During 1981—1984,464 chickens were examined by autopsy,and 65 of them(16.3%)appeared to be infected with Raillietina tetragona in Xiamen. Through our laboratory infections and dissection of ants collected from the natural farm houses in the suburb of Xiamen,it was found that ant, Leptothorax sp.,can act as the intermediate host of T.tetragona both in the laboratory and in the natural farms.The natural infection rates were 1.4%(29/2195).The rice beetle,Tribolium ferrugineum,could not serve as the intermediate host of R.telragona experimentally. At room temperature ranging from 28—30℃,the larval development of R.tetragona from egg to a mature cysticercoid in ant takes 17—19 days after infection.The adult worm containing gravid segments was found in chicken on the 15th day after infection,but the gravid proglottids were seen in the host feces 21 days after feeding cysticercoids. As shown by our experiment,the larval development of R.tetragona was similar to that of R.cesticillus.Its developing pattern could be divided into five stages,e.g.(1)oncosphere stage,(2)lacuna stage,(3) cystic cavity stage,(4)scolex formation stage and (5)cysticercoid stage.The mature cysticercoid is oval,measuring 345—389×216—281μ in size. The cystic wall consists of three layers.The outer cuticle is transparent and 5—5.5μ thick.The middle layer is composed of parenchymous cells, with 21—40μ in thickness.The inner layer is fibrous,measuring 5.3—9μ in thickness.The scolex is oval in shape,with 90—100 rostellar hooks, arranging in a single row.Suckers have 5—6 rows of spines.There are numerous calcarous granules distributing between the scolex and cyst wall. The caudal appendage is smalland oval in shape,ordinarily disappeared from the end of cysticercoid stage.
