Seasonal and weather factors influencing the annual flight cycle of Prostephanus truncatus (Coleoptera: Bostrichidae) and its predator Teretriosoma nigrescens (Coleoptera: Histeridae) in Benin
Bulletin of Entomological Research 87 (3), 239-246
Abstract: Investigations were carried out in southern Benin on the annual flight cycle and the effects of weather variables on the flight activity of Prosephanus truncatus and its natural enemy, Teretriosoma nigrescens. Two seasonal peaks in flight activity of P. truncatus were observed, one btween the end of December and the beginning of Janunary and a second one between May and June. T. nigrescens showed a single delayed peak, approximately six weeks aver the major peak of P. truncatus. Flight acticvity of P. truncatus was only weakly associated with weather characterstics, wheras for T. nigrescens it was associated with precipitation.
