The potato rot nematode, Ditylenchus destructor, is a very destructive nematode pest on many agriculturally important crops worldwide, but the molecular characterization of its parasitism of plant has been limited. The effectors involved in nematode parasitism of plant for several sedentary endo-parasitic nematodes such as Heterodera glycines, Globodera rostochiensis and Meloidogyne incognita h...

In an outside pot experiment, dry pig manure processed on pine sawdust litter and fermented for seven days by house fly larvae (fermented manure), and pine sawdust applied alone, and in combination with a spring application of inorganic nitrogen fertilizer were used to determine their effects on plant parasitic and free-living soil nematodes on sugar beets (cv. Antek). Non amended soil was used...

Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals occur worldwide in all environments. Most species are beneficial to agriculture. They make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. Pla...

Over the last decade the need for new strategies and compounds to control parasitic helminths has become increasingly urgent. The neuromuscular systems of these worms have been espoused as potential sources of target molecules for new drugs which may address this need. One facet of helminth neuromuscular biology which has garnered considerable research interest is that of neuropeptidergic neuro...

abstract in order to identify plant parasitic nematodes of potato fields, 55 soil samples and a few tuber samples were collected from khorasan razavi province during 2005-2006 .soil samples were washed and nematodes were extracted by centrifugal flotation technique. the extracted nematodes were fixed and transferred to glycerin. baermann funnel method was used for extracting nematodes from tube...

in order to investigate the biodiversity of plant parasitic nematodes of vegetable fields in mashhad area, 51 soil and root samples were collected during 2010-2011. nematodes were extracted by centrifugal flotation technique and transferred to glycerin according to the modified de grisse method (1969). the permanent slides were prepared from the extracted nematodes. the nematodes were identifie...

Cucumber plants play an important role in economical field in Egypt. But they are infected by plant parasitic nematodes that leading to losses cucumber yield. This study attempted to construct more efficient bacterial strains may be able to controlling nematodes, as well as, maintenance the soil fertility using molecular biology method via induced protoplast fusion between different strains of ...

A drip irrigation delivery system was used to infest field sites with the plant-parasitic root-knot nematodes, Meloidogyne incognita. Juvenile or egg inocula passed through the system without blockage of emitters or harm to the nematodes. Field sites so infested were available for experimentation. Delivery of approximately 5 x 10 to 10 juveniles or 10 to 3 x 10 eggs per emitter through the drip...
