بررسی و ردیابی آلودگی‌های نماتدی بسترهای کشت قارچ خوراکی ( Agaricus bisoporus (J.E.Lange) Imbach, 1946))

With the increase in population and the possibility of food shortages, changing in the energy sources for human beings, looks necessary. For this, different kinds of edible mushrooms are produced by different ways and discretion of consumers. Among these, the Agaricus bisoporus has first rating in mass production and marketing. Beside big industrial, these mushrooms are grown and cultivated and marketing in smaller quantities by some manufacturers in local and personal chambers. In order to detection and identification of nematode infestation in mushroom culturing chambers, several sampling going on during 2023 in East Azerbaijan province. After extraction and fixation of the nematodes in compost samples by using ordinary methods in nematology and their identification based on available scientific references and literature, it was determined that although some composts are completely free of nematodes, in most of these beds there was bacterial feeding nematodes. The genera Diploscapter Cobb, 1913 (one species- female), Cephaloboides Rahm, 1928 (one species- male/female), Rhabditella two species- male/female), Stomachorhabditis Andrassy, 1970 (one species-female), Panagrolaimus Fuchs, 1930 (one species- male/female) and Mesorhabditis Osche, 1952 (one species- female) were identified. Although the genera and species diversity seems less than estimated by author, very high population of nematode in some samples looks not normal and influences on users is worrying, so it needs that more investigation carried out. In the other hand absence of fungivorous nematodes in all samples despite the availability of a sufficient food source for them in these beds is another matter that needs special attention next researches.
