Modulation of the temporal pattern of calling behavior of female Spodoptera littoralis by exposure to sex pheromone
(2012) In Journal of Insect Physiology 58. p.61-66- Abstract
- We have examined the timing of calling behavior in the female Egyptian cotton leafworm, Spodoptera littoralis and its modification by exposure to sex pheromone. The calling rhythm of the female moth was found to be circadian, persistent for at least 4days once it has been entrained, and could be phase shifted by altering the light:dark regime. We also found that female exposure to pheromone affected the rate and duration of calling. A brief exposure to pheromone gland extract increased the proportion of females calling in a constant dim light and this effect persisted for at least 2days. In response to pheromone exposure, significantly more females also called late into scotophase when most unexposed control females had ceased... (More)

The adaptive significance of responding to conspecific sex pheromone is discussed. (Less)
