    Three-dimensional reconstruction of a whole insect reveals its phloem sap-sucking mechanism at nano-resolution

    Xin-Qiu Wang et al.
    3D reconstruction for an insect provides new internal structures at nanometer resolution, and the reconstructed feeding insect reveals unexpected contraction of stylet protractors and suggested a novel phloem sap-sucking model.

    Evolution of insect olfactory receptors

    Christine Missbach et al.
    Insect specific olfactory receptors are not an adaptation to a terrestrial insect lifestyle, but evolved later in insect evolution.
    1. Neuroscience

    A unified platform to manage, share, and archive morphological and functional data in insect neuroscience

    Stanley Heinze et al.
    The InsectBrain Database is a novel, freely available software tool designed to accelerate research in the field of insect neuroscience and to improve implementation of open data concepts.

    The extraembryonic serosa is a frontier epithelium providing the insect egg with a full-range innate immune response

    Chris G C Jacobs et al.
    Contrary to the current perception, insect eggs are very capable of defending themselves against pathogens.

    Serotonin modulates insect hemocyte phagocytosis via two different serotonin receptors

    Yi-xiang Qi et al.
    Insects use serotonin signaling in blood cells to help defend themselves against pathogens.

    Exosomes mediate horizontal transmission of viral pathogens from insect vectors to plant phloem

    Qian Chen et al.
    An important rice reovirus hijacks exosomes to traverse the apical plasmalemma into saliva-stored cavities in the salivary glands of insect vectors, facilitating viral horizontal transmission into rice phloem.

    A putative origin of the insect chemosensory receptor superfamily in the last common eukaryotic ancestor

    Richard Benton et al.
    Comparative genomics and three-dimensional protein modelling identify homologs of insect chemosensory receptors in unicellular eukaryotes and plants.

    Rapid spread of a densovirus in a major crop pest following wide-scale adoption of Bt-cotton in China

    Yutao Xiao et al.
    Exposure to Bacillus thuringiensis (Bt) selects for beneficial interactions between the target insect pest (Helicoverpa armigera) and its symbiotic densovirus that enhances its performance on Bt-crops under field conditions.

    Brood care in a 100-million-year-old scale insect

    Bo Wang et al.
    The discovery of the earliest direct evidence of brood care in insects demonstrates a remarkably conserved egg-brooding reproductive strategy within scale insects in stasis for nearly 100 million years.

    Volatile DMNT directly protects plants against Plutella xylostella by disrupting the peritrophic matrix barrier in insect midgut

    Chen Chen et al.
    The natural volatile component DMNT protects plants from insect attacks by damaging peritropic matrix barriers in insect midguts, paving a promising way for the molecular breeding of plant protection.
