Factors affecting pheromone production and behavioural responses by Prostephanus truncatus (Coleoptera: Bostrichidae)
Annals of the Entomological Society of America 91 (6), 872-878
Abstract: With a 4-arm olfactometer, we studied the pheromone production of male Prostephanus truncatus (Horn) and responses of both sexes to synthetic pheromone components. Single males and groups of males on maize were highly attractive to both sexes when the males had been separated from females for some days. Maize cultures infested with low numbers of males and females were slightly preferred, whereas cultures at high densities elicited no positive responses, Males on foamed polystyrene and on wood of Balanites aegyptiaca (L.) (Zygophyllaceae) evoked no positive re-sponses, but males on wood of Commiphora riparia Engl. and Commiphora africana (A. Rich.) (both Burseraceae) were as attractive as males on maize. Male and female P. truncatus always responded strongly to the synthetic pheromone. The responses of females were significantly greater than those of males; their response intensity was little affected by their state of activity before the experiment or by a previous extensive exposure to the pheromone. We discuss the results with respect to pheromone production strategies and control methods.
