The pea aphid, <i>Acyrthosiphon pisum</i>, exhibits higher hemolymph trehalose levels than other insects. However, the dynamics of hemolymph trehalose levels throughout its life stages remain unclear owing to the challenges associated with obtaining hemolymph from these small insects. Therefore, this study was conducted to quantify hemolymph trehalose levels in <i>A</i>. <i>pisum</i> using a fluorescent trehalose sensor (Tre-C04), which enhances green fluorescent protein fluorescence through the binding of trehalose to a ligand-binding protein fused to the fluorophore. Trehalose levels were successfully quantified in minimal hemolymph samples from individual aphids, with measurements spanning from the first nymphal stage to the adult stage in both the winged and wingless forms of <i>A</i>. <i>pisum</i>. Hemolymph trehalose levels remained relatively stable throughout the life cycle but exhibited a gradual increase with each developmental stage. Notably, adult winged aphids exhibited significantly higher hemolymph trehalose levels than wingless aphids. Given that wing morph determination occurs early in the nymphal stage, these findings suggest that hemolymph trehalose levels are regulated post-wing morph development. Further investigation of the expression of genes associated with trehalose metabolism revealed that trehalose phosphate synthase 2 levels were downregulated in early-stage wingless adults, whereas insulin-related peptide 5 levels were upregulated in wingless aphids.

Aquaporins play a key role in this process by facilitating the rapid transport of water molecules across cell membranes, maintaining cellular water balance, and adapting to changes in external salinity. In this study, I investigate the genetic diversity and expression levels of aquaporins in Elateroidea, particularly focusing on the Lampyridae family, using transcriptomic data and in silico analyses. The results reveal the diversity of aquaporins and compare gene expression patterns between freshwater aquatic Lampyridae and terrestrial Elateroidea species, such as Lycidae, Phengodidae, and Elateridae. Phylogenetic analyses identify seven distinct clades of aquaporins and uncovered gene duplication events related to the diversification of Elateridae and Lampyridae. A comparative abundance analysis indicated higher aquaporin expression in aquatic fireflies, aligning with the need for efficient osmoregulation in aquatic environments. Additionally, stage-specific expression patterns in <i>Aspisoma lineatum</i> (Neotropical firefly) and <i>Aquatica lateralis</i> (Paleartic firefly) suggest species-specific strategies for coping with osmotic challenges during development.

To explore the underlying mechanisms of Se impact, the dynamin gene was knocked down by injecting siRNAs (<i>Dynamin-1</i>, <i>Dynamin-2</i>, and <i>Dynamin-3</i>). This was followed by an analysis of the target gene and levels of silk protein genes, as well as growth and developmental indices, Se-enrichment capacity, degree of oxidative damage, and antioxidant capacity of <i>B. mori</i>. Our findings showed a considerable decrease in the relative expression of the dynamin gene in all tissues 24 h after the interference and a dramatic decrease in the silkworm body after 48 h. RNAi <i>dynamin</i> gene decreased the silkworm body weight, cocoon shell weight, and the ratio of cocoon. In the meantime, malondialdehyde level increased and glutathione level and superoxide dismutase/catalase activities decreased. 50 μM Se markedly ameliorated these growth and physiological deficits as well as decreases in dynamin gene expression. On the other hand, there were no significant effects on fertility (including produced eggs and laid eggs) between the interference and Se treatments.

The <i>dynamin</i> gene was highly expressed in the silk gland and declined significantly after interference.

The intracellular localization of HiRNASET2 in lysosomes of plasmatocytes, its extracellular association with bacteria, and the presence of a putative antimicrobial domain in the molecule, suggest its potential role in RNA clean-up and as an alarm molecule promoting phagocytosis activation by hemocytes.
