Abstract
This study was conducted to determine the succession of necrophilous insects on sun and shade-exposed pig carrion. Twenty-two, seventy kilogram, clothed, fresh domestic pig carcasses (Sus scrofa L.) were monitored throughout decomposition in three rural areas in Manitoba during trials beginning in spring, summer and fall. A minimum of 13 arthropod orders, 61 families and 95 species collected manually and in pitfall traps over the duration of the study were identified. From this information, the arrival times and duration of stay were recorded for some of the most numerous species: Calliphora vicina Robineau-Desvoidy, Calliphora vomitoria (Linnaeus), Cynomya cadaverina(Robineau-Desvoidy), Lucilia illustris (Meigen), Phormia regina (Meigen) and Protophormia terraenovae (Roboneau-Desvoidy) (Calliphoridae); Prochyliza xanthostoma Walker, Stearibia nigriceps (Meigen) (Piophilidae); Necrodes surinamensis(Fabricius) and Oiceoptoma noveboracensis (Forster) (Silphidae); Creophilus maxillosus (Linnaeus) and Ontholestes cingulatus (Gravenhorst)aphylinidae); Necrobia rufipes (DeGeer) and Necrobia violacea (Linnaeus)(Cleridae); Glischrochilus quadrisignatus (Say) and Nitidula ziczac Say (Nitidulidae); Dermestes ater DeGeer,Dermestes fasciatus LeConte, Dermestes lardarius Linnaeus (Dermestidae); Trox unistriatus Beauvois (Trogidae); Geotrupes semiopacus Jekel (Geotrupidae) over the entire decay process. The Calliphoridae predominated in the carcasses during the fresh, bloat and decay stage
