雄性赤拟谷盗（Tribolium castaneumHerbst）经常配对并试图与其他雄性交配。我们研究了男性以前的社会经验是否会影响他与其他男性配对的倾向。将未交配雄性动物以不同密度饲养（单独饲养，或与3只或7只雄性动物一起饲养），并在7、14或28天后进行检测。雄性在较高密度下进行的雄性-雄性配对行为较少，而在与其他雄性保持较长时间后进行的雄性-雄性配对行为较多。我们还让雄性在被隔离之前或之后与其他雄性的经验，发现雄性对雄性配对行为受到雄性最近社会经验的影响最大。最后，我们发现，被保持与女性降低了男性的后续趋势，与男性配对相对于那些以前保持与男性。总的来说，研究结果表明，男性获得的社会经验类型对他们未来是否会与男性配对有明显的影响。
Male red flour beetles (Tribolium castaneumHerbst) often pair and attempt to copulate with other males. We examined whether a male’s previous social experience affected his tendency to pair with other males. Virgin males were kept at different densities (singly, or with 3 or 7 males) and tested after 7, 14, or 28 days. Males performed fewer male-male pairing behaviors after being kept in higher densities and more male-male pairing behaviors after being kept with other males for longer periods of time. We also gave males experience with other males either before or after being isolated and found that male-male pairing behavior was most strongly influenced by a male’s most recent social experience. Finally, we found that being kept with females decreased a male’s subsequent tendency to pair with males relative to those previously kept with males. Overall, the results suggest that the type of social experience males acquire has a clear effect on whether they will pair with males in the future.
