    Expansion of the fatty acyl reductase gene family shaped pheromone communication in Hymenoptera

    Michal Tupec et al.
    A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.

    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.

    Adaptive substitutions underlying cardiac glycoside insensitivity in insects exhibit epistasis in vivo

    Andrew M Taverner et al.
    Genome engineering and phenotyping in vivo reveal surprising new features of adaptive amino acid substitutions that were previously inaccessible.

    An insect-like mushroom body in a crustacean brain

    Gabriella Hannah Wolff et al.
    An insect-like mushroom body in one group of crustaceans, the mantis shrimps (Stomatopoda), suggests either an ancient origin of this center and its reduction and loss in other crustaceans, or an extraordinary example of convergent evolution with the insect mushroom body.

    A gene horizontally transferred from bacteria protects arthropods from host plant cyanide poisoning

    Nicky Wybouw et al.
    The enzyme that allows some mites and insects to detoxify the hydrogen cyanide produced by plants has been identified.

    Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors

    Roberto A Keller et al.
    Body shape and behavioural specializations found across the castes of ant species evolved together and reflect different abilities for ground behaviors.

    Destructive disinfection of infected brood prevents systemic disease spread in ant colonies

    Christopher D Pull et al.
    Upon detecting a fatal infection using chemical cues, ants puncture the cuticle of sick brood and inject antimicrobial poison that disrupts the pathogen's life cycle and prevents it from reproducing, thus protecting the colony from disease.

    Dual mode of embryonic development is highlighted by expression and function of Nasonia pair-rule genes

    Miriam I Rosenberg et al.
    Pair-rule genes in the wasp Nasonia function as in Drosophila in patterning anterior segments, and similar to ancestral insects in patterning posterior segments, illustrating a mixed-mode transition state between short and long germ embryogenesis.

    The evolution of non-reproductive workers in insect colonies with haplodiploid genetics

    Jason W Olejarz et al.
    A mathematical model predicts the precise conditions for natural selection to favor the evolution of non-reproductive workers in insect colonies with haplodiploid genetics.
