The succession of mosquito species and their abundance was observed through one cycle of dry-season irrigated rice cultivation near Bansang in The Gambia. The study covered a 21-week period, February-June 1975. Mosquitoes were sampled using a single suction trap located in a dry field beside the rice fields. Few mosquitoes were present before irrigation began. Anopheles gambiae s.1., A. rufipes and Culex neavei reached peak numbers 4 weeks after full-scale irrigation began and then declined in abundance. These three species were amongst the four (with Culex poicilipes) most abundant mosquitoes taken by the suction trap, comprising 85.4% of the total captures. Anopheles pharoensis, Culex ethiopicus and C. poicilipes were most common around the middle of the rice-growing cycle 6-13 weeks after the start of full irrigation and showed more extended peaks of abundance. Anopheles ziemanni alone reached maximum numbers as the rice crop neared maturity. C. antennatus, Mansonia africana and M. uniformis were present throughout the period of observations, but their numbers showed little relation with the cycle of the rice growth.
在冈比亚班桑附近，通过旱季灌溉水稻种植的一个周期，观察了蚊子种类的演替及其数量。该研究涵盖了1975年2月至6月的21周时间。使用位于稻田旁一块旱地中的单个吸气式诱捕器对蚊子进行采样。在灌溉开始前几乎没有蚊子。冈比亚按蚊复合体、红足按蚊和内氏库蚊在全面灌溉开始4周后数量达到峰值，随后数量下降。这三个物种是吸气式诱捕器捕获的四种（与波氏库蚊一起）数量最多的蚊子之一，占总捕获量的85.4%。法氏按蚊、埃塞俄比亚库蚊和波氏库蚊在全面灌溉开始后6 - 13周的水稻生长周期中期最为常见，且数量峰值持续时间更长。仅齐氏按蚊在水稻作物接近成熟时数量达到最大值。触角库蚊、非洲曼蚊和纯色曼蚊在整个观察期内都有出现，但它们的数量与水稻生长周期关系不大。
