[NO-synthase inhibitor prevents flight-induced activation of agressiveness and courtship in male].
Previous experience of flying enhances the aggressiveness (Hofmann and Stevenson, 2000, Nature, 403: 613) and accelerates the courtship behaviour (Dyakonova and Krushinski, 2003, DAN, 390: 709-712) of crickets Gryllus bimacultus. We present evidence that these effects may be mediated by activation of nitric oxide synthesis. The effects of flying on fighting and courtship were largely abolished in crickets who received haemocoel injections of a nonspecific NO-synthase inhibitor LNNA. Unlike this, LNNA exerted no significant effects on aggressive and courtship behaviour of nonflown males.
