    (Gazi Entomological Research Society, 2021) Varga, Oleksandr; Bolu, Halil
    The present study was carried out in Diyarbakır Province (N 37°53’36.96”, E 40°16’13.65”, 666 m) in Southeastern Anatolia Region of Turkey in 2018-2020. Prunus cerasifera tree parts infested by the buprestid beetle, Ptosima undecimmaculata, were cut in June 2018 and February 2019 (Figs. 1-2) and Prunus persica infested by buprestids larvae, Ptosima undecimmaculata (Herbst, 1784) and Sphenoptera (Tropeopeltis) tappesi Marseul, 1865, respecitvely were cut and placed in plastic boxes until host and/or their potential parasitoids were reared. Three ichneumonid parasitoids, Dolichomitus kriechbaumeri (Schulz, 1906), Poemenia notata Holmgren, 1859 and Xorides gravenhorstii (Curtis, 1831), were obtained. New host records were found: P. undecimmaculata for D. kriechbaumeri and S. tappesi for X. gravenhorstii. All three parasitoid species were reared from the studied plants for the first time. P. notata is a new record for Turkish fauna.

    New parasitoid records of Arge rosae (Linnaeus, 1758) (Hymenoptera: Argidae) from Diyarbakır province: Tetrastichus hylotomarum (Bouché, 1834) (Hymenoptera: Eulophidae) and Boethus thoracicus (Giraud, 1872) (Hymenoptera: Ichneumonidae)

    Aims: Arge rosae called rose sawfly (Linnaeus, 1758) (Hymenoptera: Argidae) is one of the most important harmful insect of roses around the world. This pest is also causes significant damage on rose plants growing in Diyarbakır province of Türkiye. The aim of this study was to determine the parasitoid(s) of the A. rosae on roses in Diyarbakır province.Methods and Results: The study was conducted between 2017-2018 in established rose garden based on local varieties (pink, red, white, and yellow color) and Isparta variety in Diyarbakır province of Turkey. The cocoons (pupae) of rose sawfly, A. rosae, were collected from rose garden from March to October and was brought to the laboratory for rearing. Rose sawfly cocoons brought to the laboratory were cultured in plastic containers covered with narrow mesh gauze. As a result of this study, two parasitoid species, Tetrastichus hylotomarum (Bouché, 1834) (Hymenoptera: Eulophidae) and Boethus thoracicus (Giraud, 1872) (Hymenoptera: Ichneumonidae) were obtained from reared cocoons of rose sawfly and identified according to morphological and biological characteristics.Conclusions: Two parasitoid species of A. rosae were determined. Tetrastichus hylotomarum (Hymenoptera: Eulophidae), as the parasitiod of A. rosae, was recorded for the first time in Türkiye with this study. Detailed studies are required on the distribution areas, parasitization rates and activities of these two new natural enemies in future studies. In particular, studies are focused on biological and biotechnical methods which do not leave residues on nature.Significance and Impact of the Study: A. rosae is an important pest that causes economic damage to rose plants. It is thought that A. rosae determined in this study may have the potential to be used as a biological control agent for two parasitoid species.
