A survey was conducted during 1980 and 1981 to determine seasonal incidence of hog lice, Haematopinus suis (L.), and sarcoptic mange mites, Sarcoptes scabiei (De Geer), in market-weight swine in Indiana. The survey indicated that infestations of both lice and mites were higher during cooler months. Over the course of the survey, hog lice and mange (itch) mites were present on 18.1 and 25.3% of all animals examined, respectively. Animals confined in small pastures had higher incidences of lice than animals in totally or partially confined systems, although confinement type did not affect incidence of mite infestation. Results of a questionnaire sent to Indiana veterinarians concerning these pests are discussed. Responding veterinarians estimated a 51.5% incidence of hog lice and 36.2% incidence of sarcoptic mange mites on farms visited. Veterinarians did not notice correlations between lice or mange and confinement type, animal breed and age, or geographical area. Results of questions asking the veterinarians treatment methods preferred and importance of these parasites are presented.
