An electrically powered air sampler for collecting mites

Abstract The Cutler sampler, an electrically powered suction device for obtaining mites from air or surface dust is described. Mite numbers in air inside cattle byres ranged from 417 to 611 per 1000 litres of air while hay was tossed into mangers during cattle feeding. Mites were still present in air one hour after hay tossing. The numbers of mites per gram recovered from bed dust ranged from 35 to 4000 but were usually between 300 and 800.
