中文摘要：采用室内多对脱翅成虫群养的方法对黑胸散白蚁群Reticulitermes chinensis Snyder体产卵及孵化行为进行观察。结果表明：多对脱翅成虫群养，黑胸散白蚁表现出群居行为，会共同产卵、护卵；1～5对脱翅成虫群养的产卵历期分别为9.00，8.25，8.17，7.33，7.13 d；孵化历期分别为36.67，39.33，31.33，35.88，36.33 d；经分析差异均不显著。在1～4对脱翅成虫群养范围内，群体产卵成功率随原始脱翅成虫配对数量的增加而升高；4～5对产卵成功率比1～2对的显著要高（P<0.05）。
英文摘要：Oviposition and hatching behavior of Reticulitermes chinensis Snyder were observed with the method of group rearing of several couples of dealate adults in laboratory. The results showed that R. chinensis displayed gregarious behavior, in which they oviposited and protected eggs together. The oviposition duration of 1 to 5 pairs dealate adult group were 9.00, 8.25, 8.17, 7.33, and 7.13 d, respectively, and hatching duration were 36.67, 39.33, 31.33, 35.88, and 36.33 d, respectively. There were no significant differences between treatments. In the range of 1 to 4 pairs dealate adults, oviposition success rate of each group increased with the pairing number of original adults. The oviposition success rate of 4 to 5 pairs adults was significantly higher than that of 1 to 2 pairs adults (P<0.05).
