- Fransius Simanjuntak, The Biodiversity Of Plant Parasitic Nematodes On Coffea Crop (Coffea sp) At North Sumatera. Supervised by Lisnawita and Lahmuddin Lubis. The research was conducted to determine biodiversity of plant parasitic nematodes associated with the soil and root of coffea in Dairi and Simalungun, three locations in Dairi and three locations in Simalungun. Survey was using random sampling for soil and root and using corong Baerman modification for plant parasitic extraction at Plant Disease Laboratory, Plant Pest and Disease Department, Agriculture Faculty, USU from May to September 2010. Based on this survey two genera of plant parasitic nematodes where encountered in Dairi and Simalungun. Plant parasitic nematodes included Radopholus spp and Pratylenchus spp were most distributed with population densities varying from low to high. The hightes population densities of Radopholus spp and Pratylenchus spp were found in Sidiangkat and Bundar Selamat (Dairi) with 34 and 28 juvenile respectively in soil samples and in the root samples were found in Sidiangkat (Dairi) with 107 and 82 juveniles respectively while the lowest population densities of Radopholus spp and Pratylenchus spp were found in Merek Raya (Simalungun) with 12 and 10 juveniles respectively in soil samples and in the root samples were found in Merek Raya with 25 and 20 juvenile respectively.
