雄性蟋蟀（Gryllus interger;直翅目：蟋蟀科）发出攻击性的鸣叫声，并为争夺雌性而激烈战斗。我们研究了男性对男性的攻击性受昼夜时间、性成熟、年龄和体重影响的程度。在年龄和/或体重匹配的男性之间观察试验，这些男性以前没有接触过彼此。数据收集攻击潜伏期，侵略性的鸣叫，时间花在侵略性的互动和赢家的审判。攻击行为在白天和晚上的任何时候都有可能发生。性成熟的雄性比尚未产生精荚的成年雄性更具侵略性。年龄过去性成熟并没有很大的影响侵略，重的男性比轻的更具侵略性。在相同的雄性之间的重复试验中，每对中的一只雄性赢得了更多的比赛。
Male field crickets (Gryllus interger; Orthoptera: Gryllidae) stridulate aggressively and fight vigorously in competition for females. We studied the degrees to which male-male aggression is influenced by time of night or day, sexual maturity, age and weight. Trials were observed between males matched for age and/or weight that had not previously been exposed to each other. Data were gathered on attack latency, aggressive stridulation, time spent in aggressive interactions and the winner of a trial. Aggression was equally likely to occur at any time of the day or night. Sexually mature males were more aggressive than adult males which had not yet produced a spermatophore. Age past sexual maturity did not greatly influence aggression, and heavy males were more aggressive than lighter ones. In repeated trials between the same males, one male in each pair won significantly more contests.
