Abstract: The life history of Eulaelaps stabularis includes five stages:ovum,larva,protonymph,deutonymph and adult.However,oviposition is very rare with no vitality,so the mites are ovoviviparous and produce larva or protonymph.The constantly accumulating effective temperature and the developmental zero of the stages are as follows:larva,11.53 day-degree and 6.27 ℃;protonymph,38.87 day-degree and 9.36 ℃,deutonymph,48.14 day-degree and 7.92 ℃.The proper temperature point may lie in between 20-25 ℃.The mating behaviour can occur when they become adults.The mating process of both sexes and larviposition mode was viewed carefully.The parthenogenesis has never been dicovered.Even if they do not desire food for a period but can live a long life.
