In the field, the female horn fly obtained blood meals from the bovine host before oviposition. The female flies moved to the lower portion of the hind legs as the legs were spread, and the tail was raised before excretion. Females deposited their eggs on the manure after excretion. The fly flew onto the manure pat for oviposition as the cow walked forward after excretion. It appeared that flies located on the belly received some stimuli for oviposition from the cow just before excretion. The horn fly deposited most of its eggs during the day with occasional deposition at night. Egg deposition increased at 10 degrees C. Fewer flies were observed on manure pats that contained >90% or <84% water. The location of horn flies on the cow and environmental factors associated with oviposition in the field are discussed.
在野外，雌性角蝇在产卵前从牛宿主获取血餐。当牛腿展开时，雌性苍蝇移到后腿下部，在排泄前尾巴会抬起。雌性苍蝇在排泄后将卵产在粪便上。当牛排泄后向前走时，苍蝇会飞到粪堆上产卵。似乎位于牛腹部的苍蝇在牛即将排泄前受到了一些产卵刺激。角蝇大部分卵在白天产下，偶尔在夜间产卵。在10摄氏度时产卵量增加。在含水量>90%或<84%的粪堆上观察到的苍蝇较少。本文讨论了角蝇在牛身上的位置以及野外与产卵相关的环境因素。
