title: Social aggressiveness of female and subordinate male crickets is released by opiate receptor antagonist.
abstract: 1. In the cricket Gryllus bimaculatus, effects of opiate receptor antagonist naloxone, 9 or 30 microg per animal, on aggressive behavior were investigated. 2. Naloxone had no significant impact on aggression of isolated and dominant males. In contrast, the drug caused a dramatic release of social aggression in female and subordinate male crickets. 3. The results suggest that activity of the opioid system contributes to suppress aggression in subordinate males, as well as in females, during social contacts.
