This study was carried out in order to determine the soft scale insects (Hemiptera: Coccomorpha: Coccidae) species, their host plants, distribution areas, densities and infestation rates on fruit production areas of Diyarbakır and Elazığ Provinces in 2017-2018. As a result of the study, 7 soft scale species were determined on 12 fruit plants. The most common species and the widest host plant range was Parthenolecanium corni (Bouché, 1844) in the study areas. Sphaerolecanium prunastri (Boyer de Fonscolombe, 1834) and Didesmococcus unifasciatus (Archangelskaya, 1923) were determined to be the most important species in the region. Didesmococcus unifasciatus caused heavy infestation on almond, Prunus dulcis (Mill.) (Rosales: Rosaceae) trees (Scale 4) at rates of 3.1% and 0,9% in Çınar district of Diyarbakır and Sivrice district of Elazığ, respectively. Sphaerolecanium prunastri caused heavy infestation on apricots, Prunus armeniaca L. (Rosales: Rosaceae) at rates of 3.8% and 4.6% in Elazığ's Central and Baskil districts, which have significant apricot production areas.
本研究旨在确定2017-2018年迪亚巴克尔省和埃拉兹省水果产区的软鳞昆虫（半翅目：Coccomorpha：Coccidae）物种、寄主植物、分布区域、密度和侵扰率。研究结果表明，在12种果树上共鉴定出7个软鳞种。在研究区域内，最常见的物种和最广泛的寄主植物范围是Parthenolecanium corni（Bouché，1844）。Sphaerolecanium prunastri（Boyer de Fonscolombe，1834）和Didesmicococcus unifasciatus（Archangelskaya，1923）被确定为该地区最重要的物种。在Diyarbakır的Çınar区和Elazığ的Sivrice区，单束双球菌对杏仁树、杜李树（Rosales:Rosaceae）（4级）造成了严重的虫害，分别为3.1%和0.9%。在Elazığ的Central和Baskil地区，Sphaerolecanium prunastri对杏树Prunus armeniaca L.（玫瑰：蔷薇科）造成了严重的虫害，分别为3.8%和4.6%，这两个地区都有重要的杏树产区。

Host plant diversity causes differences in the biology and adaptation of insects. In this study, variations in some biological properties and adaptive antioxidative response of Myzus persicae (Sulzer,1776) (Hemiptera: Aphididae) on five Charleston pepper, Capsicum annuum L. (Solanaceae) cultivars were investigated under laboratory conditions (25±1°C, 60±5% RH). The lowest intrinsic rate of increase (r = 0.193 d-1) of M. persicae was estimated in the tested cohort fed with the Kanyon cultivar, while the highest intrinsic rate of increase (r = 0.248 d-1) was found on the Tufan cultivar. The cohort fed with Safkan cultivar exhibited the highest levels of GST-CDNB and EST-PNPA at 562.80 and 207.64 nmol/mg protein, respectively, whereas the cohort fed with Kanyon cultivar showed the lowest levels at 317.04 and 132.14 nmol/mg protein, respectively. Analysis of life table parameters and enzymatic/non-enzymatic antioxidant levels of M. persicae showed that among the cultivars we tested, the Tufan cultivar was the most preferred host by M. persicae, while Kanyon cultivar was a less suitable host.

The effects of Aspergillus niger Tiegh. (Ascomycota: Eurotiales) culture filtrate on Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949 (N) and Fusarium oxysporum f. sp. radicis lycopersici Jarvis & Shoemaker (Ascomycota: Hypocreales) (FORL) were investigated under controlled conditions on tomato between April and August 2022 in the Isparta province. The study consisted of 8 treatments; 1: N, 2: FORL, 3: N+A. niger, 4: FORL+A. niger, 5: N+FORL, 6: N+FORL+A. niger, 7: N+FORL+nematicide, 8: N+FORL+fungicide. In inoculation, 1000 M. incognita second juvenile larvae/1ml and 3X106 spore/ml FORL were used for each seedling according to treatment. Two days after inoculation, 10 ml of undiluted A. niger culture filtrate was applied to each potting soil. After 60 days, 0-9 gall and egg mass index, and 0-4 disease severity scale were evaluated. While the suppressive effect of A. niger culture filtrate on the gall and egg mass of M. incognita was found over 55%, disease severity was found to be over 25%. The highest suppressive effect on gall and egg mass was determined in N+FORL+nematicide, followed by N+FORL+A. niger. The disease severity of N+FORL+A. niger, N+FORL+nematicide, and N+FORL+fungicide has been determined to be lower than N+FORL and FORL.

Ditylenchus dipsaci (Kühn, 1857) Filipjev, 1936 (Rhabditida: Anguinidae) is one of the destructive agents of garlic and reduces yield and market value. One of the most practical and eco-friendly methods for nematode management is using resistant varieties. In the study, two endemic garlic species, Allium tuncelianum (Kolman) Ozhatay, Mathew & Siraneci and Allium macrochaetum subsp. macrochaetum Boiss. & Hausskn. (Alliaceae: Amaryllidaceae), 10 mutant and 32 landraces garlic genotypes, Allium sativum L. (Alliaceae: Amaryllidaceae) were investigated for their resistance reactions to D. dipsaci and effect of D. dipsaci on some plant growth parameters. All experiments were conducted at Atatürk Horticultural Central Research Institute in 2019-2020. None of the genotypes was found resistant to D. dipsaci, and reproduction factors, which ranged from 2.6 to 12.7, were grouped from susceptible to highly susceptible. The Tunceli garlic genotype had the lowest reproduction factor (2.6), 36.6% less than the highly susceptible Muğla6 genotype. Alata1, Muğla1, Muğla7 and Kula genotypes had the lowest decrease rate with nematode treatment at least in one of the plant growth parameters. The genotypes that had lower nematode multiplication and displayed better development under nematode infestation in this study are recommended for the field infested with D. dipsaci as sources for garlic breeding.

Tomato leafminer, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) is one of the most important tomato pests worldwide and causes 100% product loss if not controlled. Chemical insecticides, which have been overused for many years, have induced resistance in the pests and made it difficult to control their populations in the field. The use of biological agents that express insecticidal proteins, such as Bacillus thuringiensis, is an alternative to conventional insecticides to suppress pest populations. In this study, to recover novel B. thuringiensis strains from soil samples, a survey was conducted in Bilecik province in 2021. Thirteen local B. thuringiensis strains were isolated and the susceptibility of three different field populations (Samsun, İzmir, and Bilecik) of T. absoluta to these strains was evaluated. Bacillus thuringiensis B3 (Bt-B3) strain, which contains lepidopteran-active toxin genes, was more virulent for all T. absoluta populations tested. In addition, Samsun population was more sensitive to the B3 strain than İzmir and Bilecik. The LC50 values of Bt-B3 were determined to be 13.28, 26.06 and 24.24 ppm for Samsun, İzmir and Bilecik populations, respectively. Sequencing of the 16S rRNA gene region confirmed that the isolate was B. thuringiensis, while electron microscopy revealed that the isolate produced bipyramidal, cubic and spherical insecticidal proteins. The results of this study indicate that the isolate Bt-B3 appears to be a promising biocontrol agent for integrated pest management of T. absoluta in Türkiye.

In this study, insecticide residues on “Bayramiç Beyazı” nectarines were investigated with the use of QuEChERS method and LC-MS/MS analysis. Analytical method was verified through SANTE 11312/2021 Guidelines. The limit of quantification were below the MRLs for 12 insecticides. Method recovery was identified as 89.6%. Such a value was within the SANTE recovery (60-140%) limits. Nectarine samples were collected from Çanakkale open markets between 15 June-30 September, 2022 and analyzed at ÇOMÜ Agriculture Faculty-Pesticide Laboratory (Çanakkale-Türkiye). Abamectin, acetamiprid, deltamethrin, etoxazole, novaluron, pyriproxyfen, spirodiclofen, tetramethrin and thiacloprid residue levels were below the MRLs. On the other hand, dimethoate, imidacloprid and omethoate residues exceeded their MRLs only in one sample each. The maximum residues of acetamiprid, deltamethrin, etoxazole and novaluron were about 1/2, 1/5, 1/10, and 1/70 of the MRLs in one sample, respectively. Risk assessments revealed that exposure levels for adults were low (hazard quotient, HQ ≤ 1), with the exception of omehoate residues. Omethoate posed a chronic risk to human health through consumption of nectarines. For the remaining 11 insecticides, there was no risk for human health. However, the highest acute HQ were found for dimethoate even though its HQ was less than or equal to 1 The use of dimethoate is in the process of being banned in Türkiye, while omethoate (metabolite of dimethoate) is already banned. Presence of omethoate residue may be due to the degradation product of dimethoate.

The fat body is a major storage area for glycogen, lipid and protein. The trophocyte is the main cell of fat body and stores these macromolecules. The fat body consists of two parts; peripheral and perivisceral. Peripheral fat body is located below the integument while perivisceral fat body is around the digestive tract. The study was conducted in EGEMIKAL Analysis Laboratory and Histology Laboratory of Ege University between 2018 and 2020. The fat body contents of insects at all stages were examined comparatively in three selected sections through histochemical and ultrastructural studies. We identified macromolecules stored in the trophocytes. Both the granular form of proteins and asterisk structure of glycogen localized around the lipid droplets were observed clearly. It was found that accumulation of protein continued in the trophocytes, but glycogen accumulation decreased considerably in adults compared to all nymphal stages. We also found that larger lipid droplets were stored in the PF fat body, while glycogen and protein accumulation was much higher in the PV fat body. These results may contribute to understanding of the mechanisms underlying activities such as amino acid, nitrogen, lipid and carbohydrate metabolism and protein synthesis in insects.

Xenorhabdus Thomas & Poinar (Enterobacterales: Morganellaceae) and Photorhabdus Thomas & Poinar (Enterobacterales: Morganellaceae) bacteria are mutualistically associated with Steinernema Travassos, 1927 (Rhabditida: Steinernematidae) and Heterorhabditis Poinar, 1976 (Rhabditida: Heterorhabditidae) nematodes, respectively, and are known to produce several secondary metabolites that protect nematode-killed insects from different competitors. One of these compounds called “the scavenger deterrent factor” (SDF) is known to deter different arthropod, bird, and fish species from feeding on insects killed by Xenorhabdus or Photorhabdus bacteria. The effects of SDF from five different Xenorhabdus and one Photorhabdus species against the Norway rat, Rattus norvegicus (Berkenhout, 1769) (Rodentia: Muridae) were investigated using either a one-choice or two-choice experimental design during 2019-2020 in Aydın Adnan Menderes University. Rats were given four-day-old bacteria-killed Galleria mellonella (L., 1758) (Lepidoptera: Pyralidae) larvae and feeding behavior was observed and recorded. The results demonstrate that the Norway rat is deterred from feeding on insects killed by certain Xenorhabdus and Photorhabdus species and it is likely due to the distastefulness of these cadavers. Ecologically, the data suggest that insects killed by the entomopathogenic nematode/bacterium complex in nature may be protected from attack from insectivorous mammals, especially those that feed on soil-dwelling insects.

Hilara Meigen, 1822 (Diptera: Empididae) is a very difficult genus to identify in the Empididae, however, several researchers have divided the genus Hilara into fourteen species groups for convenience. The current study identified two new species of Hilara Meigen, 1822. The materials used in this study were collected in the vicinity of Nemrut Mountain Crater Lake from Bitlis Province in May 2021 by using a collection net. Hilara nemrutica spec. nov. (Hilara maura-group) and Hilara derenae spec. nov. (Hilara interstincta-group) from Bitlis province, Türkiye, are described, male genitalia and forelegs are illustrated, and distinguished from closely related congeners.

The geographic structure of Türkiye is well-suited for determining species diversity and interspecific variation as Türkiye has many regions with different altitudes and ecological characteristics. A large number of specimens belonging to the Helophoridae family belonging to the order Coleoptera were collected from different regions of Turkey between 2007-2021, examined and kept as museum material. Among the museum materials evaluated in terms of variation, Helophorus (Helophorus) aquaticus (L., 1758) species were seen to be both more common and more diverse in each region. In this study, male specimens varying in color, size, pronotum, tarsi, and genital structure were selected among the samples collected from different regions and geographic locations within the same locality. A total of 17 different morphological variations were identified and listed by examining the pronotum, elytra, tarsi, and aedeagophore structures. The relationships of these variations with altitude have been evaluated. As a result of this study, it has been determined that variations of the same species can coexist in the same locality, as well as similar variations in localities in different geographical regions. In addition, it was determined that the size of the insects increased as the altitude increased.
