Galleria mellonella (greater wax moth) larvae are used widely as surrogate infectious disease models, due to ease of use and the presence an innate immune system functionally similar that vertebrates. Here, we review G. mellonella-human intracellular bacteria pathogen infection models from genera Burkholderia, Coxiella, Francisella, Listeria, Mycobacterium. For all genera, has increased understanding host-bacterial interactive biology, particularly through studies comparing virulence closely related species and/or wild-type versus mutant pairs. In many cases, in mirrors found mammalian although it is unclear whether pathogenic mechanisms same. The speeded up vivo efficacy toxicity testing novel antimicrobials treat infections caused by bacteria: area will expand since FDA no longer requires animal for licensure. Further mellonella-intracellular be driven advances genetics, imaging, metabolomics, proteomics, transcriptomic methodologies, alongside development accessibility reagents quantify markers, which underpinned a fully annotated genome.

The relationship between insect pathogenic fungi and their hosts is a classic example of co-evolutionary arms race pathogen target host: parasites evolve towards mechanisms that increase advantage over the host, host increasingly strengthens its defenses. present review summarizes literature data describing direct indirect role lipids as an important defense mechanism during fungal infection. Insect comprise anatomical physiological barriers, cellular humoral response mechanisms. entomopathogenic have unique ability to digest cuticle by producing hydrolytic enzymes with chitin-, lipo- proteolytic activity; besides oral tract, pays way for entry within host. key factor in resistance infection presence certain types (free fatty acids, waxes or hydrocarbons) which can promote inhibit attachment cuticle, might also antifungal activity.

Bee populations are exposed to multiple stressors, including land-use change, biological invasions, climate and pesticide exposure, that may interact synergistically. We analyze the combined effects of warming sublethal insecticide exposure in solitary bee Osmia cornuta. Previous studies show warm wintering temperatures cause body weight loss, lipid consumption, fat depletion. Because plays a key role xenobiotic detoxification, we expected bees scenarios would be more sensitive pesticides. O. cornuta females three treatments: current scenario (2007-2012 temperatures), near-future (2021-2050 projected distant-future (2051-2080). Upon emergence spring, were orally doses an (Closer, a.i. sulfoxaflor; 0, 4.55 11.64 ng a.i./bee). measured on phototactic response, syrup longevity. Wintering treatment by itself did not affect winter mortality, but loss increased with increasing temperatures. Similarly, hardly influenced response or consumption. However, wintered at warmest had shorter longevity, strong fecundity predictor Osmia. Insecticide especially high dose, impaired ability respond light, resulted reduced consumption The combination dose 70% longevity decrease. Smaller bees, resulting from smaller pollen-nectar provisions, suggesting nutritional stress further compromise Our results synergistic interaction between two major drivers declines, indicate will become pesticides under global scenario. findings have important implications for regulation underscore need consider stressors understand declines.

Thermal condition affects the development and growth of ectotherms. The stenothermic honeybee brood, particularly prepupae, are sensitive to low rearing temperature. fat body plays important roles in energy reserve metabolism during brood development. To date, metabolic changes prepupae responding cold stress have not been completely understood. In this study, ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS)-based non-target metabolome was analyzed between cold-treated (CT, 20 °C, 36 h) control (CK, 35 °C) prepupal honeybees. metabolomic data showed that levels 1860 254 metabolites were significantly increased decreased, respectively, cold-stressed prepupae. These altered metabolites, glutamine, glutamic acid, pyroglutamic oxidized glutathione, enriched into glutamine glutathione pathways. Furthermore, expression metabolism-related genes, glutaminase (GLS), glutamate dehydrogenase (GDH), gamma-glutamyl transferase (GGT-1 GGT-7), decreased cold-exposed compared groups.

Abstract BACKGROUND The fall armyworm (FAW), Spodoptera frugiperda is a notorious invasive pest that poses serious threat to global agricultural production and food security. In China, Cotesia ruficrus has emerged as promising indigenous biological control agent for controlling FAW populations. this study, we conducted series of comprehensive experiments explore the effects C. parasitization on development nutrient metabolism larvae. RESULTS Parasitization by significantly inhibited larvae, reduced their intake more than 60%. Furthermore, concentrations carbohydrate triglyceride increased from third fifth day seventh after parasitization, respectively. However, both levels subsequently decreased during later stages. Transcriptome analysis showed there were 2096 differentially expressed genes (DEGs) between parasitized non‐parasitized These DEGs found be primarily enriched in pathways related immune response, detoxification, lipid synthesis metabolism, protein metabolism. CONCLUSION Taken together, these results strongly indicate ability modulate ultimately benefiting successful parasitoid offspring. findings contribute our understanding intricate interactions host insects natural enemies provide valuable insights into sustainable effective strategies control. © 2025 Society Chemical Industry.

Most insects exhibit high reproductive capacity, which demands large amounts of energy, including macronutrients and micronutrients. Interestingly, many proteins involved in oogenesis depend on metals ions, particular iron (Fe), zinc (Zn), copper (Cu). Mechanisms by metal ions influence reproduction have been described Drosophila melanogaster, but remain poorly understood hematophagous where blood meals include significant ingestion ions. Moreover, there is evidence that some immunity could dual function both processes. This review highlights the importance non-hematophagous insects. In addition, we discuss how optimize physiological processes using crosstalk between physiology immunity, a double-edge sword allocating their functions to protect insect ensure reproduction.
