中文摘要： 扩头蔡白蚁Tsaitermes ampliceps （Wang & Li）和黑翅土白蚁Odotoermes formosanus (Shiraki)是分布广泛的食木性昆虫，群居生活，具有复杂的品级分化。本试验研究了低等白蚁扩头蔡白蚁不同品级的消化和生殖系统结构，并与高等白蚁黑翅土白蚁进行了比较。结果显示扩头蔡白蚁的消化、生殖系统结构与后者相似。2种白蚁工蚁的嗉囊、囊形胃的长度和宽度明显比其它品级大，工蚁的中肠和结肠均比兵蚁短，且差异显著（P<0.05）；扩头蔡白蚁工蚁的嗉囊、前胃和囊形胃的长度和宽度明显大于黑翅土白蚁（P<0.01）。扩头蔡白蚁生殖蚁的侧输卵管直径与长度的比例和输精管直径与长度的比例明显大于黑翅土白蚁（P<0.01）。
英文摘要： The woodfeeding, social termites Tsaitermes ampliceps (Wang & Li) and Odontotermes formosanus (Shiraki) have complex caste differentiation. The digestive and reproductive systems of different castes of the more primitive T. ampliceps were studied and compared to those of the more advanced O. formosanus. The results show that the digestive and reproductive systems of these species have a similar structure. The crop and paunch of workers are significantly longer and wider than those of other castes (P<0.05) and the midgut and colon of workers are significantly shorter than those of soldiers (P<0.01). The crop, proventriculus and paunch of workers in T. ampliceps is evidently longer and wider than in O. formosanus (P<0.01). The ratio of the diameter and length of the lateral oviduct and seminal duct of reproductive individuals in T. ampliceps was larger than in O. formosanus (P<0.01).
