Double‐sided sticky traps were baited with polythene vials containing synthetic components of the aggregation pheromone of Prostephanus truncatus (Horn) and used to investigate the effect of time of day on capture of this insect. P. truncatus exhibited a bimodal pattern of flight activity with a major peak between 18.00 and 21.00 h, and a smaller peak between 07.00 and 09.00 h. The effective life of the pheromone bait was also investigated over 33 days. The highest numbers of P. truncatus were caught during the first 8 days and the majority of the beetles were caught within 14 days. Catches then showed a steady decline. Captures of the predatory histerid Teretriosoma nigrescens Lewis, were much lower than those of P. truncatus and showed fluctuations which did not appear related to numbers of its prey. Environmental factors such as rainfall, temperature, wind and trap positioning appeared to influence results, especially when considered over a short time scale.
