Abstract:
The Malpighian tubules of adult Teleogryllus emma and Atractomorpha sinensis, which belong to Ensiera (Orthoptera) and Caelifera (Orthoptera) respectively, were observed using routine histological techniques. Distinct differences in the place and form of insertion and the cellular structures were found. Regarding the insertion point, the Malpighian tubules of T. emma arise near the junction of the anterior and posterior hindgut, however the Malpighian tubules of A. sinensis originate at the junction of the midgut and hindgut. Regarding the insertion form, the Malpighian tubules of T. emma are connected to the digestive tract through a colorless transparent common canal, however the Malpighian tubules of A. sinensis are divided to twelve clusters, with each cluster connected to the digestive tract directly. The tube wall of T. emma consists of eight cells, which are in the center of the canal and there is a gap with the tube wall. However the tube wall of A. sinensis consists of three or four cells, which are scattered in the canal, and possess the ampulla of Malpighian tubule in A. sinensis.
