The root lesion nematodes Pratylenchus penetrans and P. thornei cause high yield losses in rain-fed wheat fields in Morocco, as well as worldwide. Growing resistant varieties is one of the most effective methods for controlling nematodes. Therefore, a collection of 14 lines of spring wheat and 11 lines of winter wheat (Triticum aestivum and T. durum), provided by CIMMYT, were screened

Root-lesion nematodes of the genus Pratylenchus are among the most important nematode pests that limit production of small-grain cereals. Four Pratylenchus species, viz. P. thornei, P. neglectus, P. penetrans, and P. crenatus, are considered of major economic significance in cereals of which P. thornei and P. neglectus are the most important and widely distributed species

The root-lesion nematode, Pratylenchus thornei, is a serious constraint for agricultural production systems worldwide. Under optimal soil temperature and moisture levels, P. thornei can complete its life cycle in 3-8 weeks (Agrios, 1988), enabling it to increase its population density several times in one cropping cycle. Pratylenchus thornei feeding destroys lateral roots, limiting their ability

Root-knot nematodes ‘Meloidogyne spp’ are the most destructive group of plant parasitic nematodes causeing serious losses in vegetables crops and this damages worsened when crops grown under greenhouses conditions. In this sutdy, the distribution and characterization of root-knot nematode species collected from the Souss region of Morocco where vegetables crops intensively cultivated were determined by

Morphological and molecular diversity among 11 populations of cereal cyst nematodes from different wheat production areas in Morocco was investigated using light microscopy, species-specific primers, complemented by the ITS-rDNA sequences. Morphometrics of cysts and second-stage juveniles (J2s) were generally within the expected ranges for Heterodera avenae; only the isolate from Aïn Jmaa showed morphometrics conforming

Citrus fruits are an important contributor to the Moroccan economy; the industry employs thousands of people and it also serves as a significant source of hard currency. During July 2014, a field survey for the presence of Hop stunt viroid (HSVd) on citrus was conducted in the Gharb region (northwestern Morocco). HSVd is a member of the Pospiviroidae family
