Представлена информация об ущербе картофелеводству от дитиленхоза в последние годы. Описаны симптомы поражения картофеля клубневой картофельной нематодой, биология возбудителя, его устойчивость к факторам внешней среды. Детально представлены эпифитотиология дитиленхоза картофеля (вертикальный, хронологический, горизонтальный механизмы передачи и сохранения возбудителя), способы его диагностики, меры защиты в фермерских, крестьянских и личных хозяйствах.Information on the damage to potatoes from Ditylenchus destructor in recent years is presented. The symptoms of the potato lesion by Ditylenchus destructor, the biology of the pathogen, its resistance to environmental factors are described. Epiphytotiology (vertical, chronological, horizontal mechanisms for the transfer and preservation of the causative agent), methods of its diagnosis, protective measures at peasant and private farms are given in details.

Plant Parasitic

Plant-parasitic nematodes were found in 4 of the 12 clades of phylum Nematoda. These nematodes in different clades may have originated independently from their free-living fungivorous ancestors. However, the exact evolutionary process of these parasites is unclear. Here, we sequenced the genome sequence of a migratory plant nematode, Ditylenchus destructor . We performed comparative genomics among the free-living nematode, Caenorhabditis elegans and all the plant nematodes with genome sequences available. We found that, compared with C. elegans , the core developmental control processes underwent heavy reduction, though most signal transduction pathways were conserved. We also found D. destructor contained more homologies of the key genes in the above processes than the other plant nematodes. We suggest that Ditylenchus spp. may be an intermediate evolutionary history stage from free-living nematodes that feed on fungi to obligate plant-parasitic nematodes. Based on the facts that D. destructor can feed on fungi and has a relatively short life cycle, and that it has similar features to both C. elegans and sedentary plant-parasitic nematodes from clade 12, we propose it as a new model to study the biology, biocontrol of plant nematodes and the interaction between nematodes and plants.

Correct Size

A technique was developed for the identification of Ditylenchus destructor nematode belonging to the Ditylenchus genus, based on the use of different primers for polymerase chain reaction (PCR). Two universal ribosomal primers were amplified to the internal transcribed spacer region ITS-rDNA. The sequencing of PCR products confirmed the polymorphism between species. The primers were sensitive to generate a particular band of the correct size (300bp) from the DNA template of a single, separate D. destructor stage of development. Screening populations of D. destructor from Iran and the Russian Federation have tested the reliability of the primers, and the expected size of the band was produced for all test populations. Ditylenchus destructor closely related species have also been tested and no specific band was amplified. Such results showed that the primers currently developed are useful for quantifying the D. destructo r density in potato tuber.

Ditylenchus Destructor

Abstract The potato tuber nematode (PTN), Ditylenchus destructor, is ranked second only to the potato cyst nematode, Globodera rostochiensis, in importance in Russia. D. destructor is distributed throughout the former Soviet Union, now the Russian Federation, but has had no significant economic impact in the past. This historically low impact was due to the fact that around 80-90% of potato tuber yield had been produced on small private gardens or fields of approximately 600 square metres. This chapter discusses the economic importance, host range, distribution, biology and life cycle, symptoms of damage, interactions with other nematodes and pathogens, recommended integrated nematode management and management optimization of D. destructor. Future research requirements are also mentioned.
