Abstract:
Soil and root samples were collected from the rhizosphere of crops during the survey of plant nematodes in the main cultivation area in Tibet.Plant nematodes were isolated from these samples by using the modified Baermann funnel method.Based on morphological characteristics,three species,Pratylenchus loosi,P. neglectus and P. scribneri from genus Pratylenchus were identified.The P. loosi populations from Tibet has a shorter tail than those described in literatures.The main morphological characteristics and measurements of the P. neglectus and P. scribneri populations in Tibet were similar to those described in literatures.The P. neglectus was distributed in Nyingchi and Lhasa area,and the other two species were distributed in Nyingchi.
