Abstract

Pheromone transfer particles (PTPs) found in the male alar pouch of the genus Tirumala serve to make females recognize their mates and there is a possibility that the chemical composition of the pheromone is species specific. In order to evaluate this possibility, the microstructure of PTPs for seven species of Tirumala was compared using a scanning electron microscope. PTPs of T. gautama, choaspes, ishmoides, septentrionis and hamata are, though slightly different in shape, almost rounded. On the other hand, those of T. limniace and T. petiverana are characteristically polyhydric in shape and a little smaller in size. There is a possibility that the characteristic microstructure of PTPs in individual Tirumala species reflects the clear sexual isolation.
