rural area. Possible mechanisms to account for this seasonal decline of Ae.aegypti and reciprocal fluctuations in relative abundance of Ae.albopictus are discussed in relation to food availability for larvae in container habitats.
在泰国北部清迈的居民区，使用诱蚊产卵器对埃及伊蚊（L.）和白纹伊蚊（Skuse）进行了调查。在旱季，包括两种蚊子在内的蚊卵数量保持在较低水平，但在雨季的前半段/后半段分别呈指数增长/下降。这种季节性模式与该地区登革出血热病例的季节性分布相似。在旱季（11月至3月），埃及伊蚊在城市和室内诱蚊产卵器中占主导地位。随着4月雨季的到来，白纹伊蚊在农村和室外诱蚊产卵器中的相对丰度增加。在农村地区，白纹伊蚊在雨季后半段取代了埃及伊蚊。结合容器栖息地中幼虫的食物供应情况，讨论了导致埃及伊蚊季节性减少以及白纹伊蚊相对丰度相互波动的可能机制。
