Although a 35% population increase is projected by 2050. Significant improvements are consequently necessary in terms of resource use efficiency. In moving crop yields towards an efficiency frontier, optimal pest and disease management will be essential, especially as the proportional production of some commodities steadily shifts. With this in mind, it is essential that the full spectrums of crop production limitations are considered appropriately, including the often overlooked nematode constraints about half of all nematode species are marine nematodes, 25% are free-living, soil inhabiting nematodes, I5% are animal and human parasites and l0% are plant parasites. Today, even with modern technology, 5-l0% of crop production is lost due to nematodes in developed countries. So, the aim of this work was to review some agricultural nematodes genera, species they contain and their management methods. In this review work the species, feeding habit, morphology, host and symptoms they show on the effected plant and management of eleven nematode genera was reviewed. -

November 2002 Division of Plant Industry The Mediterranean Cereal Cyst Nematode, Heterodera latipons: a Menace to Cool Season Cereals of the United States1 N. Greco2, N. Vovlas2, A. Troccoli2 and R.N. Inserra3 INTRODUCTION: Cool season cereals, such as hard and bread wheat, oats and barley, are among the major staple crops of economic importance worldwide. These monocots are parasitized by many pathogens and pests including plant parasitic nematodes. Among nematodes, cyst-forming nematodes (Heterodera spp.) are considered to be very damaging because of crop losses they induce and their worldwide distribution. The most economically important cereal cyst nematode species damaging winter cereals are: Heterodera avenae Wollenweber, which occurs in the United States and is the most widespread and damaging on a world basis; H. filipjevi (Madzhidov) Stelter, found in Europe and Mediterranean areas and most often confused with H. avenae; and H. hordecalis Andersson, which seems to be confined to central and north European countries. In the 1950s and early 1960s, a cyst nematode was detected in the Mediterranean region (Israel and Libya) on the roots of stunted wheat plants (Fig. 1 A,B). It was described as a new species and named H. latipons based on morphological characteristics of the Israel population (Franklin 1969). Subsequently, damage by H. latipons was reported on cereals in other Mediterranean countries (Fig. 1). MORPHOLOGICAL CHARACTERISTICS AND DIAGNOSIS: Heterodera latipons cysts are typically ovoid to lemon-shaped as those of H. avenae. They belong to the H. avenae group be- cause they have short vulva slits (< 16 µm) (Figs. -

DNA-based diagnostic methods have already gained acceptance in applications ranging from quarantine determinations to assessments of biodiversity. Researchers are currently in an information-gathering mode, with intensive efforts applied to accu- mulating nucleotide sequence of 18S and 28S ribosomal genes, internally transcribed spacer regions, and mitochondrial genes. Important linkages with collateral data such as digitized images, video clips and specimen voucher web pages are being established on GenBank and NemATOL, the nematode-specific Tree of Life database. -

This group of nematodes is considered the most economically damaging pathogens of wheat and barley in Iran. In the present study, a series experiments were conducted during 2007-2010 to determine the distribution and population density of cereal cyst nematodes and to examine the biology of Heterodera latipons in the winter wheat cv. Sardari in a microplot under rain-fed conditions over two successive years in Markazi province in central Iran. Results of field survey showed that 40% of the fields were infested with at least one species of either Heterodera filipjevi or H. latipons. H. filipjevi was most prevalent in Farmahin, Tafresh and Khomein, with H. latipons being found in Khomein and Zarandieh regions. Female nematodes were also observed in Bromus tectarum, Hordeum disticum and Secale cereale, which are new host records for H. filipjevi. Also, H. filipjevi and H. latipons were found in combination with root and crown rot fungi, Bipolaris sorokiniana, Fusarium culmorum, F. -
