在冈比亚的Keneba，使用在开阔地上设置的飞行诱捕器和吸力诱捕器调查了蚊子的垂直分布。飞行陷阱被用来采样三个水平，地面至1.37米，1.45 - 2.82米，和2.90 - 4.27米。在两个系列的实验中，在0.68、2.13和3.51 m的三个水平上安装了吸力阱，在第三个系列中，在0.91、305、6.10和9.15 m的四个水平上安装了吸力阱。大多数物种，包括按蚊melas Theo。，A.鳞状西奥，斑胸伊蚊Aedes punctothoracis（Theo.），Decens组、C. tritaeniorhynchus Giles，Mansonia africana（Theo.）和M. uniformis（Theo.），最常见于近地面，渔获量随高度而递减。C.萨拉西乌斯·西奥。虽然最大的渔获量是在9·15米处取得的，但在各级都很常见。只有C.尼夫西奥。和C.威舍在更高的陷阱中更常见。尽管A. melas和C.三带喙龙的数量在无月期间被捕获，其他物种的数量不受月相的影响。一般来说，有无月光对垂直分布的影响不大。然而，C. thalassius和C.在月光下，黑腹果蝇对飞行陷阱的吸引力更大，这可能与视觉反应有关。一个有限的系列的四级，人类诱饵渔获量，与捕手驻扎在同一高度的吸力陷阱的第三个系列，产生的结果类似的吸力陷阱收集。
The vertical distribution of mosquitoes was investigated at Keneba in The Gambia, using flight traps and suction traps set up over open ground. Flight traps were used to sample three levels, ground to 1·37 m, 1·45–2·82 m, and 2·90–4·27 m. Suction traps were mounted in two series of experiments at three levels, 0·68, 2·13 and 3·51 m, and in a third series at four levels, 0·91, 305, 6·10 and 9·15 m. Most species, including Anopheles melas Theo., A. squamosus Theo., Aedes punctothoracis (Theo.), the Culex decens group, C. tritaeniorhynchus Giles, Mansonia africana (Theo.) and M. uniformis (Theo.), were most common near the ground, with catches declining progressively with height. C. thalassius Theo. was frequent at all levels, although the largest catches were taken at 9·15 m. Only C. neavei Theo. and C. weschei Edw. were more common in the higher traps. Although larger catches of A. melas and C. tritaeniorhynchus were taken during moonless periods, the numbers of other species were unaffected by lunar phase. In general, the presence or absence of moonlight had little effect on vertical distribution. However, C. thalassius and the C. decens group were shown to be more attracted to flight traps in moonlight, and it is concluded that visual responses were involved. A limited series of four-level, human-bait catches, with the catchers stationed at the same heights as the suction traps of the third series, produced results similar to those of the suction trap collections.
