    Striking parallels between dorsoventral patterning in Drosophila and Gryllus reveal a complex evolutionary history behind a model gene regulatory network

    Matthias Pechmann et al.
    Crucial functions of Toll signalling during dorsoventral axis formation might have evolved convergently in flies and crickets.

    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.

    Amino acid synthesis loss in parasitoid wasps and other hymenopterans

    Xinhai Ye et al.
    The synthesis capability of some amino acids is lost during the insect evolution, and hymenopteran parasitoids can make up for these deficiencies by altering free amino acid concentrations in host.

    Symbiont-mediated cytoplasmic incompatibility: What have we learned in 50 years?

    J Dylan Shropshire et al.
    This review serves as a gateway to experimental, conceptual, and quantitative themes of cytoplasmic incompatibility (CI) and outlines significant gaps in the understanding of CI's mechanism that are ripe for investigation.

    Apoptotic neurodegeneration in whitefly promotes the spread of TYLCV

    Shifan Wang et al.
    A plant virus, Tomato yellow leaf curl virus, manipulates the host preference of the vector insect whitefly to promote its transmission by inducing caspase-dependent apoptotic neurodegeneration in vector's brain.

    Bacterial contribution to genesis of the novel germ line determinant oskar

    Leo Blondel et al.
    Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.

    Modelling the climatic suitability of Chagas disease vectors on a global scale

    Fanny E Eberhard et al.
    The global ensemble forecasting niche modelling of 11 vector competent triatomine species revealed climatic suitable regions outside their native distribution including the cosmopolitan vector Triatoma rubrofasciata.

    Rarity is a more reliable indicator of land-use impacts on soil invertebrate communities than other diversity metrics

    Andrew Dopheide et al.
    Rarity metrics reveal pervasive negative impacts of agricultural land use on soil invertebrate communities, whereas widely-used richness and diversity metrics underestimate the magnitude of these impacts.

    Disparate expression specificities coded by a shared Hox-C enhancer

    Steve W Miller, James W Posakony
    Tucked within a well-known story of diverging gene function is a single enhancer encoding two inseparable specificities that regulates two adjacent genes, each with different spatiotemporal expression patterns.

    A large genomic insertion containing a duplicated follistatin gene is linked to the pea aphid male wing dimorphism

    Binshuang Li et al.
    The application of long-read sequencing to the pea aphid wing dimorphism system reveals genomic structural divergence as a genetic mechanism of adaptation.
