| S. latifascia and S. descoinsi are closely related species that occur sympatrically over limited areas in French Guiana. We examined allopatric populations, S. latifascia originating from Barbados and S. descoinsi from French Guiana. Studies on nocturnal activity cycles showed temporal partitioning of female calling behavior, male sexual activity, and mating behavior.S. descoinsi were sexually active in the first half of the scotophase whereas S. latifascia were sexually active in the second half. Seven compounds (Z9–14: Ac,Z9,E12–14: Ac,Z11–16: Ac,E9,E12–14: Ac,Z9–14: Ald,Z9,E11–14: Ac andZ11–14: Ac) were identified in females of both S. latifascia and S. descoinsi extracts.Z9–14: Ac was a main pheromone component for the two species. The major difference... |
