BIOMETRIC AND MOLECULAR CHARACTERIZATION AND JUVENILE DEVELOPMENT STAGES OF XIPHINEMA VULGARE TARJAN, 1964(NEMATODA, DORYLAIMIDA)

Morphometric and molecular studies were undertaken of Floricliari populations of Xiphineiwn LIIL/- gn?-e Tarjan, 1964. Al1 populations were found to be almost morphometric:rlly identica1 witli the type populations and those frorii Siìo Tomé. Juveniles were clearly separated in four developmental stages. Isoelectricfocusing profiles of specimen extracts stainecl for superoxide dismutase activity showed one or two close bands at pH 7.6 and 7.6/7.3, respectively. The PCR products of the ITS region was between 1 and 1.5 kb 2nd was digested by six restriction enzymes
