The vertical distribution of blood-feeding flies in two temperate forests in the southeastern U.S.A. was determined by placing 15 Centers for Disease Control and Prevention miniature light traps (12 CO(2)-baited, three unbaited controls), without lights, at three heights (1.5 m, 5.0 m, 10.0 m). More than 6550 haematophagous flies, representing 49 species in four families, were collected. Eighteen species were taken almost exclusively (90-100%) at 1.5 m or 10.0 m, and the mean number of flies per trap differed significantly with height for another six species. Five species exhibited shifts in vertical distribution between the two forests, indicating that forest structure could influence the height of host searching. Most (52.5%) mammalophilic flies were collected at 1.5 m, whereas most (56.4%) ornithophilic flies were taken at 10.0 m, suggesting that host associations influence vertical distributions. The significant differences in the composition of haematophagous fly populations among forest strata emphasize the importance of trap placement in vector surveillance and of understanding the ecological relationships of blood-feeding flies.
通过在美国东南部两个温带森林中的三个高度（1.5米、5.0米、10.0米）放置15个疾病控制与预防中心微型诱捕器（12个用二氧化碳诱饵，3个无诱饵对照）且不开灯，确定了吸血蝇的垂直分布。共收集到6550多只吸血蝇，分属四个科49个物种。18个物种几乎完全（90 - 100%）在1.5米或10.0米高度捕获，另外6个物种每个诱捕器捕获的蝇平均数量随高度有显著差异。有5个物种在两个森林之间垂直分布发生了变化，表明森林结构可能影响宿主搜寻高度。大多数（52.5%）嗜哺乳动物蝇在1.5米高度捕获，而大多数（56.4%）嗜鸟蝇在10.0米高度捕获，这表明宿主关联影响垂直分布。森林不同层次吸血蝇种群组成的显著差异强调了诱捕器放置在病媒监测中的重要性以及理解吸血蝇生态关系的重要性。
