Abstract:      [Objectives]  To study the reproductive behavior and the effect of different pairing combinations on the developmental status of incipient colonies’of Odontotermes fomosanus (Shiraki). [Methods]  We observed the reproductive behavior of male alatesfemale alates and paired alates respectively. Male and female alates had 9 pairing modes and founded 170 incipient colonies under laboratory conditions. The effect of pairing modes on incipient colonies’ developmental status was analysed. [Results]  Two hours of peak mating activity within the 24-hour circadian rhythm of alate activity appeared from 09:00 to 10:00, and from 21:00 to 22:00, respectively. Courtship behavior before mating consisted of touching with antennae, connecting into a ring (head-to-end), and licking. The reproductive behavior (calling, pairing, tandem, mating and oviposition) of nestmate pairs was different to that of non-nestmate pairs. The pairing time of non-nestmate pairs was significantly longer than that of alates paired with siblings (P<0.05). The non-swarming alates could mate with swarming or non-swarming alates and lay fertile eggs which hatched successfully. However, the survival rate of nests founded by non-swarming alates was very low. The death rate of incipient colonies was in the range of 0.61%-0.99% after three months, while the death rate of the nests founded by swarming alates was in the range of 0.22%-0.58%. Females that had been experimentally prevented from mating could lay eggs, but the eggs did not hatch. [Conclusion]  There are two distinct hourly peaks of mating activity within each 24 hour period. Incipient colonies found by outbreeding have the highest probability of survival.
