Circadian rhythmicity and development of the behavioural response to sex pheromone in male brown-banded cockroaches, Supella longipalpa (original) (raw)

The effects of age, time of day and pheromone concentration the responsiveness of the male brown-banded cockroach, Supella longipalpa (F.), to female volatile pheromone examined. Male response increased with age and peaked 10 days after the imaginal moult. A diel periodicity of responsiveness observed, with greater responses in the scotophase. The behavioural response dosedependent and its diel periodicity most obvious when intermediate pheromone concentrations (e.g. 0.01 female equivalents) used.
