VPA 221: Veterinary Entomology and Acarology (1+1)

CONTROL - HORSE FLY

• Very difficult since they fly far from their breeding areas

Adults

• Residual sprays of malathion on the shed walls
• Since the fly skims over water kerosene on water was used earlier to control the flies
• Ear tags with cypermethrin are effective
• Avoid the sunny parts of the day for grazing the animals
• Traps which are coloured black can be  placed near breeding areas to trap tabanids

Immature stages

• Biological control using hymenopteran insects such as Hunterellus hookeri and ants such as Telenomus spp., which  feed on the eggs of tabanids
