    Studiul legăturilor trofice și voracitatea prădătorului Amphiareus obscuriceps (Popp.) pe gazde alternative
    (CEP USM, 2024) Iordosopol, Elena; Muntean, Elena; Batco, Mihai; Filimon, Valeriu; Maevschii, Valentina
    The paper presents the results of the study of the natural and laboratory trophic links of the invasive predatory bug species Amphiareus obscuriceps found in the trap belts intended to study the winter reserve of plum crop pests. The predator was offered eggs of different stages of embryonic development of whiteflies Aleyrodes proletella, A. singularis, obtained from the plum plantation; Acanthoscelides obtectus and Galleria mellonella eggs obtained under laboratory conditions. It was determined that the predator can suck in one day on average 40.2 eggs of G. mellonella, 26.1 eggs in the late stage of embryogenesis and 11.7 eggs of one day of A. singularis and 9.3 eggs of A. obtectus.

    Specia nouă de encyrtid parazit al păduchelui pufos (Pseudococcus sp.) la prun în Republica Moldova
    (CEP USM, 2024-10-07) Iordosopol, Elena
    The paper presents the results of the study of the regulatory complex of the mealybugs species of the genus Pseudococcus, which overwinters in the trap belts of the plum crop. It was established that in the adult stage it is parasitized by 5 species of parasites, among them 3 encyrtids, 1 megaspilid and 1 sygniphorid. The highest number of females parasitized by Stemmatosteres bochemicus was recorded in the belts influenced by the apple culture adjacent to the plum. The sex ratio (♀:♂) of the polyembryonic parasite population analyzed was 2:1.
