Mosquito samples were collected from rural and urban communities in three selected major towns in Southwestern Nigeria to determine the impact of urbanization on the diversity and abundance of Anopheles species associated with malaria transmission in human habitations. A total of ten Anopheles species were identified in the rural communities, while eight Anopheles species were identified in the urban communities. Out of the ten Anopheles species identified, only four species, Anopheles gambiae (Giles), Anopheles funestus (Giles), Anopheles moucheti (Evans), and Anopheles nili (Theobald), were established to be vectors of malaria occurring in greater than 50% of the rural communities. Only A. gambiae occurred in all the urban communities, while the other three major vectors occurred in not more than 20% of the urban communities. Margalef's and Shannon-Wiener indices showed that diversity and species richness were higher in the rural compared to the urban. Comprehensive information on malaria vector abundance and diversity in rapidly changing communities is an important tool in planning and implementing successful vector control programs.
从尼日利亚西南部三个选定的主要城镇的农村和城市社区收集了蚊子样本,以确定城市化对与人类住区疟疾传播相关的疟蚊物种多样性和丰度的影响。在农村社区共鉴定出 10 种疟蚊,而在城市社区则鉴定出 8 种疟蚊。在所鉴定的 10 种疟蚊中,只有 4 种疟蚊,即冈比亚疟蚊(Giles)、致倦库蚊(Giles)、淡色库蚊(Evans)和尼氏疟蚊(Theobald),被确定为农村社区中 50%以上疟疾的传播媒介。只有冈比亚疟蚊存在于所有城市社区,而其他三种主要媒介蚊则存在于不超过 20%的城市社区。玛格丽夫和香农-威纳指数表明,农村地区的多样性和物种丰富度高于城市地区。关于快速变化社区中疟疾媒介丰度和多样性的综合信息是规划和实施成功的媒介控制计划的重要工具。
