The effectiveness in trapping the chestnut gall wasp by using sticky attractant traps combined with attractants during its active flying period was determined. The combination of yellow sticky traps with a mixture of 90% beer and 10% granulated sugar can have a significant impact on the populations of the pest. This method offers a high success rate in chestnut production regions due to reasons such as their success in attracting chestnut gall wasp adults, the fact that they do not have any negative effects on biological control studies carried out using Torymus sinensis, and offers an effective solution for chestnut gall wasp control without negative effects on nature and the environment.Öğe Effect of climate change on potential distribution areas of the invasive oak lace bug [Corythucha arcuata (Say, 1832)] (Heteroptera: Tingidae) on oak forests of Turkiye(Springer Heidelberg, 2025) Sarikaya, Oguzhan; Gencal, Tutku; Uzun, Almira; Sarikaya, Ayse Gul; Yildiz, YafesThis study aimed to model the current and future (2041-2060 and 2081-2100) potential distribution areas of the oak lace bug Corythucha arcuata (Say, 1832) with the HadGEM3-GC31-LL model according to the SSP2 and SSP5 emission scenarios. Pearson correlation analysis was performed to select the bioclimatic data to be included in the model. The following seven climatic variables were used: annual mean temperature, maximum temperature in the warmest month, mean temperature during the wettest quarter, mean temperature during the driest quarter, annual precipitation, precipitation seasonality and precipitation during the driest quarter. The current potential distribution area model for C. arcuata established with the Maxent algorithm shows that this species is concentrated in the Marmara and Black Sea regions. According to the HadGEM3-GC31-LL climate change model and the SSP2-45 scenario, during the 2041-2060 (similar to 2050) period, there will be a general narrowing in the species distribution area, with suitable and highly suitable areas concentrated in some regions of Marmara, along the Black Sea coastline, and in the interior. Therefore, state forestry authorities should implement precautions for this pest in oak stands in northern Turkiye.Öğe Larvicidal Effect of Some Essential Oils Against Larvae of the European Pine Sawfly [Neodiprion Sertifer (Geoff.)](Int Journal Lifescience & Pharma Research, 2022) Sarikaya, Oguzhan; Sarikaya, Ayse Gul; Sen, Ismail; Gencal, TutkuMany of the species that cause damage to pine trees by feeding on needle leaves, and trees without leaves may be vulnerable to secondary pests as well as increment loss. One of the important leaf pests that damage Turkish red pine (Pinus brutia) and the Anatolian Black pine (Pinus nigra A.Rich) in Turkey is the pine sawfly Neodiprion sertifer (Geoff.). Only mechanical and chemical control methods are carried out with this pest. Due to the negative effects of chemical control methods on the ecosystem and nature, alternative methods have come to the fore front in recent years. One of them is the use of essential oils against harmful insects. The aim of the study is determine to larvicidal effects of some essential oils against larvae of N. sertifer. To achieve of this aim our objective is applied three different dosages (0.1%, 0.5% and 1.0%) of essential oils obtained from Eucalyptus camaldulensis, Melissa officinalis and Origanum onites plants to the 4th and 5th instar larvae of pine sawfly. Trials were carried out in the laboratory under controlled conditions ( 25 +/- 5 degrees C temperature and 65 +/- 5% proportional humidity). Dead larvae in each box were counted 12, 24, 36 and 48 hours after application. According to the application dosages, the highest deaths of N. sertifer larvae occurred at 1% doses of all three essential oils. It was observed that the larval mortality rates increased as the dosages increased. As a result, essential oils of all three plant species were found to be hopeful in the controlling of N. sertifer, of which essential oil of O.onites was found more effective on the 4th and 5th instar larvae than the essential oils of the other two plant species. They have shown that essential oils can be a potential alternative to synthetic insecticides in the control of pine sawfly.Öğe Notes on bark beetle fauna in forests of Bursa Province (Marmara Region) of Turkey, with new records for Marmara Region(Univ Oradea Publ House, 2023) Gencal, Tutku; Sarikaya, Oguzhan[Abstract Not Available]Öğe Predatory species of Scolytinae in Bursa province of Turkey(Al-Farabi Kazakh Natl Univ, 2023) Gencal, Tutku; Sarikaya, OguzhanScolytinae, a large group of Coleoptera, are a vital community that causes forest damage. Species such as Pityokteines curvidens (Germar), Orthotomicus erosus (Wollaston), Tomicus destruens (Wollaston), Tomicus minor (Hartig) and Ips sexdentatus (Boerner) are particularly prevalent in the region. In recent years, the prevalence of bark beetle species causing tree damage in the Bursa province has increased. The purpose of this study was to determine the predator species of bark beetles responsible for causing damage in the forest areas of the Bursa province. Specimens were collected from 8 sites in the study area and identified as belonging to 25 species in 2 orders and 12 families. In study found that species such as Synuchus vivalis (Illiger), Opilo taeniatus (Klug), Trichodes apiarius (Linnaeus), Anthrenus scrophulariae (Linnaeus), Trogoderma angustum (Solier), Trogoderma glabrum (Herbst), Ampedus cinnaberinus (Eschscholtz), Cylister angustatus (Hoffmann), Cylister filiformis (Erichson), Rhizophagus depressus (Fabricius), Rhizophagus dispar (Paykull), Ipidia binotata (Reitter), Corticeus linearis (Fabricius), Corticeus pini (Panzer), Nemosoma elongatum (Linnaeus) and Dichrostigma flavipes (Stein) represent new records for both the Marmara Region and the Bursa province. It has been observed that eight species of insects, region Clerus mutillarius (Fabricius), Thanasimus formicarius (Linnaeus), Aulonium ruficorne (Oliver), Cylister elongatus (Thunberg), Hypnogyra angularis (Ganglbauer), Megalinus scutellaris (Fauvel), Corticeus fraxini (Kugelann) and Temnochila caerulea (Olivier), have set new records for both the Marmara Region and the Bursa province of Turkey. Additionally, the presence of these species in the Bursa province represents a new record for the area. These findings were obtained through extensive studies of the insect populations in these regions.Öğe Quercus spp. Scolytinae (Coleoptera: Curculionidae) fauna is found in forests: Oltu Sample(Bursa Technical University, 2024) Yazar, Zihni Burak; Gencal, Tutku; Sarıkaya, OğuzhanSome insect species to cause damage constantly, while others cause damage periodically. Among these pest in-sects, species belonging to the Scolytinae (Coleoptera: Curculionidae) family have a particularly important place. This study was conducted on Quercus spp. in Erzurum Oltu region. Scolytinae (Coleoptera: Curculionidae) fauna and flight periods of some important species in the forests are examined. After sampling studies conducted with red sticky traps, Anisandrus dispar, Scolytus intricatus, Scolytus rugulosus, Trypodendron signatum ve Xylebori-nus saxesenii species were identified. In addition, it was determined that the species detected were of new records for the Oltu region. The flight periods of Anisandrus dispar and Xyleborinus saxesenii, which had the highest population sizes in comparison to the other species, were determined. The findings provide compilation infor-mation on the management of harmful species and contribute to improving measures for sustainable forest man-agement and biodiversity conservation. This study is a basic reference that will enable the development of man-agement and conservation strategies for other regions with similar ecological conditions to Oltu region.
