A study was undertaken to isolate and identify different genera of plant parasitic nematodes from soil and plant samples during July to October 2007 in the Laboratory of Plant Pathology at Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh. Altogether 10 (Ten) nematodes belonging to 10 genera were isolated and identified from various soil and plant samples. For identification of plant parasitic nematodes, stylet and other anatomical structures such as Dorsal esophageal Gland Orifice (DGO), Esophageal lumen, Median bulb, Basal bulb, Intestine, Reproductive structures (vagina and its position, specula ) Tail types etc. were used as main criteria. Among 10 (ten) different identified genera of nematodes (Criconemoids sp., Hemicriconemoides sp., Tylenchus sp., Ditylenchus sp., Tylenchorhynchus sp., Hoplolaimus sp., Helicotylenchus sp., Pratylenchus sp., Meloidogyne sp., Radinaphelenchus sp.) maximum nematodes were under the family of Tylenchidae. The abundance numbers of plant parasitic nematodes were found as the Ditylenchus sp.(Ufra nematode) and Meloidogyne sp.(Root knot nematode) which were the serious plant pathogens causing ufra in rice and root knot in different crops respectively, so far recorded in Bangladesh.

Isolated Species

Plant-parasitic nematodes are of considerable importance worldwide and their devastating effects on crops have major economic and social impacts. They depend on plants and feed on all parts of the plant including roots, stems, leaves, flowers and seeds. The majority of species of plant-parasitic nematodes live on or around plant roots. Nematode damage of the plant’s root system also provides an opportunity for other plant pathogens to invade the root and thus further weakens the plant. A study was carried out to isolate and identify different genera of plant parasitic nematodes from the rhizospheres of pear plants in one of the major pear producing area of Nepal, Chhaimale VDC of Kathmandu district. Altogether seven species of root nematodes were isolated from soil samples collected: Tylenchorhynchus sp., Longidorus sp., Helicotylenchus sp., Hoplolaimus sp., Aphelenchus sp., Mononchus sp. and Diplogaster sp. Among isolated species of nematodes Tylenchorhynchus sp., Longidorus sp., Helicotylenchus sp., and Hoplolaimus sp. are parasitic, Aphelenchus sp. is mycophagic and Mononchus sp. and Diplogaster sp. are predatory in nature. Number of nematodes were not significantly different in different season and at different locations.

Abstract Plant parasitic nematodes are among the most destructive plant pathogens, causing an estimated US$78 billion yield losses globally. Although approximately 3000 species of plant parasitic nematodes have been described, most of the damage is caused by a small group of root-infecting sedentary endoparasitic nematodes that include root-knot nematodes (Meloidogyne spp.) and cyst nematodes (Heterodera spp.). Given that previous literature amply reviews the breadth of biotechnological methods for the control of plant parasitic nematodes, this chapter will briefly touch on long-standing biotechnological methods but focus on recent progress in, and long-term promise of, the use of CRISPR technology for introducing targeted modifications into host genomes with the goal of enhancing resistance against plant parasitic nematodes. It is predicted that expanding reverse genetic approaches beyond RNA interference, using low-cost, technically simple and efficient transformation (transient or stable) will be the single most important advance in the field in some years.
