Immunization of Bovines with Concealed Antigens from Haematobia irritans

Annals of the New York Academy of Sciences, 2004
Abstract: To evaluate an immunization procedure using antigens from Haematobia irritans intestine (AgHiI), four bovines (group I) were inoculated with AgHiI mixed with Freund's incomplete adjuvant containing Lactobacillus casei, three bovines (group II) received AgHiI, and three bovines (group III) received saline solution.

Acetylcholinesterase mutation in diazinon-resistant Haematobia irritans (L.) (Diptera: Muscidae)

Veterinary Parasitology, 2008
Acetylcholinesterase (AChE) cDNA from individual field-collected diazinon-resistant horn flies was amplified by RT-PCR. Sequencing of the amplification products revealed that 8/12 of the diazinon-resistant horn flies contained a point mutation previously associated with resistance to organophosphates in house flies and Drosophila, strongly suggesting ...

Status of Haematobia irritans (Diptera: Muscidae) Insecticide Resistance in Northeastern Mexico

Journal of Medical Entomology, 1995
Horn fly, Haematobia irritans (L.), populations in northeastern Mexico were surveyed for resistance to fenvalerate and coumaphos. Compared with a susceptible strain of horn flies, resistance levels among field populations for the pyrethroid, fenvalerate, ranged from 36 to 199 times at the LD50 level, indicating that horn fly control with pyrethroids ...

Commingled black and white cows (Bos taurus; Angus and Charolais) in high-elevation rangeland are differentially parasitised by Haematobia irritans

Animal Production Science, 2019
Globally horn flies (Haematobia irritans) are one of the most economically damaging parasites of beef cattle. These obligate blood-feeding external parasites take blood meals from cattle leading to blood loss, annoyance avoidance behaviours, and ...

Skin lesions and cattle hide damage from Haematobia irritans infestations

Medical and Veterinary Entomology, 1999
Summary The horn fly Haematobia irritans L. (Diptera: Muscidae) has recently spread to Argentina and Uruguay and is believed to cause damage to cattle hides. Four groups of ten Holstein steers each were maintained for 58 weeks under different infestation levels with

Population dynamics of horn fly, Haematobia irritans irritans (L.) (Diptera: Muscidae), on Hereford cattle in Uruguay

Veterinary Parasitology, 2008
Abundance of adult horn flies, Haematobia irritans irritans (L.), was monitored on 25 untreated Hereford cows in Tacuarembó Department, Uruguay, during three consecutive grazing seasons, from October 1999 to May 2002. The population showed a variable pattern of abundance during three years, with peaks in late summer-early fall of each year. Adult flies

Morphological aspects of the third instar larva of Haematobia irritans

Medical and Veterinary Entomology, 1987
Abstract. The main morphological features of the cephalic region of the larva of Haematobia irritans (L.) are the oral grooves, tripartite labium and the antennomaxillary protuberances that have the dorsal, terminal and ventral sensory organs.

Feeding Haematobia irritans (Diptera: Muscidae) Adults Through a Nylon-Reinforced Silicone Membrane

Journal of Medical Entomology, 1993
A nylon-reinforced silicone membrane used to feed Haematobia irritans (L.) adults was found to be equally effective as the currently used blood-soaked cotton method. Membranes consisted of nylon bridal veil embedded in a thin layer of clear silicone caulk prepared by pressing bridal veil and silicone caulk bead between two brass rollers, using Parafilm

Influence of selective treatment of bulls on the infestation of Haematobia irritans on untreated cows.

Veterinary parasitology, 2018
The distribution of Hematobia irritans is not homogeneous in cattle populations. Generally, between 15% and 30% of bovines carry more than 50% of the flies, and higher infestations occur in bulls.
