Horn fly (Diptera: Muscidae) distribution on cattle as influenced by host color and time of day
Environmental Entomology 15 (6), 1307-1309
Abstract: Horn fly, Haematobia irritans (L.), counts were made on a group of cattle in the sandhills of Nebraska over a 2-year period. Counts on both sides of cattle were made three times a day, twice weekly on 10 black/white-face cattle and 10 red/white-face cattle. Analysis indicated that a significantly higher number of flies was observed on black/white-face cattle than on red/white-face cattle. Also, a circadian pattern of horn fly distribution was observed. In the morning, the majority of flies were found on shoulders, sides, and belly midline, and in the afternoon flies were concentrated on belly midline and sides. Flies returned to shoulder areas again at dusk.
