Poultry Red Mite

• • Poultry red mite (PRM) is the predominant ectoparasite of laying hens across the world
  • Infestations can occur in every sort of housing system and affects commercial egg producers and backyard flocks
  • PRM infestation leads to reduced hen welfare
  • Mites feed at night causing irritation, leading to restlessness and stress behaviours such as increased aggression, pecking and cannibalism
  • PRM is involved in disease transmission in a range of both viral and bacterial diseases
  • PRM is a health hazard to humans causing mite dermatitis and may have the potential to transmit a variety of zoonotic diseases
  • PRM infestation leads to production losses such as downgraded eggs
  • Biosecurity is important in preventing PRM spread both between farms and within farms
  • Monitoring PRM populations is key to efficient control
  • Integrated pest management (IPM) has the potential to lead to sustainable and efficient PRM control
  • Studies have shown that early intervention with treatments is more effective at suppressing PRM populations that waiting for mite populations to reach damaging levels
  • Rotating pest control treatments is important to prevent resistance developing in PRM and other arthropod pests

Current interests and future aims:

• Vaccine development
• Genome sequencing
• Developing new ways to measure the effectiveness of vaccines and novel therapies addressing the 3Rs principles
• Understanding the chemical cues that mites use to find hens and aggregate
• Understanding resistance to current chemical control methods

Members of our poultry red mite research team interact with the UK’s largest poultry-devoted veterinary practice St. David’s Poultry Group and with local, national and international egg producers through direct visits, meetings, presentations and through the British Egg Industry Council and the British Egg Marketing Board Trust.

Our scientists regularly give talks and Moredun events and roadshows.  Please see our events page for any forthcoming activities in this area or if you would like to arrange a speaker for an event please contact The Moredun Communications Team.

Our scientists are also members of the EU COST Action FA1404 “COREMI” which promotes the improved understanding and research for sustainable control of the poultry red mite through co-operation and multidisciplinary networking between scientists and other stakeholders from different member states and from different disciplines.
