[The behavioral responses of Spodoptera litura (F.) males to the female sex pheromone in wind tunnel and field trapping tests]
Acta Entomologica Sinica 46 (1), 126-130
Abstract: The major component of the sex pheromone of S. litura (F.) female, Z9, E11-14: Ac (A), elicited all steps of the male behavioral sequence, i. e. , searching for the odor, oriented upwind flight, approaching the source and displaying hairpencils. No males showed oriented flight when Z9, E12-14:Ac (B), Z9-14: Ac (C)., E11-14: Ac (D) were assayed individually. Component B was able to enhance the activity of A, but larger amount of B in mixture strongly inhibited males from approaching the source and displaying hairpencils. The components of C and D had no effect on male behavior, but larger amount of C in a mixture of A and B inhibited males approaching the source and displaying hairpencils. There was a significant difference between the ratio of A to B in the filter paper lure and that in volatile from the filter paper lure. The ratio of A to B in volatile from the most effective lure in the wind tunnel was approximate to the natural ratio of A to B in the sex pheromone gland. In the field, the attractiveness of trap for male moths changed with the ratio of the components with most males being caught in traps baited with a ratio of 9 : 1 (A: B) . The attractiveness of traps with ratios of 1: I ( A : B ) was lower than the attractiveness of traps baited with single component A.
