Abstract
The factors that regulate male aggressive behavior towards females during the mating season and their relationship to the sexual behavior of Japanese monkeys were investigated. Observations were made on the Shiga A troop in Nagano Prefecture for 132 days during both the non-mating and mating seasons in three successive years. As a result, chasing towards females was observed in males older than 4 years. The frequencies of this type of behavior increased in the mating season. The chasing rank of the individual males did not correlate with the male dominance rank but with the tree-shaking rank. Chasing was directed not only at estrous females but also at non-estrous females. Pairs of both sexes in which chasing was observed, tended to have sexual interactions. Both hormonal and social factors should be considered in the regulation of chasing. The role of aggression in the formation of new male-female bonds in discussed.
