In the present study, the toxicities of seven entomopathogenic fungal isolates, Beauveria bassiana (ARSEF-4984), Isaria farinosa (ARSEF-3580), Isaria fumosorosea (ARSEF-4501), Lecanicillium muscarium (ARSEF-5128), L. muscarium (ARSEF-972), Lecanicillium lecanii (TR38/11) and L. muscarium (Ve6), were tested against the adults of granary weevil, Sitophilus granarius (L., 1758) (Coleoptera: Curculionidae), under laboratory conditions (25±1°C, 75±5% RH and 14h light:10h dark). Studies were conducted in Atatürk University (Erzurum, Türkiye), in 2018. Fungal isolates were sprayed to adults at two different conidial concentrations (1×105 and 1×107 ml-1). Mortality percentages were observed on the 2nd, 4th, 6th, 8th, and 10th days of treatment. A commercial isolate of L. muscarium were used as positive control and sterile water+0.25% Tween 20 used as negative control. The results demonstrated that the mortality rates of S. granarius adults treated with entomopathogenic fungi ranged from 1.01% to 98.9% across 10-day period. Higher concentration and longer exposure periods resulted in increasing virulence on the adult individuals. Among the strains tested, at 1×107 ml-1 concentration, I. fumosorosea, L. muscarium (ARFES-5128) and L. lecanii isolates displayed 97.85%, 94.62% and 93.58% cumulative mortalities respectively, on S. granarius adults by the 10th day of the experiment. These three isolates are regarded as highly promising biological control agents.

Entomopathogenic nematodes (EPN) are a widely used biological control agent. The aim of the study was to detect efficacy and mortalities of some EPN stored at different temperatures and periods. Three EPN species were used in the study. They were Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: Heterorhabditidae) HBH hybrid strain, Steinernema carpocapsae Weiser, 1955 TUR-S4 isolate and Steinernema feltiae Weiser, 1955 (Rhabditida: Steinernematidae) TUR-S3 isolate. The species were kept at 4, 15, 25 and 35°C for 7, 14 and 21 days. Subsequently, these species were applied at a dose of 15 Infective juveniles on Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae) larvae. The study was carried out in laboratory conditions in 2023. As a result, HBH and TUR-S4 kept at 25°C for 14 days and TUR-S3 for 21 days showed the highest virulence as 93.33%. Mortality rates of the EPN species kept at the specified temperatures were also determined. The results have showed that the highest mortality rates for the HBH, TUR-S4 and TUR-S3 isolates were 11.96% on the 14th day at 35°C, 19.81% on the 21st day at 25°C and 7.39% on the 21st day at 35°C, respectively. This study is an important step in determining suitable temperature conditions for storing and transporting EPN.

This research was conducted to investigate the saproxylic Coleoptera fauna found in oak trees of different ages in Mersin/Gülnar in the Eastern Mediterranean Region in 2017. Fourty-five window traps were used to sample the beetles on the oak trees. Traps were checked five times, once a month, from June to October. In total, 13 217 individuals from the order Coleoptera were collected and 242 saproxylic beetle species belonging to 44 families were found. In the material, 33 beetle species were identified as new records for the Turkish fauna. Most beetle species were from the Buprestidae (24 species), Anobiidae (23 species) and Tenebrionidae (18 species) families. The highest numbers of individuals were from the Dermestidae (2 354), Elateridae (2 325) and Curculionidae (1 531) families. The highest number of individuals were Xyleborus dryographus (Ratzeburg, 1837) (Curculionidae) and Cardiophorus (Cardiophorus) parvulus Platia & Gudenzi, 2000 (Elateridae) with 1 109 individuals each. Three species were found; namely Protaetia (Eupotosia) mirifica (Mulsant, 1842), Chromovalgus peyroni (Mulsant, 1852) (Cetonidae) and Propomacrus bimucronatus (Pallas, 1781) (Euchiridae), which appear on the IUCN European and Mediterranean red list as Vulnerable (VU).

Wireworms, Agriotes spp. Eschscholtz, 1829 (Coleoptera: Elateridae) are among the most harmful soil-borne insect pests and significantly reduce potato yields under heavy infestations. The presence of wireworm species on potatoes in potato growing areas is not fully known in the provinces of Türkiye. Therefore, this research aimed to identify wireworms molecularly and evaluate their biodiversity in potato growing ecosystems. Here, the first extensive field survey was carried out in Türkiye's principal potato-growing regions in 2019 and 2020 (Afyon, Bolu, İzmir, Kayseri, Konya, Niğde, and Sivas). Species identification of wireworms was performed using DNA barcoding approach based on the fragment of mitochondrial cytochrome c oxidase subunit I (COI). Samples were collected from 400 potato fields, and 510 larval specimens were obtained. The presence of wireworms was confirmed for Afyon, Bolu, Kayseri, Konya, and Sivas provinces, with an average prevalence of 13.5%, while no positive samples were recovered from Niğde and İzmir. Agriotes sputator (L.,1758) (Coleoptera: Elateridae) was the most prevalent species in surveyed areas. The Shannon index of wireworm species was found to be as 0.59, which implies a low degree of biodiversity of wireworms in potato fields.

The peach potato aphid, Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae), a vector of many plant virus diseases, causes damage to its wide range of hosts by direct feeding. Chemical control has been the primary method to control this species, and the intensive use of insecticides has led to the development of resistance. In this study, conducted between the years 2017-2019, firstly resistance ratio of five M. persicae populations from Antalya, Türkiye were determined by leaf-dip bioassay method. The field populations showed significant resistance to thiamethoxam (between 201-332 fold) and lambda-cyhalothrin (between 50-103 fold) when compared to susceptible population. To identify whether resistance mediated by mutations in sodium channel and nicotinic acetylcholine receptor, DNA regions that encompass “mutation hot-spot” were sequenced. This revealed no population contained R81T mutation that has been previously linked with neonicotinoid resistance. As to synthetic pyrethroid resistance, the L1014F kdr mutation was fixed in all field populations. This study is the first description of kdr mutation in M. persicae populations from Türkiye. Bioassay results also indicated that the toxicity of thiamethoxam and lambda-cyhalothrin mixture was higher than that of lambda-cyhalothrin alone. Our findings can make significant contributions to M. persicae resistance management.

This study was carried out to determine tachinid (Diptera: Tachinidae) parasitoids obtained from some hemipterous hosts in Adana, Ankara, Hatay, Konya and Uşak provinces of Türkiye between 2001 and 2020. For this purpose, adult hemipters were collected from perennial arboreal and annual herbaceous plants. The samples were brought to the laboratory and cultured on the relevant host plant material. As a result of the study, 11 tachinid species were determined from 10 different hemipterous hosts. Of these, four parasitoid-host couples are new records. These were Aelia rostrata Boheman, 1852 (Hemiptera: Pentatomidae) and Scantius aegyptius (L., 1758) (Hemiptera: Pyrrhocoridae) for Gymnosoma clavata (Rohdendorf, 1947) (Diptera: Tachinidae), Dolycoris baccarum (L., 1758) (Hemiptera: Pentatomidae) for Eulabidogaster setifacies (Rondani, 1861) (Diptera: Tachinidae) and Piezodorus lituratus (Fabricius, 1794) (Hemiptera: Pentatomidae) for Cylindromyia rubida (Loew, 1854) (Diptera: Tachinidae). Also, eight new hosts were reported for the first time in Türkiye. In addition, host information and distributions of each parasitoid are presented in the study.

This study was conducted to determine the malathion resistance levels of two important stored grain pest beetles, Sitophilus oryzae L., 1763 and Sitophilus granarius L., 1758 (Coleoptera: Curculionidae), collected from different provinces of Türkiye in the years 2017-2018. To control these pests, chemical insecticides have been widely used for a long time as a grain protectant in farmer warehouses, flour mills, or silos in many countries, including Türkiye. In the current study, insects were exposed to malathion for 24 hours to determine resistance rates. The highest resistance ratio to malathion in S. oryzae was found in the Adana-Kartepe population with 5.73-fold, and the lowest resistance was found in the İstanbul- Büyükçekmece population with 1.57-fold. While the Konya-Alibeyhöyüğü population of S. granarius had the highest resistance ratio of 6-fold, the lowest resistance rate of 2.54-fold was found in the population obtained from the same location but from a different warehouse. According to this study, we found that slight resistance developed in the populations of S. oryzae and S. granarius in Türkiye. In order to prevent the occurrence of resistance due to synthetic insecticides used against stored product pests, it is thought that various insecticide groups with different mechanisms of action should be used.
本研究对2017-2018年在浙江省不同省份采集的两种重要储粮害虫米象甲(Sitophilus oryzae L.， 1763)和粒象甲(Sitophilus granarius L.， 1758)的马拉硫磷抗性进行了测定。为了控制这些害虫，化学杀虫剂作为谷物保护剂在许多国家被广泛应用于农民仓库、面粉厂或筒仓中，包括 rkiye。在目前的研究中，昆虫暴露于马拉硫磷24小时，以确定抗性率。Adana-Kartepe种群对马拉硫磷的抗性最高，为5.73倍，İstanbul- b yy k ekmece种群的抗性最低，为1.57倍。同一地点不同仓库的黑麦黑麦Konya-Alibeyhöyüğü种群的耐药率最高，为6倍，最低为2.54倍。根据本研究，我们发现稻瘟病菌和稻瘟病菌在稻瘟病菌种群中产生了轻微的抗性。为防止合成杀虫剂对储粮害虫产生抗药性，应选用不同作用机制的不同杀虫剂类群。

To control these pests, chemical insecticides have been widely used for a long time as a grain protectant in farmer warehouses, flour mills, or silos in many countries, including Türkiye. In the current study, insects were exposed to malathion for 24 hours to determine resistance rates. The highest resistance ratio to malathion in S. oryzae was found in the Adana-Kartepe population with 5.73-fold, and the lowest resistance was found in the İstanbul- Büyükçekmece population with 1.57-fold. While the Konya-Alibeyhöyüğü population of S. granarius had the highest resistance ratio of 6-fold, the lowest resistance rate of 2.54-fold was found in the population obtained from the same location but from a different warehouse.

In this study, sublethal doses of lambda-cyhalothrin to the species Aphis fabae (Scopoli, 1763), Myzus persicae (Sulzer, 1776) and Acyrthosiphon pisum (Harris, 1776) (Hemiptera: Aphididae) were determined, and the effects of these doses on the life cycles of the species were revealed and evaluated. The lethal effects of different concentrations (0.3125, 0.625, 1.25, 2.5, 5, 10 and 20 µL L-1) prepared by distillated water of lambda-cyhalothrin on the species were determined according to Abbott. Based on the results obtained, the effects of LC30 and LC40 concentrations of the insecticide on the life cycles of the species were determined. The insecticide caused different mortality rates in the species. The sublethal concentrations of the insecticide were found to be effective for the life cycles of the species. In all three species, intrinsic rate of increase (rm), net reproduction rate (R0) and gross reproduction rate (GRR) values were found to decrease when insecticide was applied. The results will provide guidance to researchers working in this specific field. However, it would be beneficial to replicate this study under field conditions to obtain clear information.

The Hatay yellow strain of silkworm, Bombyx mori L., 1758 (Lepidoptera: Bombycidae) which produces cocoons with an extraordinary yellow color range, is one of the most important endemic and endangered cultural assets in Türkiye. In this study, intense fungal infection and many deaths were detected in the breeding trays in the Hatay yellow breed production facility. An entomopathogenic fungus was isolated from Hatay yellow strain cadavers collected in 2020. According to the morphological and molecular analysis results of the isolate, which was brought into pure culture, it was identified as Beauveria bassiana (Bals.-Criv.) Vuill. (Ascomycota: Hypocreales), the isolate HS1. Phylogenetic analysis results showed that the HS1 strain was very similar (99 %) to the isolates of B. bassiana KJ6 (Iran) and ARSEF 300 (Europe). The concentration-response test using 1 × 104-8 conidia/ml concentrations produced LC50 values of the new strain of 1.2 × 103 and 0.6 × 106 conidia/ml within 7 days against the larvae of Hatay yellow strain and hybrid strain of silkworm, respectively. The results indicated that the virulence of the B. bassiana HS1 strain to the Hatay yellow strain was much more severe and that the Hatay yellow strain had to fight it to survive.
桑蚕的Hatay黄色品系Bombyx mori L.，1758（鳞翅目：Bombycidae）产茧具有非凡的黄色范围，是土耳其最重要的地方性和濒危文化资产之一。在这项研究中，在哈泰黄品种生产设施的繁殖托盘中检测到强烈的真菌感染和许多死亡。从2020年采集的哈泰黄色菌株尸体中分离出一种昆虫病原真菌。经形态学和分子生物学分析，鉴定为球孢白僵菌。（子囊菌门：Hypocreales），分离株HS1。系统发育分析结果表明，HS1菌株与B.bassiana KJ6（伊朗）和ARSEF 300（欧洲）的分离株非常相似（99%）。采用1×104-8分生孢子/ml浓度的浓度响应试验，在7天内，新菌株对哈代黄株和杂交株的幼虫分别产生了1.2×103和0.6×106分生孢子/ml的LC50值。结果表明，球孢B.bassiana HS1菌株对哈泰黄菌株的毒力要严重得多，哈泰黄必须与之对抗才能存活。
