Studies were conducted on the effect of age and sex on the response of Prostephanus truncatus (Horn) to its male-produced pheromone using a laboratory walking bioassay. P. truncatus adults responded to pheromone from two days of age, but the level of response significantly decreased gradually from 2-10 days of age: newly-emerged, younger beetles seemed to respond more quickly and stay longer in the vicinity of pheromone source than older beetles. There was no significant effect of sex in the level of response to pheromone. The results are discussed in relation to the function of the pheromone: a feeding-based role. The practical implications of the findings on the pest's monitoring using pheromone-baited traps are also highlighted.
