Tabanidae (horse flies and deer flies) are hematophagous insects that cause direct and indirect damage to animal production. The aims of this study were to determine the preferred site, time of day, and duration of tabanid feeding on beef cattle and identify factors related to infestation by tabanids. The population of tabanids was surveyed on certain body parts of the beef cattle (fore udder, tail, navel, leg, dewlap, body, and under) during the morning hours (9.00-10.30 a.m.), midday (12.00-13.30 a.m.), and afternoon (15.30-17.00 p.m.) every day for 10 days. The findings showed that two genera, Linnaeus, 1758, and Meigen, 1803, landed on the cows. The leg was statistically significantly the most frequent landing site for tabanids (15.067 ± 7.54) compared with other parts. The average feeding duration for each insect was 2.76 ± 1.77 min. The results showed that a significant number of tabanids were present during midday, as compared with the morning and afternoon. Temperature was found to be positively associated with fly abundance. A regression model was derived in this study (y = 4.23x - 116.09). This information is important for tabanid control and prevention in beef cattle.
虻科（马蝇和鹿蝇）是吸血昆虫，会对动物生产造成直接和间接损害。本研究的目的是确定虻在肉牛身上的偏好叮咬部位、每日叮咬时间及持续时间，并识别与虻侵袭相关的因素。在10天的时间里，每天上午（9:00 - 10:30）、中午（12:00 - 13:30）和下午（15:30 - 17:00）对肉牛的某些身体部位（前乳房、尾巴、肚脐、腿部、颈部垂皮、身体及身体下部）的虻数量进行调查。结果显示，有1758年林奈命名的两个属以及1803年梅根命名的属的虻落在牛身上。与其他部位相比，腿部在统计学上是虻最常落的部位（15.067 ± 7.54）。每只昆虫的平均叮咬持续时间为2.76 ± 1.77分钟。结果表明，与上午和下午相比，中午出现的虻数量显著更多。发现温度与虻的数量呈正相关。本研究得出了一个回归模型（y = 4.23x - 116.09）。这些信息对于肉牛虻的控制和预防很重要。
