Four new species of Criconematoidea are described from Hoste Island, Chile. Criconema certesi n. sp. is distinguished by the fine, spine-like, cuticular extensions on body annuli; projection of annuli into rows of scales on posterior part of body; single, smooth, labial annulus set off by short collar from second (first body) annulus which is about same diameter as first (labial) annulus. Male ...

abstract in order to identification of plant parasitic nematodes of rosmarinus officinalis rhizospher during 2008-2009, fifty soil and root samples were collected from campus of ferdowsi university. soil and root samples were washed and nematodes were extracted by centrifugal flotation technique. according to de grisse, 1969 the extracted nematodes were fixed and transferred to glycerin. in thi...

Several surveys have been performed in Turkey order to determine a possible presence of Bursaphelenchus xylophilus (Steiner and Buhrer, 1934), Nickle, 1970. As result, several species reported. During study aimed identify potential insect vectors these using the trap tree method western region Turkey, one was isolated from wood chip sample Pinus brutia log located Bergama town city İzmir.

Meloidogyne graminicola is one of the most economically important plant parasitic-nematodes (PPNs). In the present study, we determined the complete mitochondrial (mt) DNA genome sequence of this plant pathogen. Compared with other PPNs genera, this genome (19,589 bp) is only slightly smaller than that of Pratylenchus vulnus (21,656 bp). The nucleotide composition of the whole mtDNA sequence of...

Heterodera raskii n. sp. is described and illustrated from specimens collected from roots of bulb grass, Cyperus bulbosus, in Hyderabad, India. The new species belongs to the 'goettingiana' group and differs from closely related H. cyperi by the elongate ovoid shaped cysts and females, greater fenestral length, width, vulval slit, and absence of egg sac. The stylet knob shape was round in secon...

In the recently published checklist of plant-parasitic nematodes known from Germany (Sturhan 2014) genera and species of the order Tylenchida, which are generally considered as being parasites of higher plants, represent the largest taxonomic group with 212 species. The present paper gives an overview of the remaining trophic groups in Tylenchida: Root tip feeders, myceliophagous species and en...
