Relation between Banding Patterns of Malic Enzyme by Electrophoresis and a Morphological Character in Exotic and Native Torymus Species

Relation between banding patterns of malic enzyme and a morphological character (ratio of length of ovipositor sheath to length of thorax) was investigated in Torymus species. In Torymus individuals that emerged from withered galls of Dryocosmus kuriphilus collected from five different localities in Japan, F or S type of banding patterns were detected. The morphological character indicated that there were two distinct groups in Torymus species : T. sinensis (large ratio group) and T. beneficus (small ratio group). The malic enzyme of T. sinensis was fixed on the S band while in T. beneficus only the F band was detected. Therefore, this enzyme is a useful hereditary index for investigating the interspecific competition and hybridization between these two closely related species.
