| Summary: | [ Objectives ] To study the reproductive behaviors and the effect of different pairing modes on the developmental status of incipient colonies＇of Odontote- rmes fomosanus （Shiraki）. [ Methods ] We observed the reproductive behaviors of male alates, female Mates and mated alates respectively. Male and female Mates had 9 pairing modes and founded 170 incipient colonies under laboratory conditions. The effect of pairing mode on incipient colonies＇ developmental status was ana- lyzed. [ Results ] Two peaking hours of mating activity within the daily circadian rhythm of Mate 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 signifi- candy longer than that of alates paired with siblings （P 〈 0.05 ）. The non-swarming alates could mate with swarming or non-swarming Mates and lay fertile eggs which hatched successfully. However, the survival rate of colonies 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 colonies 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 founded by outbreeding have the highest probability of survival. |
