Habituation of the response to sex pheromone in two species of lepidoptera, with reference to a method of control
1970
TRAYNIER, R.M.M.
The rate of habituation of male Anagasta kuehniella to sources of sex pheromone at four different concentrations (10⁻⁴--10⁻¹ female equivalents of extract) was measured at the time of their diel peak of responsiveness. While the level of response to pheromone increased with concentration, the rate of habituation seemed to be independent of concentration provided this was above the threshold level for response. An interpretation of some data obtained with Trichoplusia ni by Shorey et al. yielded a similar conclusion: the rate of habituation of the response to pheromone was not greatly affected by changes in concentration. The relevance of these findings to the design of control measures for Lepidoptera is discussed.
