    INFESTAȚII CU SPECII DE NEMATODE LA FAZANUL COMUN (PHASIANUS COLCHICUS L.) ȘI PREPELIȚE (COTRUNIX COTRUNIX L.) DIN REPUBLICA MOLDOVA
    (CEP USM, 2024) Zamornea, Maria; Erhan, Dumitru; Rusu, Ştefan; Chihai, Oleg; Gliga, Olesea; Botnaru, Nicolai
    Scopul studiului constă în evaluarea nivelului de infestație la păsările de interes cinegetic (fazani, prepelițe) cu nematode. Pe parcursul anilor 2020-2023 de la fazani (Phasianus colchicus L.) și prepelițe (Cotrunix cotrunix L.) au fost recoltate, respectiv, 164 și152 de probe biologice din diverse biotopuri naturale și antropizate ale Republicii Moldova. S-a stabilit infestarea acestora cu 7 specii de nematode (Capillaria caudinflata, Capillaria annulata, Syngamus tracheia, Heterakis isolonche, Ascaridia galli, Heterakis gallinarum,Trichostrongylus tenuis), care aparţin la 5 familii și 5 genuri. La fazani s-a stabilit o prevalență sporită de infestare cu speciile: Ascaridia galli - 44,3%, Heterakis isolonche – 31,2% și Heterakis gallinarum – 16,2%. La prepelițe predomină infestarea cu speciile Ascaridia galli (53,2%) și Heterakis gallinarum (28,7%). Speciile stabilite sunt geohelminţi, comune și la galinaceele domestice.

    NEMATODES ASSOCIATED WITH DECORATIVE PLANTS SPECIES SCHLUMBERGERA TRUNCATA
    (CEP USM, 2022) Gliga, Olesea; Melnic, Maria
    Most decorative plants are susceptible to phytonematodes and this association results in symptoms that compromise the plants commercial value. Were investigated potted epiphytic plants of the species Schlumbergera truncata (Haw.) Moran, 1953, family Cactaceae, with obvious symptoms of disease. As a rsult, at the decorative room plants Schlumbergera truncata with external symptoms of disease, in the rhizosphere area, an outbreak of parasitic nematodes (180-210 individuals/100 cm3 of soil), saprophytic (950-1120 individuals/100 cm3 of soil), enchitraeids (45-50 individuals/100 cm3 of soil) and microorganisms associated with these, were detected. It has been determined that the cause of wilting and drying of room decorative plants species Schlumbergera truncata are root ectoparasitic nematodes from the families Hoplolaimidae and Telotylenchidae, followed by saprophytic species, most of them being from the family Cephalobidae. Remains of putrefied vegetal tissue of plant roots attracted species from the family Enchytraeidae genus. As a result of the associated parasitism, the underground stem and the root of plants are completely deformed, in the process of putrefaction, which led to the total wilting of the plants.
