Five hundred and fifty-nine female biting midges were collected, and seventeen species in six subgenera (, and ) and two groups ( and ) were identified. The dominant species was (30.94%), followed by subgenus . From blood meal analysis of engorged biting midges, they were found to feed on cows, dogs, pigs, and avians. The majority of blood preferences of biting midges (68%; 49/72) displayed a mixed pattern of host blood DNA (cow and avian). The overall non-engorged biting midge field infectivity rate was 1.44 % (7/487). We detected sp. in three specimens, one from each species: , , and subgenus . sp. was found in two specimens, and sp. and were separately found in two . More consideration should be paid to the capacity of biting midges to transmit pathogens such as avian haemosporidian and trypanosomatid parasites. To demonstrate that these biting midges are natural vectors of trypanosomatid parasites, additional research must be conducted with a greater number of biting midges in other endemic regions.
共采集了559只雌性蠓，鉴定出6个亚属（、和）和2个类群（和）中的17个物种。优势种为（30.94%），其次是亚属。通过对饱血蠓的血餐分析发现，它们以牛、狗、猪和鸟类为食。大多数蠓的血液偏好（68%；49/72）表现为宿主血液DNA（牛和鸟类）的混合模式。未饱血蠓的总体野外感染率为1.44%（7/487）。我们在3个标本中检测到了种，每个物种各1个：、和亚属。在2个标本中发现了种，在2个标本中分别发现了种和。应更多关注蠓传播禽血孢子虫和锥虫寄生虫等病原体的能力。为证明这些蠓是锥虫寄生虫的自然传播媒介，必须在其他流行地区对更多蠓进行进一步研究。
