abstract in order to identify of plant parasitic nematodes of rapeseed in isfahan and fars provinces, 208(96 from esfahan and 112 from fars province) soil and root samples were collected from rapeseed fields during 2005-2007. nematodes were extracted from root and soil , then fixed and transferred to glycerin. the nematodes were mounted on slides and examined by light microscope and identified ...

conclusions rodents play an important role in the transfer of zoonotic parasite diseases, especially those that live near human habitats. control of rodent population in the city should be considered to decrease risk of transmission. results all studied rodents were infected at least by one parasite. the collected parasites included: three species of cestodes, eight species of nematodes, one sp...

A field experiment was conducted to investigate the soil application of two Rhizobacteria, (MTCC and Pf-5) and urea treatments, separately and in combination on free living and plant parasitic nematodes. All the treatments significantly decreased the number of plant-parasitic nematodes with the increasing of plant growth. Both Rhizobacteria and urea were separately effective in suppressing plan...

Nematodes are very common animals and they have repeatedly evolved parasitic lifestyles during their evolutionary history. Recently, the genomes of many nematodes, especially parasitic species, have been determined, potentially giving an insight into the genetic and genomic basis of nematodes' parasitism. But, to achieve this, phylogenetically appropriate comparisons of genomes of free-living a...

introduction the urban population experienced rapid growth in the recent decades, particularly between 1975 and 2000 when it has reached from 1.5 to more than 2 billion people. by turn of the century; half of the world's populations are concentrated in cities. this would severely affect the quality of life in urban areas. accordingly, cities will be faced with significant challenges in inf...

Guidelines are suggested to implement the introduction of beneficial insect-parasitic nematodes into the United States from abroad. These suggestions result from experiences and research with these and other biological control agents and from the current need for procedures to import nematodes. Subjects considered are need to import, foreign exploration, taxonomy, shipment, quarantine facilitie...

in order to identify the plant parasitic nematodes of pulse fields in northern khorasan province, 41 soil and root samples were collected from rhizosphere of pisum sp., phaseoulus sp., lens sp. during 2011 and 2012. the nematodes were extracted by combined sieving and centrifugal-flotation method of jenkins (1969) and transferred to glycerin by using method of de grisse (1969). the permanent sl...
