Affinity in the Species of Paratylenchus (Tylenchida: Paratylenchidae)
Y. S. Rathore  | S. N. Tiwari 
Abstract: Host taxonomic affinity of 28 species of Paratylechus was examined and it was observed that, in general, this nematode tend to share 65.79 % host species from dicotyledons, 31.95 % mocotyledons and 2.26 % gymnosperms. Plants from lignosae division (fundamentally woody plants) contributed by 42.48 % and herbaceae (fundamentally herbaceous plants) only 23.31 %, almost half of the lignosae. Among families Fabaceae (Lrguminales), Rosaceae (Rosales), and Vitaceae (Rhamnales) were more contributing in lignosae, Asteraceae (Asterales) and Lamiaceae (Lamiales) in herbaceae, and Poaceae (Graminales) in glumiflorae of monocotyledons. Out of 28 species of Paratylechus, 12 were host specific or monophagous, 3 oligophagous and 13 polyphagous. Some of the polyphagous species feed on gymnosperms and on very primitive families of angiosperms.
