The cherry tree borer, Synanthedon bicingulata (Staudinger), is considered a major boring pest on tree species belonging to the genus Prunus (Family Rosaceae). Among Prunus species, Prunus × yedoensis, the host species of S. bicingulata, is one of the most abundant roadside trees in the Republic of Korea. However, the lack of information on the infestation characteristics of S. bicingulata on P. × yedoensis hinders effective management of the roadside trees compared to those in orchards. This study aimed to investigate the infestation characteristics of S. bicingulata in relation to cracks, a common abiotic injury in roadside trees. During 2023, field investigations were conducted in three locations in the Republic of Korea, and a total of 211 infested P. × yedoensis trees were investigated. For the investigation, we counted the number of larval infestations of S. bicingulata in all P. × yedoensis planted as roadside trees. The infestation rate increased with the increasing diameter at breast height. Higher infestation rates by S. bicingulata were found in lower parts and on the south-facing tree trunk, where cracks were more concentrated. Also, significantly higher densities of S. bicingulata larval infestations occurred inside cracks than those outside. In consequence, targeting and managing cracks in tree trunks, particularly in the lower parts and on the south-facing side, is a key tactic to reduce larval infestation of S. bicingulata.

樱桃树蛀虫,Synanthedon bicingulata (Staudinger),被认为是一种主要的害虫,属于樱桃属(蔷蔷科)的树种。在李属树种中,李属(Prunus x yedoensis)是韩国最丰富的路边树种之一,是双星李属(S. bicingulata)的寄主树种。然而,相对于果园,由于缺乏对林旁树木侵染特征的了解,阻碍了对林旁树木的有效管理。摘要本研究旨在探讨路边树木常见的非生物性病害——裂缝对双曲曲霉(S. bicingulata)的侵害特征。2023年,在韩国3个地点进行了实地调查,共调查了211株黄杨。在调查中,我们统计了所有种植在路边的紫杉树中,双翅叶蝉的幼虫侵染数。侵染率随胸径的增加而增加。较低的树干下部和朝南的树干上,裂缝较集中,双翅蚜的侵染率较高。此外,裂缝内的双翅蚜幼虫密度明显高于裂缝外。因此,针对和管理树干上的裂缝,特别是在较低的部分和朝南的一侧,是一个关键的策略,以减少小蠹幼虫的侵扰。

Microbiome research has advanced in recent years due to technological developments and significant cost reductions in analytical methodologies. Research on the microbiota in insects is limited compared with other animal species. This study was performed to compare the bacterial compositions in mealworms (Tenebrio molitor) among different farms in Korea. For this study, mealworm larval samples were collected from three different farms in Korea, and genomic DNA was extracted. The extracted DNA was sequenced using primers from the V3–V4 region of 16S rRNA to identify the bacterial community. The raw data were analyzed using the QIIME2 pipeline to determine the diversity, taxonomy, and differential abundance among groups. We comprehensively characterized insect-associated bacterial families in 23 individuals belonging to six phyla by sequencing 32,827 amplicons of 16S rRNA genes. A total of 637,204 sequence reads from the live and dead larvae of T. molitor from three different farms were obtained. After quality control, denoising, merging, and chimera removal, a total of 637,204 reads were obtained, identifying 32,827 bacterial amplicon sequence variants in the live and dead larvae of T. molitor from three different farms. The insect microbiota was dominated by Firmicutes (52.6%) and Proteobacteria (46.3%).

近年来,由于技术的发展和分析方法成本的显著降低,微生物组研究取得了进展。与其他动物物种相比,对昆虫微生物群的研究是有限的。本研究比较了韩国不同农场粉虫(tenbrio molitor)的细菌组成。在本研究中,我们从韩国三个不同的农场采集了粉虫幼虫样本,并提取了基因组DNA。利用16S rRNA V3-V4区的引物对提取的DNA进行测序,鉴定细菌群落。使用QIIME2管道对原始数据进行分析,以确定组间的多样性、分类和差异丰度。我们通过测序32,827个16S rRNA基因扩增子,全面表征了属于6门的23个个体的昆虫相关细菌家族。从3个不同养殖场的活幼虫和死幼虫中获得637204条序列。经过质量控制、去噪、合并和嵌合体去除,共获得637,204个reads,鉴定出来自三个不同养殖场的molitor活幼虫和死幼虫的32,827个细菌扩增子序列变异。昆虫微生物群以厚壁菌门(52.6%)和变形菌门(46.3%)为主。

Understanding how insects coordinate immune responses with metabolic demands is key to elucidating host–pathogen interactions. Here, we performed integrated mRNA and miRNA transcriptomic profiling in Drosophila melanogaster following infection with the entomopathogenic fungal Beauveria bassiana at 12 and 24 h post-infection (hpi). Differential expression and time-series clustering revealed dynamic transcriptional reprogramming, including early immune activation, sustained oxidative stress responses, and delayed metabolic compensation. To investigate post-transcriptional regulation, we constructed high-confidence miRNA–mRNA networks by intersecting differentially expressed miRNAs and mRNAs with dual-target predictions from miRanda and RNAhybrid, retaining only canonical repression pairs (upregulated miRNAs with downregulated targets and vice versa). At 12 hpi, the network comprised 91 interactions involving 18 miRNAs and 72 mRNAs. Key regulators such as dme-miR-34-5p and dme-miR-285-5p targeted genes in immune and metabolic pathways, including Toll/IMD signaling, glutathione metabolism, and lysosome function. By 24 hpi, the network contracted to 23 interactions (12 miRNAs and 22 mRNAs), with regulatory focus shifting toward amino acid metabolism, ER stress response, and redox homeostasis. Distinct sets of upregulated and downregulated miRNAs mediated temporally resolved targeting of biosynthetic and immune-related genes. These results reveal a stage-specific, miRNA-mediated regulatory architecture that balances immune activation with metabolic adaptation. Our work presents a time-resolved dual-omics map of the Drosophila immune response to fungal infection, offering new insights into conserved regulatory mechanisms and host–pathogen interactions.

了解昆虫如何协调免疫反应与代谢需求是阐明宿主-病原体相互作用的关键。在这里,我们对感染球孢白僵菌(Beauveria bassiana)后12和24 h的黑腹果蝇进行了整合的mRNA和miRNA转录组分析。差异表达和时间序列聚类揭示了动态转录重编程,包括早期免疫激活、持续氧化应激反应和延迟代谢补偿。为了研究转录后调控,我们构建了高置信度的miRNA-mRNA网络,将差异表达的mirna和mrna与miRanda和RNAhybrid的双靶标预测相交,仅保留规范抑制对(上调mirna与下调靶标,反之亦然)。在12 hpi时,该网络包含91个相互作用,涉及18个mirna和72个mrna。关键调控因子如dme-miR-34-5p和dme-miR-285-5p在免疫和代谢途径中的靶向基因,包括Toll/IMD信号,谷胱甘肽代谢和溶酶体功能。到24 hpi时,该网络收缩为23个相互作用(12个mirna和22个mrna),调控重点转向氨基酸代谢、内质网应激反应和氧化还原稳态。不同的上调和下调的mirna介导暂时解决靶向生物合成和免疫相关基因。这些结果揭示了一个阶段特异性,mirna介导的调节结构,平衡免疫激活与代谢适应。我们的工作提出了果蝇对真菌感染免疫反应的时间分辨双组学图谱,为保守的调节机制和宿主-病原体相互作用提供了新的见解。

The monsoonal (seasonal) tropics of northern Australia is a global center of ant diversity but is unrecognized as such because the great majority of its species is undescribed. Here, we document undescribed diversity in the Meranoplus unicolor Forel complex, which is formally recognized as a single species occurring throughout central and northern Australia. We obtained 80 CO1 sequences from specimens collected from throughout the taxon's range, and from these we recognize 42 species, 33 from the monsoonal zone. None of the species appears to be M. unicolor. Most of the species have very limited distributions and many are represented by single collections; given that no specimens are available for most of central and northern Australia, the total number of species in the complex is likely to be in the order of twice as many as we have recognized. Our findings provide further evidence that the ant fauna of monsoonal Australia contains several thousand species, which is many more than current estimates for any other regional fauna.

澳大利亚北部的季风(季节性)热带地区是蚂蚁多样性的全球中心,但由于其绝大多数物种未被描述,因此未得到承认。在这里,我们记录了Meranoplus单色Forel复合体中未描述的多样性,该复合体被正式认定为单一物种,分布在澳大利亚中部和北部。我们从整个分类群范围内收集的标本中获得了80个CO1序列,从中我们识别出42个物种,其中33个来自季风带。没有一个物种看起来是M. unicolor。大多数物种的分布非常有限,许多物种以单一集合为代表;考虑到澳大利亚中部和北部的大部分地区都没有标本,这个复杂的物种总数可能是我们所认识到的两倍。我们的发现提供了进一步的证据,证明季风澳大利亚的蚂蚁动物群包含数千种,这比目前估计的任何其他区域动物群都要多。

Reproductive competence in male bumblebees (Bombus terrestris) is contingent upon the precise orchestration of spermatogenesis, governed by the temporal regulation of genes involved in mitochondrial metabolism and flagellar assembly. Although bumblebees serve as ecologically and agriculturally indispensable pollinators, the molecular underpinnings of testicular development in drones remain poorly elucidated. We conducted stage-resolved transcriptomic profiling of B. terrestris drone testes at three critical post-eclosion intervals—Days 1, 5, and 9—to capture gene expression dynamics associated with sperm development. A total of 620 differentially expressed genes (DEGs) were identified and grouped into four discrete temporal expression clusters. Gene Ontology (GO) and KEGG pathway enrichment analyses revealed substantial transcriptional reprogramming associated with mitochondrial bioenergetics, cytoskeletal remodeling, and flagellar motility. This transcriptomic analysis of B. terrestris drone testes identified a precise, stage-specific transcriptional program involving early proliferation and detoxification (Day 1), mitochondrial metabolic priming (Day 5), and robust activation of ATP synthesis and flagellar assembly (Day 9). Despite a slight temporal offset between molecular (Day 9) and physiological maturity (peak mating at Day 7), identified key genes—including inositol 2-dehydrogenase, flagellar attachment zone protein, flagellar hook-length control protein, and axonemal dynein intermediate chain—serve as candidate molecular biomarkers for reproductive fitness. These findings provide foundational genomic resources for advancing pollinator breeding and conservation strategies.

雄性大黄蜂(Bombus terrestris)的生殖能力取决于精子发生的精确安排,由涉及线粒体代谢和鞭毛组装的基因的时间调节所控制。虽然大黄蜂是生态和农业上不可或缺的传粉者,但雄蜂睾丸发育的分子基础仍不清楚。我们在三个关键的羽化后间隔(第1天、第5天和第9天)进行了陆地小蠊雄蜂睾丸的转录组分析,以捕获与精子发育相关的基因表达动态。共鉴定了620个差异表达基因(DEGs),并将其分为4个离散的时间表达簇。基因本体(GO)和KEGG途径富集分析揭示了与线粒体生物能量学、细胞骨架重塑和鞭毛运动相关的大量转录重编程。该转录组学分析发现了一个精确的、特定阶段的转录程序,涉及早期增殖和解毒(第1天)、线粒体代谢启动(第5天)和ATP合成和鞭毛组装的强大激活(第9天)。尽管分子成熟度(第9天)和生理成熟度(第7天达到交配高峰)之间存在轻微的时间偏差,但已确定的关键基因——包括肌醇2-脱氢酶、鞭毛附着区蛋白、鞭毛钩长控制蛋白和轴索动力蛋白中间链——可作为生殖适应性的候选分子生物标志物。这些发现为推进传粉媒介的育种和保护策略提供了基础的基因组资源。

Many insect species are at risk of extinction due to habitat degradation and loss, the introduction of invasive species, and climate change. Butterfly populations, in particular, have declined worldwide. Our study analyzed changes in the six landscape features across sites where 18 threatened butterfly species were recorded over 40 years (1987–2018). We observed a significant expansion of developed areas accompanied by a marked decline in agricultural areas, leading to notable changes in habitat composition. Additionally, areas supporting more than two endangered (EN) butterflies, along with vulnerable (VU) and near-threatened (NT) butterflies, showed a significant reduction in grassland cover, underscoring the importance of grassland for sustaining threatened butterflies. Following a review of the status of threatened butterflies in Korea, we examined the impacts of habitat change, forest succession, cultural changes (e.g., burial preferences), and climate change on the decline of butterflies in Korea.

由于栖息地的退化和丧失、入侵物种的引入和气候变化,许多昆虫物种面临灭绝的危险。特别是蝴蝶的数量在世界范围内已经下降。我们的研究分析了40年来(1987-2018年)记录的18种濒危蝴蝶物种的6个景观特征的变化。我们观察到发达地区的显著扩张伴随着农业地区的显著减少,导致栖息地组成的显著变化。此外,支持两种以上濒危(EN)蝴蝶以及易危(VU)和近危(NT)蝴蝶的地区,草地覆盖显著减少,强调了草地对维持受威胁蝴蝶的重要性。在回顾了韩国濒危蝴蝶的现状之后,我们研究了栖息地变化、森林演替、文化变化(如埋葬偏好)和气候变化对韩国蝴蝶数量下降的影响。

Sustainable approaches to managing poultry waste, such as its use as manure, are urgently required to address emerging concerns under increasing demand for poultry products. Incorporating coffee marc and bentonite as part of the waste processing by Tenebrio molitor (TM) larvae presents effective strategies for addressing these challenges. The present study investigated the capacity of 4th and 6th instar TM larvae to biodegrade poultry manure following treatment with coffee marc or coffee marc and bentonite, based on ammonia (NH3) contents and physicochemical characteristics of poultry manure. The three treatments adopted in the present study included 2 kg of poultry manure (T1), 1 kg of poultry manure + 1 kg of coffee marc (T2), and 1 kg of poultry manure + 0.9 kg of coffee marc + 0.1 kg of bentonite as a basis of 0.2 kg of 4th or 6th instar TM larvae (T3). The 4th and 6th instar TM larvae had no significant effect on biodegradation capacity. Nevertheless, a significant difference in NH3 flux occurred during the experiments. In the 4th instar TM larvae treatments, significant differences in pH, total nitrogen (TN), and ADF occurred among all treatments; conversely, in the manure treated with coffee marc and bentonite, 6th instar TM larvae had significant effects on pH, dry matter (DM), TN, ADF, and NDF content compared with only poultry manure. In conclusion, 6th instar TM larvae reared on poultry manure with coffee marc and bentonite could decrease the environmental impact during composting.

迫切需要采取可持续的方法来管理家禽废物,例如将其作为粪便使用,以解决对家禽产品需求不断增加的新问题。将咖啡渣和膨润土作为tenbrio molitor (TM)幼虫处理废物的一部分,是解决这些挑战的有效策略。本研究基于禽粪氨(NH3)含量和理化特性,研究了咖啡渣和膨润土分别处理4龄和6龄TM幼虫对禽粪的生物降解能力。本试验采用3种处理,分别为2 kg禽粪(T1)、1 kg禽粪+ 1 kg咖啡渣(T2)和1 kg禽粪+ 0.9 kg咖啡渣+ 0.1 kg膨润土,4、6龄TM幼虫(T3)为0.2 kg。4、6龄TM幼虫对生物降解能力无显著影响。然而,在实验过程中,NH3通量出现了显著差异。在4龄TM幼虫处理中,各处理间pH、总氮(TN)和ADF差异显著;相反,在咖啡渣和膨润土处理的粪便中,6龄TM幼虫对pH、干物质(DM)、TN、ADF和NDF含量的影响显著高于只处理禽畜粪便。综上所述,在添加咖啡渣和膨润土的禽粪中饲养6龄TM幼虫可以减少堆肥过程中对环境的影响。

India's beekeeping industry primarily revolves around two domesticated honey bee species, Apis cerana and A. mellifera, which are central to commercial beekeeping. In addition, there are four wild honey bee species—A. dorsata, A. laboriosa (sympatric with A. dorsata), A. florea, and A. andreniformis (sympatric with A. florea)—also producing a significant portion of honey. Traditionally, A. cerana was reared in India, but after initial efforts dating back to 1880, the successful introduction of A. mellifera was achieved in 1964. Due to A. cerana's lower honey yield, higher propensity for absconding and swarming, susceptibility to wax moths, and being a low propolizer, A. mellifera gradually replaced it in many regions for commercial beekeeping after 1975. Recognizing the potential of beekeeping for rural development and supported by government initiatives, India has become a leading honey producer. While honey and beeswax production exhibit a growing trend, Indian apiculture remains largely centered on honey production. However, other hive products such as bee pollen, royal jelly, propolis, bee venom, and drone brood as animal feed offer untapped potential. India's rich floral diversity and extensive agro-ecosystems offer immense potential for expanding the beekeeping industry. This calls for a holistic strategy including bee subspecies mapping, sustainable resource management, hive product diversification, disease control, and stakeholder awareness. Additionally, fostering the rearing of other crucial pollinators, such as bumble bees and stingless bees, is essential. By addressing these aspects, Indian apiculture can advance significantly, contributing to sustainable agriculture, rural livelihoods, and environmental conservation.

印度的养蜂业主要围绕着两种家养蜜蜂——印度蜜蜂(Apis cerana)和蜜蜂(A. mellifera),它们是商业养蜂的核心。此外,还有野生蜜蜂a种4种。dorsata, a . laboriosa(与a . dorsata同属),a . florea和a . andreniformis(与a . florea同属)-也生产相当一部分蜂蜜。传统上,蜜蜂是在印度饲养的,但经过1880年的初步努力,1964年成功引进了蜜蜂。由于蜜蜂产蜜量较低,易潜逃和蜂群,易受蜡蛾侵害,且蜂胶含量较低,1975年以后在许多地区逐渐被蜜蜂取代,用于商业养蜂。认识到养蜂对农村发展的潜力,并在政府倡议的支持下,印度已成为领先的蜂蜜生产国。虽然蜂蜜和蜂蜡的生产呈现增长趋势,但印度的养蜂业仍然主要以蜂蜜生产为中心。然而,其他蜂箱产品如蜂花粉、蜂王浆、蜂胶、蜂毒和雄蜂幼虫作为动物饲料提供了尚未开发的潜力。印度丰富的花卉多样性和广泛的农业生态系统为扩大养蜂业提供了巨大的潜力。这需要一个全面的战略,包括蜜蜂亚种制图、可持续资源管理、蜂箱产品多样化、疾病控制和利益相关者意识。此外,培育其他重要的传粉媒介,如大黄蜂和无刺蜜蜂,是必不可少的。通过解决这些问题,印度养蜂业可以取得重大进展,为可持续农业、农村生计和环境保护做出贡献。

The flower bugs, Orius maxidentex Ghauri and Orius minutus (Linnaeus), are important natural enemies of agricultural pests such as thrips and aphids. Insect olfactory systems play an important role in chemical communication, aiding them in locating host or prey habitats. To gain a deeper understanding of the role that sensory organs play in the biological behaviors of these flower bugs, the external structures of antennae and antennal sensilla were demonstrated using scanning electron microscopy (SEM). The antennae of the two species are linear in shape and consist of scape, pedicel, and two flagellomeres. The antennae of O. maxidentex were shorter compared to those of O. minutus. Additionally, the total length of the male antennae was longer than that of the female antennae in both species. Four types and four subtypes of antennal sensilla were documented in both species, including sensilla trichodea (ST I and ST II), sensilla chaetica (SCh I and SCh II), sensilla basiconica (SB), and sensilla campaniformia (SCa). Sexual dimorphism was not observed in the type and distribution of antennal sensilla but existed in the abundance of sensilla basiconica. Our findings provide important insights for future studies on defining the olfactory function of flower bug antennae using electrophysiological methods, especially in the heat-resisting species O. maxidentex.

花蝽(Orius maxidentex gauri)和花蝽(Orius minutus (Linnaeus))是蓟马和蚜虫等农业害虫的重要天敌。昆虫的嗅觉系统在化学通讯中起着重要作用,帮助它们定位寄主或猎物的栖息地。为了更深入地了解感觉器官在这些花虫的生物学行为中所起的作用,利用扫描电子显微镜(SEM)对触角和触角感受器的外部结构进行了研究。两种的触角呈线状,由花苞、花梗和两个鞭毛组成。长柄瓢虫的触角较短。此外,两种雄虫的触角总长度均大于雌虫。在这两个物种中都发现了触角感器的4种类型和4个亚型,包括毛感器(ST I和ST II)、chaetica感器(SCh I和SCh II)、basiconica感器(SB)和campaniformia感器(SCa)。触角感受器的类型和分布不存在性别二态性,但基本感受器的丰度存在性别二态性。我们的研究结果为进一步利用电生理方法定义花蝽触角的嗅觉功能,特别是在耐热物种O. maxidentex中提供了重要的见解。

This study evaluated the insecticidal, repellent, and fumigant activities of four plant-derived extracts: Ficus carica (common fig), Eruca sativa (arugula), Portulaca oleracea (common purslane), and Lupinus albus (white lupin) against adult Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). Gas chromatography–mass spectrometry (GC–MS) analyses identified key bioactive compounds, including unsaturated fatty acids, phytosterols, and tocopherols, which may contribute to their insecticidal and repellent properties. In the residual paper technique, F. carica extract exhibited the highest mortality (22% at 100 mg/mL), followed by E. sativa (14%) and L. albus (6%), while P. oleracea induced only 2% mortality. Repellency bioassays revealed strong deterrent effects, particularly for F. carica and E. sativa. After 3 h, F. carica exhibited 98% repellency at 2 mg/cm2, maintaining 66% at 0.5 mg/cm2 and 56% at 0.125 mg/cm2, indicating broad-spectrum efficacy. E. sativa followed with 64% repellency at 2 mg/cm2, sustaining over 50% repellency across all concentrations. Although repellency declined over time, F. carica retained 70% at 2 mg/cm2 after 24 h, while E. sativa maintained 64% repellency. In contrast, L. albus and P. oleracea exhibited weaker repellency. These findings highlight the strong repellent effects of F. carica and E. sativa, suggesting their potential as natural alternatives to synthetic insecticides in stored grain pest management. Under fumigation conditions, F. carica, E. sativa, and P. oleracea exhibited minimal insecticidal activity, and L. albus had no measurable effect. These results indicate that the primary potential of F. carica and E. sativa lies in their strong repellency and moderate contact toxicity, rather than fumigation.

本研究评价了无花果(无花果)、芝麻菜(芝麻菜)、马齿苋(马齿苋)和白露豆(白露豆)四种植物提取物对黄颡鱼(拟甲)成虫的杀虫、驱避和熏蒸活性。气相色谱-质谱(GC-MS)分析确定了关键的生物活性化合物,包括不饱和脂肪酸、植物甾醇和生育酚,这可能有助于它们的杀虫和驱避特性。残纸技术中,100 mg/mL时,乳香提取物的死亡率最高,为22%,其次是苜蓿(14%)和白花苜蓿(6%),而马齿苋的死亡率仅为2%。驱避生物试验结果显示,对蜱虫和油菜有较强的阻吓作用。3 h后,2 mg/cm2的驱避率为98%,0.5 mg/cm2的驱避率为66%,0.125 mg/cm2的驱避率为56%,具有广谱性。在2 mg/cm2浓度下,苜蓿的驱避率为64%,在所有浓度下均保持50%以上的驱避率。虽然随着时间的推移,驱避力有所下降,但在2 mg/cm2的剂量下,24 h后蜱虫仍保持70%的驱避力,而油菜仍保持64%的驱避力。相比之下,白色乳酸菌和马齿苋的驱避力较弱。这些研究结果突出表明,镰状绦虫和豌豆绦虫具有很强的驱避作用,这表明它们有可能作为合成杀虫剂的天然替代品,用于储粮害虫管理。在熏蒸条件下,carica、E. sativa和P. oleracea表现出最小的杀虫活性,而L. albus没有可测量的杀虫效果。这些结果表明,蜱螨和芥螨的主要潜力在于其强大的驱避力和中等的接触毒性,而不是熏蒸。
