Research in Artificial Diet for Multi-Generation Rearing of Papilio xuthus

From the view point of coevolution of Papilio xuthus L. (Lepidoptera:Papilionidae) and its hosts, and based upon the feeding behavior and digestive characteristics, three artificial diets were developed in the rearing program of thrarthropod. Evaluation of the pupal weight showed that diet No.3 was the best for rearing Paplio xuthus L. for four generations: mean pupal weight of larvae feeding on the diet was significantly higher than those feeding on citrus leaves in each generation, and the larval survival rate was significantly higher on diet No.1 and diet No.2.
