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

Status of Haematobia irritans (Diptera: Muscidae) Insecticide Resistance in Northeastern Mexico
Journal of Medical Entomology, 1995Horn 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 ...

Feeding Haematobia irritans (Diptera: Muscidae) Adults Through a Nylon-Reinforced Silicone Membrane
Journal of Medical Entomology, 1993A 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

Experimental Parasitology, 2004
The fly Haematobia irritans irritans is one of the most important ectoparasites in cattle production, due to its ability to suck large amounts of blood. This report describes the purification and characterization of a serine proteinase inhibitor (HiTI) present in H. i. irritans head and thorax extracts.
