    Hibernating arthropods’ complex in the plum tree orchard under the influence of green manures and nectariferous plants [Articol]
    (Editura USM, 2025) Iordosopol, Elena; Batco, Mihail; Eliseev Serghei; Fron, Arcadie; Filimon, Valeriu; Iordosopol, Valentina; Fron, Argentina; Muntean, Elena
    The work represents the highlighting of the arthropod complex, which populates and hibernates in the cardboard trap belts of the plum orchard influenced by green manures and nectariferous crops. This complex is composed of phytophagous, saprophagous, predators and parasites. In the trapping belts, polyphagous species of five families of spiders dominated, which constituted an average of 33.5% of the total individuals highlighted, and coccinellids (seven species) - an average of 6.5%. The parasitoid Scambus inanis achieved a degree of parasitism of moth larvae in average 29.4%. The highest percentage was recorded in the standard and experimental variants (46.0% and 35.3%) respectively.

    Evaluation of Zeuzera pyrina infestation in walnut orchards and proposal of an alternative ecological control method [Articol]
    (Editura USM, 2025) Fron, Arcadie; Batco, Mihail
    The study assessed the impact of the xylophagous pest Zeuzera pyrina on walnut orchards in the central region of the Republic of Moldova, providing a detailed phenological and ecological profile. Monitoring of adult populations revealed an active flight period between May and August, correlated with temperatures above 25°C. Field data indicated an average infestation rate of 24.4% among the analyzed trees, with 58.1% of their branches being affected. The larvae produce galleries up to 50 cm in length, causing significant structural damage. An unusually high trophic plasticity was observed, with larvae also feeding on foliage under limiting conditions. Given the difficulty of applying contact insecticides, the study proposes an innovative ecological control method: detection of larvae using acoustic sensors and injection of a biologically active substance. This approach offers ecological, selective advantages and is compatible with modern technologies, representing a viable solution for sustainable pest management and the preservation of walnut orchard health.

    Modul de atac al Zeuzera pyrina și impactul său devastator asupra pomilor din livezi
    (CEP USM, 2024) Fron, Arcadie
    The walnut orchard industry in the Republic of Moldova faces significant threats from the pest Zeuzera pyrina, which can drastically reduce crop yield and quality. This study investigates the monitoring and management of this pest in a 1.5 hectare walnut orchard, analyzing its impact on tree health and developing effective control methods. Population monitoring was conducted using pheromone traps and visual inspections, revealing significant fluctuations influenced by weather conditions. Z. pyrina poses a considerable risk by damaging the tree structure. The study emphasizes the necessity of integrated pest management, combining biological and chemical methods to mitigate infestations. Future research should focus on developing localized control strategies and fostering collaboration between researchers, farmers, and authorities to ensure the sustainability and productivity of walnut crops.

    The study of CIS-jasmone additives for parasitoid hymenoptera attraction
    (CEP USM, 2024) Eliseev, Serghei; Fron, Arcadie
    The evaluation of common activity of phenylethanol and methyl salicylate with cis-Jasmone additives was tested and discussed. Phenylethanol paired with cis-Jasmone proved to attract Trichogrammatidae specimens.

    ZEUZERA PYRINA: THE THREATENING LEOPARD MOTH DAMAGING FRUIT TREES
    (CEP USM, 2023) Fron, Arcadie
    This article provides a comprehensive overview of Z. pyrina, including its life cycle, behavior, impact on fruit tree health, and management strategies. Through a thorough review of credible sources and scientific research, this article highlights the destructive nature of Z. pyrina larvae, which burrow into the wood, disrupting the flow of water and nutrients and weakening the tree's structure. The article emphasizes the importance of early detection, cultural practices, biological control, and judicious use of chemicals in managing Z. pyrina infestations. By presenting a concise summary of relevant information, this article aims to enhance understanding and support effective strategies for combating the detrimental effects of Z. pyrina on fruit tree cultivation.

    UTILIZAREA NECTARIFERILOR ȘI ANALIZA COMPLEXULUI LOR FAUNISTIC LA PRUN (I).
    (CEP USM, 2023-02-13) Iordosopol, Elena; Batco, Mihail; Fron, Arcadie
    The work renders the synecological analysis of the faunistic complex accumulated in the Lobullaria maritima L. used in the late plum plantation and compared to Gypsofilla paniculata L. Nectariferous culture Lobullaria maritima accumulated 27% of predators, 23% of parasites, 3 times more and 50% of phytophagious of 1,3 less.
