In the tropics, the botfly Dermatobia hominis and the NWS Cochliomyia hominivorax are the most important myiasis agents in cattle. It is frequently reported that furuncular lesions due to D. hominis are a predisposing cause for screwworm myiasis. Our results pointed out that only 5.2 to 7.4% of C. hominivorax gravid females oviposited in the offered furuncular lesions. Of 3242 eggs layed on botfly lesions (BFL), only 82 (2.5%) developed to second instar and died. In the flies tested, the furuncular lesions due to Dermatobia were used as food supply in 81.3% of the cases. In our opinion, the role of pH, the microflora associated with BFL, and the foruncular structure were the reasons for this lack of attraction. BFL do not serve as a predisposing factor for screwworm myiasis in the tropics.
在热带地区,人皮蝇(Dermatobia hominis)和新大陆螺旋蝇(Cochliomyia hominivorax)是牛身上最重要的蝇蛆病病原体。经常有报道称,人皮蝇引起的疖肿病变是螺旋蝇蛆病的一个诱发因素。我们的结果指出,在提供的疖肿病变中,只有5.2%至7.4%的新大陆螺旋蝇妊娠雌蝇产卵。在人皮蝇病变(BFL)上产下的3242枚卵中,只有82枚(2.5%)发育到第二龄并死亡。在测试的苍蝇中,81.3%的情况下,将人皮蝇引起的疖肿病变用作食物来源。我们认为,pH值、与BFL相关的微生物群以及疖肿结构是缺乏吸引力的原因。在热带地区,BFL不是螺旋蝇蛆病的诱发因素。
