Flies are implicated in carrying and mechanically transmitting many primate pathogens. We investigated how fly associations vary across six monkey species (Cercopithecus ascanius, Cercopithecus mitis, Colobus guereza, Lophocebus albigena, Papio anubis, and Piliocolobus tephrosceles) and whether monkey group size impacts fly densities. Fly densities were generally higher inside groups than outside them, and considering data from these primate species together revealed that larger groups harbored more flies. Within species, this pattern was strongest for colobine monkeys, and we speculate this might be due to their smaller home ranges, suggesting that movement patterns may influence fly-primate associations. Fly associations increase with group sizes and may thus represent a cost to sociality.
苍蝇被认为在携带和机械传播许多灵长类病原体方面发挥了作用。我们调查了苍蝇在六种猴子物种（Cercopithecus ascanius、Cercopithecus mitis、Colobus guereza、Lophocebus albigena、Papio anubis 和 Piliocolobus tephrosceles）中的分布情况有何不同，以及猴子群体大小是否会影响苍蝇密度。苍蝇密度通常在群体内部比外部更高，并且综合这些灵长类物种的数据表明，更大的群体栖息着更多的苍蝇。在物种内，这种模式在疣猴科动物中最强，我们推测这可能是由于它们的活动范围较小，表明运动模式可能会影响苍蝇与灵长类动物的联系。苍蝇的联系随着群体规模的增加而增加，因此可能代表着社交的代价。
