Histerid beetles (Coleoptera): survey and seasonality on poultry manure in caged layer hensThe species composition and the seasonality of histerid beetles were studied in Monte Mor (SP) from September 1992 to September 1993 at 15 d. intervals using pitfall-trap and Berlese's funnel. Seven species of histerid beetles were recorded: Euspilotus modestus Erichson, Carcinops troglodytes Paykull, Euspilotus (Hesperosaprinus) sp., Hololepta quadridentata Fab., Hister dubius Mars., Acritus sp. and Phelister sp.. E. modestus (52%) and C. troglodytes (33%) were the most abundant. They showed the highest association (1) of Whittaker & Fairbanks index. The sampling methods had a direct influence on the numbers of beetles, principally, to E. modestus and C. troglodytes.
