Population Genetics And Gene Variation Of Stable Fly Populations (Diptera: Muscidae) In Nebraska, Allen L. Szalanski, David B. Taylor, Richard D. Peterson Ii
Population Genetics And Gene Variation Of Stable Fly Populations (Diptera: Muscidae) In Nebraska, Allen L. Szalanski, David B. Taylor, Richard D. Peterson Ii
David B. Taylor
Genetic variation in stable fly, Stomoxys calcitrans (L.),populations from Nebraska, Canada, and Texas was sampled. Four of 12 allozyme loci were polymorphic, with an average of 1.7 alleles per locus. Observed and expected heterozygosities were 0.086 and 0.070,respectively. Nei's genetic distance between populations averaged 0.001 and ranged from 0.000 to 0.005. Wright's F statistics revealed greater variation within than among populations. Allele frequencies were homogeneous among temporal samples from a single population. Polymerasechain reaction—restriction fragment length polymorphism (PCR—RFLP) analysis of 6.4 kb of the mitochondrial DNA genome with 16 restriction enzymes revealed no variation in stable fly populations from Canada, …
Sugar Feeding In Adult Stable Flies, David Taylor, Dennis R. Berkebile
Sugar Feeding In Adult Stable Flies, David Taylor, Dennis R. Berkebile
David B. Taylor
Adult stable flies (Stomoxys calcitrans L.) are known to feed readily on sugars in the laboratory. However, little is known concerning the extent of stable fly sugar feeding in wild populations. We examined the frequency of sugar feeding in stable flies collected on Alsynite sticky traps in rural and urban environments. In addition, stable flies were visually examined to determine whether blood was present in the gut. In laboratory studies, sugars were detectable with the anthrone technique in stable flies for ~3 d after being imbibed, and blood could be visually detected in the gut for 24-48 h after feeding. …
Economic Impact Of Stable Flies (Diptera: Muscidae) On Cattle Production., David Taylor, Roger Moon, Darrell Mark
Economic Impact Of Stable Flies (Diptera: Muscidae) On Cattle Production., David Taylor, Roger Moon, Darrell Mark
David B. Taylor
Stable flies, Stomoxys calcitrans (L.), are among the most damaging arthropod pests of cattle worldwide. The last estimate of their economic impact on United States cattle production was published 20 yr ago and placed losses at $608 million. Subsequently, several studies of effects of stable flies on beef cattle weight gain and feed efficiency have been published, and stable flies have become increasingly recognized as pests of cattle on pasture and range. We analyzed published studies and developed yield-loss functions to relate stable fly infestation levels to cattle productivity, and then estimated the economic impact of stable flies on cattle …
Substrate Properties Of Stable Fly (Diptera: Muscidae) Developmental Sites Associated With Round Bale Hay Feeding Sites In Eastern Nebraska, Brian J. Wienhold, David B. Taylor
Substrate Properties Of Stable Fly (Diptera: Muscidae) Developmental Sites Associated With Round Bale Hay Feeding Sites In Eastern Nebraska, Brian J. Wienhold, David B. Taylor
David B. Taylor
Residues at sites where stationary feeders were used to provide hay as supplemental forage for cattle during the winter are developmental substrates for immature stable flies, Stomoxys calcitrans (L.), in the central United States. Spatial patterns in physical (substrate depth, temperature, water content), chemical (pH, electrical conductivity [EClab], total nitrogen [N] and carbon [C], ammoniacal nitrogen [NH4-N], extractable phosphorus [P]), and biological (microbial respiration rate) substrate properties for two feeding sites were estimated and the correlations between these properties and adult emergence were characterized. Hay feeding sites had a circular footprint with residues extending ≈7m from …
Dewatered Sewage Biosolids Provide A Productive Larval Habitat For Stable Flies And House Flies (Diptera: Muscidae), Carl W. Doud, David B. Taylor, Ludek Zurek
Dewatered Sewage Biosolids Provide A Productive Larval Habitat For Stable Flies And House Flies (Diptera: Muscidae), Carl W. Doud, David B. Taylor, Ludek Zurek
David B. Taylor
Species diversity and seasonal abundance of muscoid flies (Diptera: Muscidae) developing in biosolid cake (dewatered biosolids) stored at a wastewater treatment facility in northeastern Kansas were evaluated. Emergence traps were deployed 19 May through 20 October 2009 (22 wk) and 27 May through 18 November 2010 (25 wk). In total, 11,349 muscoid flies were collected emerging from the biosolid cake. Stable flies (Stomoxys calcitrans (L.)) and house flies (Musca domestica (L.)), represented 80 and 18% of the muscoid flies, respectively. An estimated 550 stable flies and 220 house flies per square-meter of surface area developed in the biosolid …
