频繁监测蚊媒的丰度、分布和季节性对确定疾病传播风险具有重要意义。近年来，马来西亚槟城岛的登革热感染病例有所增加，疫情反复发生。然而，由于缺乏有关病媒的最新信息，正在进行的控制努力受到严重阻碍。为了克服这一问题，我们审查了岛上登革热病媒的现状和分布。在2009年2月至2010年2月的旱季和雨季期间，对城市、郊区和农村地区的住宅进行了检查。调查中发现了两种病媒，埃及伊蚊的数量特别多，主要在城市地区。类似的观察也注意到Ae。农村白纹伊蚊。前者在室外容器中丰度更高，后者在室外和室内的丰度几乎相当。登革热病毒在城市和农村地区都很活跃，在伊蚊孳生的地区感染病例较多。埃及伊蚊占优势。大量的未成熟Ae。白纹伊蚊与降雨量呈显著正相关（r2 = 0.461, P < 0.05），而伊蚊与降雨量无显著正相关。蚊。两种未成熟种群的大小均随降雨强度的增加而增加，但暴雨导致种群数量减少。除了更新有关幼虫栖息地和地点（室外和室内）的数据外，本研究还强调了空间媒介控制分层的重要性，这有可能降低控制计划的成本。
Abstract It is important to obtain frequent measurements of the abundance, distribution, and seasonality of mosquito vectors to determine the risk of disease transmission. The number of cases of dengue infection has increased in recent years on Penang Island, Malaysia, with recurring epidemics. However, ongoing control attempts are being critically hampered by the lack of up-to-date information regarding the vectors. To overcome this problem, we examined the current situation and distribution of dengue vectors on the island. Residences throughout the urban, suburban, and rural areas were inspected through wet and dry seasons between February 2009 and February 2010. Two vectors were encountered in the survey, with Aedes aegypti present in especially high numbers mostly in urban areas. Similar observations were noted for Ae. albopictus in rural areas. The former species was more abundant in outdoor containers, while the latter showed almost equivalent abundance both outdoors and indoors. The dengue virus was active in both urban and rural areas, and the number of cases of infection was higher in areas where Ae. aegypti was predominant. The abundance of immature Ae. albopictus was positively correlated with rainfall (r2 = 0.461; P < 0.05), but this was not the case for Ae. aegypti. For both species, the size of immature populations tended to increase with increasing intensity of rain, but heavy rains resulted in population loss. In addition to updating data regarding the larval habitats and locations (outdoors and indoors), this study highlighted the importance of spatial vector control stratification, which has the potential to reduce costs in control programs.
