The midgut water flux model of Tenebrio molitor (T. molitor) is revisited and supported by in vivo experiments. Sequences from proteins putatively involved in water transport were retrieved from the T. molitor transcriptome by Blast and analyzed using bioinformatics tools. Gene expression of selected proteins was determined in three midgut sections (anterior, AM; middle, MM; posterior, PM) by RNA-seq, and transporter proteins were verified in microvillar-membrane-enriched midgut samples by proteomics. Genes encoding three cation chloride cotransporters (CCC) and four aquaporins were expressed in the midgut. TmNaCCC2, TmPrip, and TmEglp1 showed higher expression in the front half, while TmKCC, TmNKCC1, TmDrip, and TmEglp2 were more highly expressed in the back half. However, only TmNaCCC2 was found by proteomics. Midgut water fluxes were quantified by feeding T. molitor larvae with nonabsorbable dye and measuring its concentration along the midgut. The results suggest water absorption in AM and secretion in MM and PM, potentially caused by TmNaCCC2 and TmPrip in AM, and TmKCC and TmDrip in PM, whereas MM serves as a transition region.

Genetic-based strategies that target male fertiliy are currently being evaluated for population suppression. However, a lack of candidate gene targets with appropriate function, specifically in non-model species like L. hesperus, has hindered progress in the development and application of such approaches. Given their conserved role in stabilization of the flagella axoneme and association with sperm motility in many organisms, members of the tektin gene family represent logical targets for genetic-based sterilization. Here, we identified four homologs of the non-vertebrate tektin family from L. hesperus and used RNA interference-mediated knockdown to assess their roles in male fertility. Although transcription of the four tektins was predominantly in the testis, knockdown had negligible effects on either sperm abundance or male fertility.

Phylogenetically, beetles belong to the order Coleoptera, the most species-rich of the Insecta. Coleoptera is divided into four suborders: Polyphaga, Adephaga, Archostemata, and Myxophaga. Specimens from the latter two are difficult to obtain, hence, we have focused our research into the adipokinetic hormone (AKH) peptide family on the former two suborders. Data on the Adephaga were concluded in 2017. The “core Polyphaga” consists of three series: Elateriformia, Staphyliniformia, and Cucujiformia; the latter was concluded in 2019. Here, we report on the AKH sequence(s) of 23 species of beetles from 4 families of Elateriformia, namely, the Buprestidae, Cantharidae, Elateridae, and Lampyridae; and 4 families of Staphyliniformia, namely, the Hydrophilidae, Silphidae, Lucanidae, and Scarabaeidae. Sequence elucidation by mass spectrometry or Edman degradation revealed 13 octapeptides: 5 are novel, 12 are beetle-specific and Schgr-AKH-II is produced in the basal Polyphaga (Elateriformia, in Hydrophilididae and Silphidae). Since Schgr-AKH-II is also found in Adephaga, this confirms the ancestral AKH of Coleoptera. The first change in sequence is recorded in Staphylinoidea with two different residues, notably, the switch from Phe4 to Tyr4. Duplication of AKH peptides is first seen in Lucanidae, as well as the appearance of atypical AKH sequences, such as Phe2, Met4, Leu4, or Phe7 encountered in the Scarabaeoidea. The vast majority of the pest beetles do not have beetle-specific AKHs or share the same AKH as nonharmful beetles.

Importantly, both maternal and paternal contributions to offspring immunity were essential for TGIP. However, due to the characteristics of the BmNPV itself, no within-generation immune responses were detected following BmNPV priming.
