Abstract: The morphological traits and biological characteristics of Graphium sarpedon were observed to provide some measures for IPM base on rearing indoor and field investigation. The results were as follows：There were broadly distributed host plant species infested by G. sarpedon in Fuzhou. The ornamental effect of ornamental trees such as C. camphora or C. cassia, were reduced due to leaves infestation of G. sarpedon larvae. This pest had 5 generations per year in Fuzhou and obviously overlapping generations with over-wintering pupa,the duration of one generation was 60.5 d while that of overwintering generation was 136.5 d. The mean duration of eggs was 5 d,and only single egg was laid by female moth on the younger leaf of C. camphora. Larvae had five instars with the mean duration 26~30 d,and feeding capacity increased with larval instar. Pupal stage approximately experienced 16 d while the overwintering duration of pupae was about 92 d on the leaf back. The longevity of moths was 8~11 d with 87.5% eclosion rate. To provide some helpful information for integrated pest management,life cycle table was made based on the dynamics of C. camphora in Fuzhou. In addition,there was roughly eight percent dead caterpillars partially due to entomopathogenic disease and parasitization by Brachymeria lasus Walker,which had 3% of natural parasitism rate,and both biotic factors played important roles to suppress population of C. camphora.
