The present study on biodiversity of nematode species is necessary in order to assess the biodiversity of parasites in millipede and the species with potential for use as biological control. | Journal of Science – 2015, Vol. 4 (4), 166 – 175 Part D: Natural Sciences, Technology and Environment BIODIVERSITY OF NEMATODE COMPOSITION OF MILLIPEDE-TRIGONIULUS CORALLIUS (DIPLOPODA: TRIGONIULIDAE) Bui Thi Dung1, Pham Van Luc2, Hoang Van Hien1, Nguyen Van Duc3 1 ., Vietnam Academy of Science and Technology, Vietnam Asoc.

The Skrjabin dissection method was used to investigate parasitic nematode in millipedes. The results showed the high prevalence of nematode infection in millipeded (83,33%; 30/36; intensity 1-137 Keywords: nematode per millipede). Ten nematode species were identified (Rhigonema Nematode, millipede, critesi, Rhigonema nesoboli, Cattiena fansipanis, Heth bifidispiculum, Heth Trignoiulus corallines, Tam Dao, vietnamensis, Thelastoma collare, Thelastoma meadsi, Thelastoma medecassa, Cuc Phuong Rhabditis sp., Ichthyocephaloides sumbatus). Among them, two new species (Heth vietnamensis và Cattiena fansipanis) were previously described in Vietnam. The other species were described in other countries but are now first describes in Vietnamese specimens. In Vietnam, millipede Trignoiulus corallinus (Gervais, 1847) is common. However, there is a lack of information about parasites in millipede. Therefore, the present study on biodiversity of nematode species is necessary in order to assess the biodiversity of parasites in millipede and the species with potential for use as biological control. 1. INTRODUCTION Millipede (Diplopoda) plays an important role in the ecosystem. Millipede is involved in the decomposition of plants. They feed on leaves, rotten wood, fungi and plants with soft roots, and green moss (Hopkin & Read, 1992). .
