根据现场观察，2种密切相关的蚊子的集群行为。 A. 冈比亚 s.s.和 A. arabiensis 进行了描述和比较。从群体中捕获的雄性，通过电泳进行鉴定，使用冈比亚按蚊种群成员的生化密码。这些蜂群由雄性组成，栖息在乡村房屋之间、空旷的地方，可以看到天空。蜂群发生在黄昏，在大约 20 分钟的时间内，光强度从大约 55 勒克斯降至 1 勒克斯。记录下蜂群内或附近的交配情况。 2 个物种的群体之间没有发现空间和时间差异。并提供了在它们共存的地区出现混合集群的情况的证据。观察到的 A. gambiae s.s. 同域种群之间的遗传隔离。阿拉伯拟南芥的集群行为不能完全解释，其他尚未确定的因素也一定发挥了作用。
Based on field observations, the swarming behavior of 2 closely related mosquito species. A. gambiae s.s. and A. arabiensis, is described and compared. Males, captured from swarms, are identified by electrophoresis, using a biochemical key for the members of the A. gambiae group of species. The swarms are composed of males and are found between the houses of rural villages at sites with open ground and a free view of the sky. Swarming takes place at dusk, in a period of about 20 min during which the light intensity decreases from about 55 to 1 lux. Matings in, or near, the swarms are recorded. Neither spacial nor temporal differences are found between swarms of the 2 spp. and evidence is given for a case of mixed swarming in an area where they coexist. The observed genetical isolation between sympatric populations of A. gambiae s.s. and A. arabiensis can not be fully explained by their swarming behavior and that other, as yet unidentified, factors must play a role.
