The reduction in number and e Y cacy of many acaricide products has accentuated the prevalence rates of this poultry ectoparasite observed more often in non intensive systems such as free-range, barns or backyards and more often in laying hens than in broiler birds. The lack of knowledge from producers and the utilisation of inadequate, ine V ective or illegal chemicals in many countries have been responsible for the increase in infestation rates due to the spread of acaricide resistance. The costs for control methods and treatment are showing the tremendous economic impact of this ectoparasite on poultry meat and egg industries. This paper reviews the prevalence O.

Keywords Dermanyssus gallinae · Prevalence · Infestation rates · Control costs · Poultry Introduction Dermanyssus gallinae (De Geer, 1778) also known as the poultry red mite (PRM) or the poultry mite is an increasing epidemiological and economical problem for the poultry industry worldwide. This ectoparasite is a blood feeder and is responsible for egg down- grading and spotting, anaemia in birds and more reports suggest it could have a vector role for several human and animal diseases. It is the most important ectoparasite a V ecting laying hens (Chauve...
