biting midges were collected using UV light traps from nine livestock farms in Kanchanaburi Province, Thailand. Collections were made one night per month from June 2020 to May 2021 to determine the seasonal changes and spatial distribution of the assemblage. The influence of four environmental factors (temperature, rainfall, humidity, and wind speed), types of animals in each shed (cattle, pigs, and avians), and neighboring animals (those in the other sheds and their proximity) were assessed. A subsample of 130,670 out of a total of 224,153 specimens collected was identified and counted. The collections were predominantly female (76.9%), though males were also commonly collected (23.1%). The dominant species included (97,098 individuals; 43.0%), (55,579; 24.6%), (45,996; 20.4%), and (15,703; 7.0%), while other species accounted for the remaining 9777 individuals (4.4%). Trap captures were strongly influenced by seasons and animal sheds. Cattle exhibited the greatest effect on the community, likely due to their large biomass. Humidity and temperature had a positive effect on trap captures, whereas wind speed exhibited a negative effect. Cattle positively influenced all major species, except for , which showed a positive association with avians. A "neighboring effect" was also observed. Additionally, the lowest dispersal ability of was suggested.
在泰国北碧府的9个畜牧场，使用紫外线诱捕器收集蠓虫。于2020年6月至2021年5月期间，每月进行一晚的采集，以确定该类群的季节变化和空间分布。评估了四个环境因素（温度、降雨量、湿度和风速）、每个畜棚中的动物类型（牛、猪和禽类）以及相邻动物（其他畜棚中的动物及其距离）的影响。在总共收集的224,153个标本中，对130,670个样本进行了鉴定和计数。收集到的主要是雌性（76.9%），不过雄性也很常见（23.1%）。优势物种包括（97,098只个体；43.0%）、（55,579只；24.6%）、（45,996只；20.4%）和（15,703只；7.0%），而其他物种占其余9777只个体（4.4%）。诱捕器捕获情况受季节和动物畜棚的强烈影响。牛对群落的影响最大，可能是由于其生物量较大。湿度和温度对诱捕器捕获有积极影响，而风速则呈现负面影响。牛对所有主要物种都有积极影响，但与禽类呈正相关。还观察到了“邻域效应”。此外，表明的扩散能力最低。
