Behavioural differences between male and female replacement reproductives in Kalotermes flavicollis (Isoptera, Kalotermitidae)

Abstract

An ethogram type study was performed on representative colonies of Kalotermes flavicollis to investigate the behavioural repertoires of replacement king and queen. Our observations suggested a sex-based behavioural specialisation in the two reproductives, affecting colony organisation and equilibrium. Interesting differences were detected in overall activity of the two reproductives, with the male showing the greatest frequency of movements in the nest, vibratory acts, and the highest rate and range of social contacts. In addition to his importance for periodical insemination of the queen, the king might also play a basic role in the social structure and dynamic development of the colony, as a “mediator” in social interactions between the queen and the other colony members.
