Traditional pest identification mainly relies on manual inspection by experts with specialized knowledge, which is subjective, time-consuming, and labor-intensive. To address these issues, this experiment proposes an improved convolutional neural network (CNN) for accurate identification of 17 types of goji berry pests. Firstly, the original data set is augmented using a multi-graph-occlusion data augmentation method. Subsequently, the augmented data set is imported into the improved CNN for training. Based on the original ResNet18 model, a new CNN, named GojiNet, is constructed by embedding multi-attention fusion modules at appropriate locations. Experimental results demonstrate that GojiNet achieves an average recognition accuracy of 95.35%, representing a 2.60% improvement over the ResNet18 network. Notably, compared to the original network, the training time of this model increases only slightly, while its size is reduced, and the recognition accuracy is enhanced. The experiment verifies the performance of the GojiNet model through a series of evaluation indicators.

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.

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.

Although transcription of the four tektins was predominantly in the testis, knockdown had negligible effects on either sperm abundance or male fertility.

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.

Notably, when maternal or paternal-primed moths were mated to produce the F1 generation, the F1 generation larvae from both primed groups were more resistant to the BmNPV challenge than silkworm larvae with only maternal or paternal priming. 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.
