    CERCETĂRI HELMINTOLOGICE CU IMPACT INVAZIV STABILITE LA CULTURA DE MAZĂRE (PISUM SATIVUM L.) ÎN CONDIȚIILE DE MEDIU ALE REPUBLICII MOLDOVA

    One important factor in increasing the productivity and quality of peas (Pisum sativum L.) grown in the conditions of the Republic of Moldova is the phytosanitary control of parasitic helminthological fauna. The investigations were carried out in four administrative districts of the central areas, covering twelve pea sectors from various regions specialized in the cultivation of fabaceous plants. As a result of the helminthological protection investigations in peas, the parasitic degree was established for the first time, with comparative indices of number density ranging from 15 to 250 individuals per 100g of soil, and an abundance of 7–25% in spring. The frequency indices of the attack degree and extensiveness of helminthological affections showed more advanced values (5–30%) in the summer, varying across plantation areas. The structure of the nematode parasite complexes was determined, consisting of eight genera, including six families and one order, classified according to their trophic specialization. There was a predominance of endoparasite and semiendoparasite species from the Heteroderidae, Tylenchidae, and Hoplolaimidae families.

    EFFECT OF PLANT PARASITIC NEMATODES ON OLIVE PLANTLETS OF XYLELLA-RESISTANT CULTIVAR FAVOLOSA

    Two experiments were carried out to verify the susceptibility of olive plantlets of the Xylella fastidiosa - resistant cultivar Favolosa to the root-knot nematode Meloidogyne javanica and the root lesion nematode Pratylenchus vulnus. In the first experiment the relationship between the nematode population density and the olive plants growth was assessed. Plant growth parameters, main shoot length and diameter and number of nodes, were analysed by the SeinFit program in order to calculate the tolerance limit (T) to the nematode attack and the minimum relative per cent growth (m) of the plants. In the second trial, the reaction of olive plantlets to P. vulnus was assessed by measuring the growth parameters after P. vulnus inoculations (200 juveniles/plant). The susceptibility to the nematode was evaluated on the base of the reproduction factor r = Pf/Pi according to r value: NH (non host) = Pf300 nematodes/plant. For each trial ten replications were considered. Both trials indicated a susceptibility of the cv. Favolosa to both phytoparasitic nematodes despite of its resistance to Xylella fastidiosa.

    A REVIEW OF THE MAJOR PEST INSECTS OF TOMATO CROPS IN THE REPUBLIC OF MOLDOVA
    (Academia de Ştiinţe a Moldovei, 2019) Moldovan, Anna; Munteanu-Molotievskiy, Natalia; Toderash, Ion; Iurcu-Străistaru, Elena
    Prezenta lucrare este dedicată inventarierii entomologice a insectelor dăunătoare evidențiate în cultura de tomate pe sectoare de teren protejat şi câmp deschis din Republica Moldova. Este prezentată lista celor mai semnificative specii de insecte dăunătoare, asociate cu plantele de tomate în diverse perioade de vegetație. De asemenea, sunt reflectate informații sintetizate în baza surselor bibliografice, ce țin de răspândirea în plan mondial, aspecte ale gradului de dăunare și infestare, plantele-gazdă și specializarea trofică. Rezultatela cercetărilor sunt prioritare în vederea elaborării și ajustării unor procedee eficiente de protecție aplicate în sistemul de management sustenabil al dăunătorilor la tomate.
