Abstract

This study was aimed to determine abundance and body distribution of PRM in laying hens of Arak. A total of 1400 laying hens were randomly examined from January to June 2008. Of those, 26 (92.86%) layer farms were found to be infested with Dermanyssus gallinae (39.3%). There was significant association between prevalence and climatic conditions of the region. The most common predilection site of PRM was significantly cloak (52.7%) and the highest mixed infestation rate was 10.9% for wing-breast and cloak-breast of examined poultries. It was concluded that PRM infestation was low and predilection sites of infestation may affect egg laying capacity.
