Management
Life cycle
- After mating the female fly will leave the animal to deposit eggs in fresh cattle manure. Eggs hatch within one week, and larvae feed and mature in the manure, pupating in the soil beneath the manure pat. Newly emerged horn flies can travel several miles searching for a host. The entire life cycle can be completed in 10 to 20 days depending upon the weather. The life cycle of the stabl…
Effects
- Economic losses associated with horn flies are estimated at more than $1 billion dollars annually in the United States. Horn fly feeding causes irritation, blood loss, decreased grazing efficacy, reduced weight gains, and diminished milk production in mother cows. Additionally, horn flies have been implicated in the spread of summer mastitis. Studies conducted in the U.S. and Cana…
Prevention
- Backrubbers and dust bags are an effective way to reduce horn fly numbers if cattle are forced to use them. Oral larvicides prevent fly larvae from developing into adults. An important factor when using an oral larvicide is insuring steady consumption. An additional complicating issue using an oral larvicide is horn fly migration from neighboring u...
Use
- The Vet Gun applies an individual capsule of insecticide to an animal and can provide control between 21 and 35 days.
Description
- Face fly adults closely resemble house flies except they are slightly larger and darker than the house fly. The face fly is a non-biting fly that feeds on animal secretions, nectar and dung liquids. The adult female face flies clustering around an animals eyes, mouth and muzzle, can cause extreme annoyance (Figure 2 http://go.unl.edu/9beh). Face flies will also feed on blood and othe…
Distribution and habitat
- Face flies are present throughout the summer but populations usually peak in late July and August. Face flies are most numerous along waterways, areas with abundant rainfall, canyon floors with trees and shaded vegetation, and on irrigated pastures.
Clinical significance
- Female face fly feeding causes damage to eye tissues, increases susceptibility to eye pathogens, and vector Moraxella bovis, the causal agent of pinkeye or infectious bovine keratoconjuctivitis. Pinkeye is a highly contagious inflammation of the cornea and conjunctiva of cattle. If coupled with the infectious bovine rhinotrachetis (IBR) virus, M. bovis can cause a much more severe infl…
Diet
- Stable flies are serious pests of feedlots and dairies and of pasture cattle. The stable fly is a blood feeder, mainly feeding on the front legs of cattle, staying on the animal long enough to complete a blood meal (Figure 3 http://go.unl.edu/y0of). Their bites are very painful; cattle will often react by stomping their legs, bunching at pasture corners, or stand in water to avoid being bitten.
Habitat
- The female stable fly deposits eggs in spoiled or fermenting organic matter mixed with animal manure, soil and moisture. The most common developing sites are in feedlots or dairy lots, usually around feed bunks, along the edges of feeding aprons, under fences, and along stacks of hay, alfalfa and straw. Grass clippings and poorly managed compost piles also may be stable fl…
Benefits
- Stable flies cause similar weight gain losses to both pasture and confinement cattle. University of Nebraska research, recorded a reduction in average daily gain of 0.44 lbs. per head with animals which received no insecticide treatment compared to animals which received a treatment. The economic threshold of 5 flies per leg is often exceeded in Nebraska pastures.
