Control of Face Flies and Horn Flies with Experimental Diflubenzuron Boluses, 1988
Insecticide and Acaricide Tests, 1989Abstract Two bolus formulations of 4.75 g (9.7% AI) flaked and powdered diflubenzuron were administered to beef cattle to test their efficacy against horn flies and face flies. Commercially available Vigilante° and methoprene boluses were used as standard treatments.

Control of Face Flies and Horn Flies With Experimental Ear Tags, 1988
Insecticide and Acaricide Tests, 1989Abstract Two experimental organophosphate ear tags (YT-802B1 and YT-607C3) were compared with 4 commercially available ear tags (Optimizer, Maxcon Super, Tomahawk, and Terminator) for efficacy against horn flies and face flies on beef cattle. Treatment effectiveness of all tags was compared against 3 untreated herds.

Effect of Horn Flies on Behavior of Cattle
Journal of Economic Entomology, 1982Activities of yearling steers that were treated or not treated for control of Haematobia irritans (L.) were recorded from direct observation. During the day, untreated steers spent more time walking and resting than did treated steers, and it appeared that they traveled ca. 0.5 km/day more than treated steers.

A Novel Resistance Management Strategy for Horn Flies (Diptera: Muscidae)
Journal of Economic Entomology, 1987Dispersal by horn flies, Haematoma irritans (L.), may have a significant impact on management of insecticide resistance. Recent discovery of extensive movement of horn flies between cattle herds separated by 0.05, 0.8, and 1.7 km is used as a basis for consideration of a new resistance management strategy for this pest.

Effect of Ivermectin on Survival and Fecundity of Horn Flies and Stable Flies (Diptera: Muscidae)
Journal of Economic Entomology, 1986Adult horn flies, Haematobia irritans (L.), and stable flies, Stomoxys calcitrans (L.), were fed on a blood diet that was fortified by the addition of known quantities of ivermectin [Merck MK933, at least 80% of 22,23-dihydro-5- O -demethylavermectin A10 and not more than 20% 22,23-dihydro-5- O -demethyl-25-de(1-methylpropyl)-25-(1-methylethyl ...

Ear Tags for Control of Horn Flies and Face Flies on Beef Cattle, 1981
Insecticide and Acaricide Tests, 1982Abstract Two types of cattle ear tags were evaluated for control of horn flies and face flies on beef cattle at The Pennsylvania State University Haller Farm. Six herds of mixed breeds on separate 1.5-1.8 acre pastures, each consisting of 4 cows with calves at their side were used to evaluate Ectiban (0.90 ai/tape, perraethrin) ear tapes

Biology and control of tabanids, stable flies and horn flies.
Revue scientifique et technique (International Office of Epizootics), 1995Tabanids are among the most free-living adult flies which play a role as livestock pests. A single blood meal is used as a source of energy for egg production (100-1,000 eggs per meal), and females of certain species can oviposit before a blood meal is obtained (autogeny). Therefore, the maintenance of annual populations requires successful oviposition

Stable-flies and horn-flies (bloodsucking Muscidae)
1993The Muscidae occur worldwide and include nearly 4000 species. The adults of most of them cannot bite and usually depend for their nutrition on a diet other than blood, but some among this huge number — about 50 species comprising the subfamily Stomoxyinae — are unusual muscids because they are able to bite with a specially adapted proboscis and feed by

Effects of Additives on the Toxicity of Pyrethrins to Stable Flies and Horn Flies
Journal of Economic Entomology, 1963Formulations containing various combinations of R-ll (2,3,4,5-bis(∆2-butylene)-tetrahydrofurfural), R-326 (di- n -propyl isocinchomeronate), MGK 264® ( n -(2-ethylhexyl)-5-norborneue-2,3-dicarhoximide), Tabutrex® (dibutyl suceinate), butoxy polypropylene glycol, and piperonyl butoxide with 0.02% pyrethrins and without pyrethrins were much less ...

Distribution of horn flies on individual cows as a percentage of the total horn fly population
Veterinary Parasitology, 2003Twenty-three mixed-breed herd cows were phenotyped for their ability to serve as a suitable host for Haematobia irritans, the horn fly. Based upon consistent observations within the lower quartile or upper quartile of individual fly counts, four cows were phenotyped as low carriers and five cows were phenotyped as high carriers of horn flies.
