Abstract
In order to characterize the nature of Periplaneta austyalasiae, sex pheromone, interspecific behavioral and EAG tests were carried out using both P. austyalasiae and P. americana. A highly purified P. austyalasiae sex pheromone (G-7) was obtained for the tests and used together with P. americana sex pheromones [periplanone-A (PA) and periplanone-B (PB)]. Male P. austyalasiae positively responded to G-7 and PA, but not to PB in both tests. Male P. americana also behaviorally and electrophysiologically responded to G-7 as well as to his own pheromones. Owing to these results, P. austyalasiae sex pheromone was suggested to be a PA-like substance.
