Christie (1932) (datasheet\6381#EB80736F-8A80-4666-900F-AAEA17123CBA) transferred it to Aphelenchoides Fischer, 1894. The species has been assigned to the family Aphelenchidae Fuchs, 1937 and later, more appropriately, to Aphelenchoididae Skarbilovich, 1947. Aphelenchoides olesistus Ritzema Bos, 1893 (Steiner, 1932) and Aphelenchoides pseudolesistus Goodey, 1928 (Goodey, 1933 (datasheet\6381#56C56AB2-A7B2-4D3E-88DA-4C009D8C00A5)) are junior synonyms of Aphelenchoides fragariae. The type host and locality of A. fragariae are strawberry plants, Kent, UK. The neotype proposed and described by Allen (1952) (datasheet\6381#88670F52-FE19-440D-B5BD-96D867C05F20) came from strawberry in Escalon, California, USA. / Description Top of page Morphology of A. fragariae is given by Allen (1952) (datasheet\6381#88670F52-FE19-440D-B5BD-96D867C05F20), Siddiqi (1975) (datasheet\6381#2BC3A4AB-F551-47B3-B5F7-DC33241098F9), Franklin and Southey (1978) (datasheet\6381#CCE6ED9A-ABDC- 4521-ACA4-629A0054CA80), Hunt (1993) (datasheet\6381#3E74D2F1-1A50-4E8A-938D-E3C0CAD0EE52). Measurements (after Allen, 1952 (datasheet\6381#88670F52-FE19-440D-B5BD-96D867C05F20)). Females: Length = 0.45-0.80 mm; a = 45-60 µm; b = 8-15 µm; c = 12-20 µm; V = 64-71%. Males: Length = 0.48-65 mm; a = 46-63 µm; b = 9-11 µm; c = 16-19 µm; T = 44-61%. Body very slender (a=45-63 µm). Cuticle marked by fine transverse striae about 0.9 µm apart; lateral field with 2 incisures appearing as a plain narrow band. Cephalic region, smooth, anteriorly flattened with straight to curved side margins, almost continuous with body contour. Stylet slender, about 10-11 µm long, with minute but distinct basal knobs and sharply pointed tip. Median oesophageal bulb prominent, somewhat oval, filling body cavity, with large cuticular valvular apparatus in centre. Oesophageal glands forming a lobe extending over intestine dorsally. Nerve ring about one body width behind median bulb. Excretory pore level with or close behind nerve ring. Tail elongate-conoid, bearing a terminal peg which is simple, spike-like. Female: Body when relaxed becomes straight to slightly arcuate ventrally. Vulva a transverse slit, at 64-71% of body. Spermatheca elongate-oval. Postvulval uterine sac more than half the vulva-anus distance, often containing sperm. Ovary single, with oocytes in a single row. Male: Abundant. Posterior region of body curved through 45-90 degrees. Testis single, outstretched; sperm large-sized, rounded, in a row. Spicules large and prominent, smoothly curved, rosethorn-shaped, with moderately developed dorsal and ventral processes (apex and rostrum) at proximal end; dorsal limb 14-17 µm long. Juveniles: Four juvenile stages, resembling female in general morphology but lacking genital structures. / Distribution Table Top of page The distribution in this summary table is based on all the information available.

  • Race Genesis in Ditylenchus Dipsaci 1) by D. R. Viglierchio
    RACE GENESIS IN DITYLENCHUS DIPSACI 1) BY D. R. VIGLIERCHIO Department of Nematology, University of California, Davis A garlic isolate of Ditylenchus dipsaci has been found to be polyphagous.Under aseptic conditions this isolate has reproduced on a wide range of plant host tissues many of which are the key hosts reported for the biological races of the stem and bulb nematode. In addition the garlic isolate reproduced on two of nineteen fungus cultures tested. It is clear from the literature reports of many workers that different populations of D. dipsaci can vary in host ranges from very narrow to very broad. It is suggested, as a working hypothesis, that the nominal species, Ditylenchus dipsaci, gene pool be considered as "wild type" polyphagous with race deviations as part of the gene continuum in the fashion illustrated by the schematic representation. The stem and bulb nematode, Ditylenchu.r dipsaci, has been recognized for just over a century. It is perhaps the best known of all plant-parasitic nematodes for complexity in racial characterization. Though restricted essentially to the temperate zones of the world, representatives of the species have been found in hot desert soils, irrigated warm lands, cool most areas, and cold high mountain valleys wherever a host plant is able to grow. The nematode's cryptobiotic state enables it to survive sub-zero winter temperatures, summer soil temperatures of 55°C, or decades of desiccation. It is one of the more cosmopolitan of plant-parasitic nema- todes. It has been reported on nearly 50 botanical families including bryophytes and monocotyledonous and dicotyledonous plants (Filipjev & Schuurmans Stek- hoven, 1941).

  • PCR-RFLP and Sequencing Analysis of Ribosomal DNA of Bursaphelenchus Nematodes Related to Pine Wilt Disease(L)
    Fundam. appl. Nemalol., 1998,21 (6), 655-666 PCR-RFLP and sequencing analysis of ribosomal DNA of Bursaphelenchus nematodes related to pine wilt disease(l) Hideaki IvVAHORI, Kaku TSUDA, Natsumi KANZAKl, Katsura IZUI and Kazuyoshi FUTAI Cmduate School ofAgriculture, Kyoto University, Sakyo-ku, Kyoto 606-8502, Japan. Accepted for publication 23 December 1997. Summary -A polymerase chain reaction - restriction fragment polymorphism (PCR-RFLP) analysis was used for the discri­ mination of isolates of Bursaphelenchus nematode. The isolares of B. xylophilus examined originared from Japan, the United Stares, China, and Canada and the B. mucronatus isolates from Japan, China, and France. Ribosomal DNA containing the 5.8S gene, the internai transcribed spacer region 1 and 2, and partial regions of 18S and 28S gene were amplified by PCR. Digestion of the amplified products of each nematode isolate with twelve restriction endonucleases and examination of resulting RFLP data by cluster analysis revealed a significant gap between B. xylophllus and B. mucronatus. Among the B. xylophilus isolares examined, Japanese pathogenic, Chinese and US isolates were ail identical, whereas Japanese non-pathogenic isolares were slightly distinct and Canadian isolates formed a separate cluster. Among the B. mucronalUS isolates, two Japanese isolares were very similar to each other and another Japanèse and one Chinese isolare were identical to each other. The DNA sequence data revealed 98 differences (nucleotide substitutions or gaps) in 884 bp investigated between B. xylophilus isolare and B. mucronmus isolate; DNA sequence data of Aphelenchus avenae and Aphelenchoides fragariae differed not only from those of Bursaphelenchus nematodes, but also from each other.

  • Impact of Trade on Distribution of Potato Rot Nematode (Ditylenchus Destructor) and Other Plant Nematodes
    Agronomy Research 10 (1–2), 319–328, 2012 Impact of trade on distribution of potato rot nematode (Ditylenchus destructor) and other plant nematodes E. Kruus Institute of Agricultural and Environmental Sciences, Estonian University of Life Sciences, Kreutzwaldi 1, 51014 Tartu, Estonia; e-mail: [email protected] Abstract. Scarce status reports give but little substance for convincing conclusions about the gravity of the current problem with the potato rot nematode (Ditylenchus destructor Thorne 1945). This paper reviews the international experience and presents the survey of the most recent plant nematode interception reports by member states of the European and Mediterranean Plant Protection Organization. Factors influencing the distribution and invasiveness of the species are discussed. The majority of the nematode infestations were identified in consignments of bonsai or aquarium plants, originating predominantly from Asia via Western European countries. Potatoes were the most frequent nematode pathways as detected by Northern, Eastern and Southern Europe. D. destructor has been among the ten best recognised phytonematodes in the international plant trade, even though it was present only in about 3% of the nematode-related interceptions of potato lots. Seed potato has been found contaminated with Potato Cyst Nematodes on several occasions, whereas latent potato rot nematode infestation in ware potato or ornamental plants may easily be overlooked. Special research programs, including the comparative population genetic analyses are necessary to establish the natural and introduced distribution of D. destructor and substantiate creating pest free areas. Key words: plant health, invasion, phytosanitary measures INTRODUCTION Potato rot nematode Ditylenchus destructor Thorne 1945has resulted in serious economic consequences in Eastern European potato production.
