Synanthropy and community structure of Ceratopogonidae in temperate Argentina were compared across an urbanization gradient to assess the impact of urbanization on species diversity and abundance. Adult ceratopogonids were collected from one natural, one Peri-urban, and two urban sites monthly for 12 months using CDC light traps. Nine-hundred one individuals belonging to nine genera and 59 species were collected. Forcipomyia Meigen was the genus with the highest species richness (n = 20), followed by Atrichopogon Kieffer (14), Dasyhelea Kieffer (8), Stilobezzia Kieffer (7), Culicoides Latreille (5), Bezzia Kieffer (2), Alluaudomyia Kieffer, Monohelea Kieffer, and Palpomyia Meigen (1). Only 15 species were present at the three different areas. Indices of species abundance (ISA) values were statistically similar between urban and Peri-urban areas, but these were significantly lower than those from the natural area. Atrichopogon balseiroi Spinelli, Dasyhelea sp. C., Forcipomyia poulaineae Ingram, and Macfie and F. nana (Macfie) were positively associated with rain fall, while A. albinensis, A. delpontei, D. suarezi, Forcipomyia sp. B, F. sp. I, F. pinamarensis, and F. calchaqui were associated to relative humidity. Species diversity was reduced in urbanized areas and these areas favored ubiquitous species: Forcipomyia taragui Marino, Spinelli and Cazorla, F. poulaineae, and Culicoides venezuelensis Ortiz and Mirsa.
在温带阿根廷，对趋同现象和库蠓科的群落结构进行了比较，以评估城市化对物种多样性和丰度的影响。使用 CDC 诱捕器每月从一个自然、一个城郊和两个城市地点收集一次成虫库蠓，共 12 个月。共收集到 901 只个体，属于 9 个属和 59 个种。Forcipomyia Meigen 是物种丰富度最高的属（n = 20），其次是 Atrichopogon Kieffer（14）、Dasyhelea Kieffer（8）、Stilobezzia Kieffer（7）、Culicoides Latreille（5）、Bezzia Kieffer（2）、Alluaudomyia Kieffer、Monohelea Kieffer 和 Palpomyia Meigen（1）。只有 15 个种存在于这三个不同的区域。物种丰度指数（ISA）值在城市和城郊地区之间统计学上相似，但明显低于自然地区。Atrichopogon balseiroi Spinelli、Dasyhelea sp. C.、Forcipomyia poulaineae Ingram 和 Macfie 和 F. nana（Macfie）与降雨量呈正相关，而 A. albinensis、A. delpontei、D. suarezi、Forcipomyia sp. B、F. sp. I、F. pinamarensis 和 F. calchaqui 与相对湿度有关。物种多样性在城市化地区减少，这些地区有利于普遍存在的物种：Forcipomyia taragui Marino、Spinelli 和 Cazorla、F. poulaineae 和 Culicoides venezuelensis Ortiz 和 Mirsa。
