Tylenchidae is a family of nematodes. They are an important group of soil dwelling species that frequently contributes as much as 30% to the nematode species richness of soil samples. [2] They diverged relatively early on and many species pose little risk to economically important plant species. [2]
The lack of knowledge about nematode ecology has resulted in unanticipated failures to control pests in the field. For example, parasitic nematodes were found to be completely ineffective against blackflies and mosquitoes due to their inability to swim (Lewis et al.1998).
Root-knot nematodes (Meloidogyne spp.) are one of the three most economically damaging genera of plant-parasitic nematodes on horticultural and field crops.Root-knot nematodes are distributed worldwide, and are obligate parasites of the roots of thousands of plant species, including monocotyledonous and dicotyledonous, herbaceous and woody plants.
Water immersion is another option. Infected plants are immersed in a hot water bath for about 30 minutes, which rids them of nematodes but does not harm the plant. This method has been successful for P. coffeae. [9] Crop rotation can help control the nematode load in the soil because different plants are susceptible to different Pratylenchus ...
The digestive tract is similar to that of free-living nematodes only in the young larvae prior to their parasitic life; in the parasitic stages the oesophagus is disconnected from the mid-intestine, and females lack an anus. The female genital opening is at the midbody, while the male opening is at the tip and visible as one or two spicules.
The nematode is found in all temperate regions around the world, because of the wide host range. For normal nematode activity a moisture film is needed for movement of the nematode. Soil moisture, relative humidity, and related environmental factors directly affect nematode survival. Moisture is needed to the nematode to survive and move.
