Abstract: | Introduction. Potato (Solanum tuberosum L.) is susceptible to infestation with an associated complex of different species of parasitic and saprophytic nematodes, bacteria, fungi,
and arthropods, which diminish the quality of the product.
Material and methods. 10 varieties of potatoes were investigated (Agata, Albastriu-mov,
Bella rosa, Concorde, Desiree, Irga, Iagodca, Roko, Romano, Sprinter), cultivated on the territory of the Republic of Moldova. The extraction of nematodes and mites was performed
using the Baermann funnels, modified by Nesterov.
Results. Multiannual researches on the degree of potato infestation have shown that tubers
are preferred by various arthropods (Acaridae), Agriothes spp. (Elateridae), Gryllotalpa
gryllotalpa, (Grillotalpidae) and Sciaridae spp. (Sciaridae), which form different interactions with the parasitic nematodes of tubers (Ditylenchus destructor, D. dipsaci).
Conclusions. Solanum tuberosum infested by parasitic nematodes D. destructor in association with saprophytic nematodes and dry rot are colonized by nematophagous (mites – 80%)
and phytophagous arthropods (wireworms – 40%; mole cricket – 50%; flies – 40%). Among
the researched arthropods, Rhizoglyphus echinopus were more frequently found, which together with other species actively consume the primary and secondary parasitic nematodes,
their mortality constituting up to 90%. In the traumatized by some arthropods potatoes,
with the soil, secondary parasitic nematodes, also penetrate, carrying bacterial and fungal
infections, subsequently stimulating the total rot of potato tubers. Introducere. Cartoful (Solanum tuberosum L) este susceptibil la infestare cu un complex
asociat de diferite specii de nematode parazite, saprofite, bacterii, ciuperci și artropode, ceea
ce îi diminuează din calitatea lui ca produs.
Material și metode. Au fost cercetate 10 soiuri de cartofi (Agata, Albăstriu-mov, Bella rosa,
Concorde, Desiree, Irga, Iagodka, Rocko, Romano, Sprinter) cultivate în Republica Moldova.
Extragerea nematodelor și a acarienilor s-a efectuat cu utilizarea pâlniilor Baermann, modificate de Nesterov.
Rezultate. Cercetările multianuale, privind gradul de infestare a cartofilor, au demonstrat
că tuberculii sunt preferați de diferite artropode: Agriotes spp. (Elateridae), Gryllotalpa
gryllotalpa, (Grillotalpidae) și Sciaridae spp. (Sciaridae), care stabilesc interrelații diverse
cu nematodele parazite (Ditylenchus destructor, D. dipsaci) ale culturii.
Concluzii. Solanum tuberosum, infestat de nematodul parazit Ditylenchus destructor, în
asociere cu nematodele saprofite și cu putregaiul uscat, este colonizat de artropodele nematofage (acarieni – 80%) și fitofage (viermii-sârmă – 40%; coropișnițe – 50%; musculițe –
40%). Printre artropodele cercetate, mai frecvent a fost atestat Rhizoglyphus echinopus(Fumouze & Robin, 1868), care, împreună cu alte specii, consumă activ nematodele parazite
primare și pe cele secundare, mortalitatea acestora constituind până la 90%. În cartofii
traumați de unele artropode, odată cu solul, pătrund și nematodele parazite secundare,
purtătoare ale infecțiilor bacteriene și fungice, stimulând ulterior putrefacția totală a tuberculilor. |
