Silicon-coated carbon quantum dots composite nanomaterials mediate pest resistance activation in tobacco (Nicotiana tabacum).

Background: Plant resistance inducers based on nanomaterials (NMs) are a cutting-edge and promising field of interdisciplinary research, focused on developing environmentally and ecologically friendly alternatives for protecting crops. Studies have shown that NMs composed of silicon (SiO) and carbon quantum dots (CDs) can help plants better withstand various environmental and pest-related stresses.

Results: We synthesized and characterized SiO-coated CDs (SiO@CDs) NMs that were found to be absorbed by tobacco leaves.

Two new species of larval Erythraeidae (Parasitengona) ectoparasites of leafhoppers from Southwestern China.

In this study, three species were examined. Among them, two new species, and from Southwestern China, were described and illustrated based on larvae. The two new species can be distinguished from the known species by the following characteristics: the anterior sensilla are nude, and the gnathosoma has two pairs of nude hypostomalae in ; the anterior sensilla and posterolateral scutalae are located in the posterior half of the scutum, and the posterior hypostomalae with barbs on the proximal half in In addition, a new host and distribution range of Xu & Jin, 2022 is reported.

Phylogenomics offers new insights into the classification of Phytoseiidae (Acari: Mesostigmata).

Phytoseiid mites are significant natural predators of harmful mites and constitute one of the largest groups within Gamasina (Acari: Mesostigmata). The currently accepted classification divides the Phytoseiidae family into three subfamilies, primarily based on the pattern of their dorsal setae. However, the phylogenetic relationships among these subfamilies remain unresolved.

Redescription of three species of Aponychus from China with ontogenetic development and morphological variations of A. corpuzae (Acariformes: Tetranychidae).

Ontogenetic development of leg chaetotaxy, stylophore and striae of the dorsal integument, and variations of leg setal counts and length of idiosomal setae in Aponychus corpuzae are discussed. The following changes were observed during the ontogenetic development of A. corpuzae: the depth of the depression in stylophore increases; the dorsal striae gradually reduce in number and prominence; the length of dorsal setae sc1, c12, d12 and e1 reduce in size; adult dorsal setae much thicker than those of immature stages.

Notch Signaling in Insect Development: A Simple Pathway with Diverse Functions.

Notch signaling is an evolutionarily conserved pathway which functions between adjacent cells to establish their distinct identities. Despite operating in a simple mechanism, Notch signaling plays remarkably diverse roles in development to regulate cell fate determination, organ growth and tissue patterning. While initially discovered and characterized in the model insect , recent studies across various insect species have revealed the broad involvement of Notch signaling in shaping insect tissues.

Genomics, transcriptomics, and peptidomics of the greater wax moth Galleria mellonella neuropeptides and their expression in response to lead stress.

Neuropeptides are crucial in regulation of a rich variety of developmental, physiological, and behavioral functions throughout the life cycle of insects. Using an integrated approach of multiomics, we identified neuropeptide precursors in the greater wax moth Galleria mellonella, which is a harmful pest of honeybee hives with a worldwide distribution. Here, a total of 63 and 67 neuropeptide precursors were predicted and annotated in the G.

Role of the Hox Genes, , and , in Leg Development of the Spider Mite .

Mites, the second largest arthropod group, exhibit rich phenotypic diversity in the development of appendages (legs). For example, the fourth pair of legs (L4) does not form until the second postembryonic developmental stage, namely the protonymph stage. These leg developmental diversities drive body plan diversity in mites.

Morphological changes and ontogenetic development of Amblyseius eharai Amitai & Swirski (Acari: Phytoseiidae).

This paper describes the immature and mature characteristics of Amblyseius eharai Amitai & Swirski in detail to determine its morphological ontogeny based on laboratory-reared specimens. The main changes during ontogeny are as follows: the pronotal shield extends to j6 level and opisthosoma is unsclerotized in the larva; the dorsum has two shields in the protonymph, pronotal shield slightly expended comparing to that of the larva, and the opisthonotal shield smooth and weakly sclerotized. The podonotal and opisthonotal shields in the deutonymph are partially fused, and the dorsal shield is complete, covering almost the entire opisthonotum in adults in both sexes.
