DIAPAUSE INDUCTION IN THE HORN FLY (DIPTERA: MUSCIDAE)

The Canadian Entomologist, 1994
AbstractLaboratory studies of diapause induction in the horn fly Haematobia irritans irritans (L.) indicated that the incidence of diapause was unrelated to daylength or the number of day–night cycles. Transfer experiments were conducted to estimate the beginning and end of diapause sensitivity and the required number of days for diapause induction. On

Influence of Monensin and Diflubenzuron on the Control of Immature Horn Fly and House Fly (Diptera: Muscidae) and Chemical Composition of Cattle Feces

Journal of medical entomology, 2022
Twelve Angus × Hereford crossbred heifers were used in a completely randomized design to evaluate the effects of monensin and diflubenzuron feed additives on horn fly (Haematobia irritans) (L.) and house fly (Musca domestica) (L.) immature development ...

Relationship of horn fly to face fly infestation in beef cattle

Journal of Animal Science, 1994
Horn fly and face fly counts (n = 394) taken on 194 beef cows representing seven breed groups were used to determine the effects of horn fly and face fly counts. Breed groups included were Angus (ANI and ANII), Chianina (CA), Charolais (CH), Hereford (HH), Polled Hereford (PH), and Red Poll (RP). The breed group designated ANI consisted of small-framed

Horn Fly (Diptera: Muscidae) Dispersal Among Cattle Herds

Journal of Economic Entomology, 1987
Dispersal of wild horn flies, Haematobia irritans (L.), from existing populations to fly-free cattle was studied in Louisiana and Kansas. Rates at which horn fliesinfested fly-free cattle placed sequentially, for 10-d intervals, at 0.05, 0.8, and 1.7 km from a source population, did not differ significantly and averaged 18 flies per side per animal per

Horn fly (Diptera: Muscidae) resistance to organophosphate insecticides

Veterinary Parasitology, 2001
Insecticidal ear tags impregnated with organophosphate (OP) insecticides were used each year from 1989 to 1998 at Rosepine, LA. Weekly fly counts were conducted to evaluate control efficacy of the treatments, and bioassays were conducted at least twice per year to measure fly susceptibility to OP and pyrethroid insecticides.

PSI-19 Plasma haptoglobin concentration as a potential biomarker for stress caused by horn fly infestation in lactating beef cows.

Journal of Animal Science
The horn fly parasite has a negative impact on cattle because of its irritating and painful bites, which can reduce animal performance and welfare due to the resultant stress.

Sequence and transcript expression of the super‐kdr locus of the horn fly, Haematobia irritans

Medical and Veterinary Entomology, 2020
In horn flies, Haematobia irritans irritans (Diptera: Muscidae) (Linnaeus, 1758), target site resistance to pyrethroids can be diagnosed by an allele‐specific PCR that genotypes individual flies at both the super‐kdr (skdr) and the knock down resistance (
