RNA interference (RNAi) is a versatile genetic tool capable of selectively inhibiting the expression of any gene in a targeted organism. Its implementation holds great promise for safeguarding crops against insect pests and diseases. Vacuolar-ATPase represents an ideal target for RNAi-based pest management strategies since it is an enzyme essential for various physiological processes in insects. In this study, double-stranded RNA (dsRNA) was synthesized using an L4440 vector in Escherichia coli HT115 strain to silence the Vacuolar-ATPase proteolipid subunit mRNA in the Colorado potato beetle (Leptinotarsa decemlineata Say). To assess the effectiveness of RNAi, L. decemlineata larvae at different developmental stages were fed potato leaflets treated with dsRNA. The feeding bioassays using dsV-ATPase resulted in significant mortality rates, ranging from 45% to 77% across all of the instar stages of L. decemlineata. Furthermore, ingestion of dsRNAs by third- and fourth-instar larvae exerted significant effects on their body weight and foliage consumption. Notably, feeding the larvae dsV-ATPase led to a significant reduction in V-ATPase gene expression, confirming the efficacy of RNAi-mediated gene silencing in controlling L. decemlineata populations. These findings highlight the potential of RNAi-mediated gene silencing as a valuable strategy for managing L. decemlineata populations by targeting essential genes.
RNA干扰(RNAi)是一种多功能的遗传工具,能够选择性地抑制目标生物体中任何基因的表达。它的实施为保护作物免受病虫害带来了巨大的希望。液泡atp酶是昆虫多种生理过程所必需的酶,是基于rnai的害虫管理策略的理想靶标。本研究利用L4440载体在大肠杆菌HT115菌株中合成双链RNA (dsRNA),以沉默科罗拉多马铃薯虫液泡- atp酶蛋白脂亚基mRNA。为了评估RNAi的有效性,我们用dsRNA处理过的马铃薯小叶饲喂不同发育阶段的玉米叶蠹蛾幼虫。采用dsv - atp酶进行的饲养生物测定结果显示,在12叶螺旋藻的所有龄期,死亡率从45%到77%不等。此外,3龄和4龄幼虫摄取dsRNAs对其体重和叶片消耗有显著影响。值得注意的是,喂食dsV-ATPase导致V-ATPase基因表达显著降低,证实了rnai介导的基因沉默在控制小叶裂叶蝉种群中的作用。这些发现强调了rnai介导的基因沉默作为一种有价值的策略,可以通过靶向必需基因来管理L. decemlineata群体。

: Some biological characteristics and life table of Mulberry scale [ Pseudaulacaspis pentagona Targioni-Tozzetti (Hemiptera: Diaspididae)], which is an important thermophilic, invasive, and polyphagous pest of fruit trees, was investigated. The research has been conducted at 7 different temperatures (20.6, 23.2, 27.1, 29.0, 30.6, 31.3, 33.8 ℃ ) on two different mulberry species ( Morus alba and M. nigra ) in the climate chambers with fixed illumination regime (16 : 8 h) and relative humidity (60% ± 5%) conditions. The total longevity of female individuals on M. alba were 120.54, 86.79, 63.54, 57.51, 41.35, and 26.27 days, while 110.61, 99.62, 63.84, 70.92, 40.23, and 50.94 days on M. nigra . At these temperatures, the intrinsic rate of increase ( r ) of P. pentagona on M. alba were –0.012, 0.045, 0.078, 0.066, -0.022 day-1, while –0.019, 0.003, 0.052, 0.043, –0.039, and –0.076 day -1 on M. nigra , respectively. According to the study results, it was found that the population parameters of P. pentagona were generally higher for populations fed on white mulberry than for populations fed on black mulberry, at most of the different temperatures tested. Using the results of this study, it was concluded that black mulberry in regions with optimum temperatures between 23–29 ℃ and white mulberry in warmer areas (29 ℃ and above) would be more appropriate in terms of control P. pentagona .

Herewith, the current status of the inland waters ichthyofauna of Türkiye is revised, and an updated checklist of the freshwater lampreys and fishes is presented. As of November 2023, the freshwater ichthyofauna of Türkiye is known to consist of 427 species belonging to 20 orders, 37 families, and 97 genera. Among these, 21 species (4.9%) are alien, and 215 species (50.4%) are considered endemic to Türkiye. The orders with the largest numbers of species in the ichthyofauna of Türkiye are the Cypriniformes (297 species, 69.6%), followed by the Cyprinodontiformes (26 species, 6.1%), the Salmoniformes (25 species, 5.9%), the Gobiiformes (20 species, 4.7%), the Siluriformes (13 species, 3.0%), and the Clupeiformes (9 species, 2.1%). At the family level, the Leuciscidae has the greatest number of species (126 species; 29.8% of the total species), followed by Nemacheilidae (63 species, 14.8%), Cyprinidae (59 species, 13.8%), Cobitidae (29 species, 6.8%), Salmonidae (25 species, 5.9%), Aphanidae (23 species, 5.4%), Gobiidae (20 species, 4.7%), and Gobionidae (15 species, 3.5%). According to IUCN Red List criteria, among 403 naturally distributed species (alien species not included), four fish species are extinct, and 99 species (24.4%) are classified as threatened extinctions, including 28 (6.9%) CR, 44 (10.8%) EN, and 27 (6.7%) VU. After the latest checklist published in 2020, a total of 56 species, including 26 newly identified species from Türkiye and 30 new records documented from Turkish inland waters, were added. By the way, a total of 17 species have been excluded, mostly because of synonymization.
在此,修订了台湾内陆水域鱼类学的现状,并提出了一份更新的淡水七鳃鳗和鱼类清单。截至2023年11月,已知的淡水基耶岛鱼系有427种,隶属于20目37科97属。其中,外来种21种(4.9%),特有种215种(50.4%)。鲤科鱼类目中种类最多的目是鲤形目(297种,69.6%),其次是鲤形目(26种,6.1%)、鲑形目(25种,5.9%)、鱼形目(20种,4.7%)、志留鱼形目(13种,3.0%)和棍形目(9种,2.1%)。在科水平上,Leuciscidae有最多的物种(126种);占总种数的29.8%),其次为Nemacheilidae(63种,14.8%)、Cyprinidae(59种,13.8%)、cobitiae(29种,6.8%)、Salmonidae(25种,5.9%)、Aphanidae(23种,5.4%)、Gobiidae(20种,4.7%)和Gobionidae(15种,3.5%)。根据IUCN红色名录标准,在403种自然分布物种(不包括外来物种)中,有4种已灭绝,99种(24.4%)被列为濒危物种,其中CR 28种(6.9%),EN 44种(10.8%),VU 27种(6.7%)。在2020年发布的最新清单之后,总共增加了56个物种,其中包括26个新发现的来自 rkiye的物种和30个来自土耳其内陆水域的新记录。顺便说一下,共有17种被排除在外,主要是因为同义。

Multidisciplinary approaches for the conservation of endangered species have great importance in preparing management plans. In addition to ecological and population demographic parameters, genetic data provide vital information for conservation management plans for a species. The Hermann's tortoise (Testudo hermanni) suffers from illegal trade, fires, habitat fragmentation and destruction, and therefore, the genetic diversity of the regional populations has been affected. It was aimed herein to impart knowledge on the population genetic structure of T. hermanni boettgeri, listed as near threatened by the International Union for Conservation of Nature Red List as a subspecies and has limited distribution in European Türkiye. A study was conducted of 15 microsatellite loci of 221 tortoises from 15 different localities in the Thrace region in Türkiye. All of the examined loci were polymorphic, and the number of alleles varied from 2 to 13. The quantity of private alleles (Pa) at the localities ranged from 0 to 6. The average gene diversity was 0.31 (range: 0.25-0.38). The highest levels of allelic richness, private alleles, and genetic diversity (Ar, Pa, He) were observed at localities 3 and 7, close to each other. The total population (p < 0.001) and 12 of the 15 studied localities diverged from the Hardy-Weinberg equilibrium. Of the 15 localities studied, 6 had significantly different inbreeding coefficients. Furthermore, a 2-phased model of mutation (TPM) (p < 0.001) detected a recent bottleneck in the population. The population genetic results identified 8 groups with significant genetic structure (F$_{ST}$ = 0.166, p < 0.01) in 2 large clusters (K = 2).
保护濒危物种的多学科方法在制定管理计划方面具有重要意义。除了生态和种群统计参数外,遗传数据还为物种保护管理计划提供了重要信息。赫尔曼陆龟(Testudo hermanni)遭受非法贸易、火灾、栖息地破碎和破坏,因此,区域种群的遗传多样性受到影响。该物种被国际自然保护联盟(iucn)列为近危亚种,在欧洲大陆的分布有限。对来自斯里兰卡色雷斯地区15个不同地点的221只象龟的15个微卫星位点进行了研究。所有基因座均呈多态性,等位基因数量在2 ~ 13个之间。各地点的私有等位基因数量(Pa)在0 ~ 6之间。平均基因多样性为0.31(范围为0.25 ~ 0.38)。等位基因丰富度、私有等位基因丰富度和遗传多样性(Ar、Pa、He)在3号和7号位点均达到最高水平。总体(p < 0.001)和15个研究地点中的12个偏离Hardy-Weinberg平衡。在研究的15个地点中,6个地点的近交系数差异显著。此外,两阶段突变模型(TPM) (p < 0.001)检测到种群中最近的瓶颈。群体遗传结果显示,在2个大聚类(K = 2)中,8个群体遗传结构显著(F$_{ST}$ = 0.166, p < 0.01)。

: Heavy metal toxicity is a significant threat to human health and the environment. Contamination of the food chain with heavy metals in water sources may impact the health of consumers adversely. This study aimed to determine the concentrations of Pb, Cd, Cr, Cu, and Zn in the invasive fish species Carassius gibelio inhabiting two important lakes in Türkiye: Lake Beyşehir and Lake Eğirdir, from the Lake District Region and assess any health risks posed by the consumption of these species. For this purpose, C. gibelio species were obtained from two lakes in dry and rainy seasons and heavy metal concentrations were determined via ICP-OES analyses. The Cd concentrations in the muscle samples obtained from both lakes were below the analysis limits. The mean heavy metal concentrations (mg/kg) in the Beyşehir and Eğirdir lake samples were found as Pb: 0.32, Cr: 0.09, Cu: 0.52, and Zn: 6.88 and Pb: 0.88, Cr: 0.08, Cu: 0.46, and Zn: 12.6, respectively. The average heavy metal concentrations in the muscle tissues were below the national/international legislation limits, and the estimated daily intake (EDI), target hazard quotients (THQs), total THQs (TTHQs), and carcinogenic rates (CRs) did not exceed these limits. The results suggested that the consumption of these invasive fish species from these two lakes might not pose any potential health risk for consumers. Transference values (TF) for the digestive tract were also calculated, and biomagnification was determined for Pb, Cd, and Cr. Risk assessment studies are very important in terms of evaluating the effects of fish consumption on human health via applying different indices. This is the first study in which heavy metal concentrations were determined simultaneously in Lake Beyşehir and Lake Eğirdir, and the public health risk of consuming their invasive fish species was estimated.
