    Stepwise wiring of the Drosophila olfactory map requires specific Plexin B levels

    Jiefu Li et al.
    PlexB plays a multifaceted role in instructing the assembly of the Drosophila olfactory circuit through temporally-regulated expression patterns and expression level-dependent effects.

    Alcohol potentiates a pheromone signal in flies

    Annie Park et al.
    For Drosophila melanogaster, the scent of alcohol—normally associated with preferred egg-laying sites—potentiates a male pheromone signal, thereby increasing the aggressive competition between males for the reproductive resource.

    Phagocytic glia are obligatory intermediates in transmission of mutant huntingtin aggregates across neuronal synapses

    Kirby M Donnelly et al.
    Prion-like transfer of mutant huntingtin aggregates from presynaptic to postsynaptic neurons is enhanced by neuronal silencing and requires passage through the cytoplasm of Draper-expressing phagocytic glia in adult Drosophila brains.

    Food odors trigger Drosophila males to deposit a pheromone that guides aggregation and female oviposition decisions

    Chun-Chieh Lin et al.
    The activation of Drosophila Or7a receptors guides aggregation and egg-laying behaviors towards both green leaf volatiles and a male-specific food-odor-induced pheromone.

    Regulation of starvation-induced hyperactivity by insulin and glucagon signaling in adult Drosophila

    Yue Yu et al.
    Two functionally antagonizing groups of hormones directly regulate starvation-induced increase in locomotion via a common neural target in fruit flies.

    A novel lineage of candidate pheromone receptors for sex communication in moths

    Lucie Bastin-Héline et al.
    In moths, male receptors tuned to type I female pheromones may not have a monophyletic origin.

    Organization and function of Drosophila odorant binding proteins

    Nikki K Larter et al.
    A genetic analysis reveals that some olfactory sensilla of Drosophila do not require an abundant odorant binding protein and that one such protein may act in gain control.

    The origin of the odorant receptor gene family in insects

    Philipp Brand et al.
    The insect odorant receptor gene family evolved at the base of the class Insecta before the evolution of flight and perhaps as an adaptation to terrestriality, and was therefore an important evolutionary novelty for insects.

    Presynaptic LRP4 promotes synapse number and function of excitatory CNS neurons

    Timothy J Mosca et al.
    The cell surface receptor LRP4, long recognized for postsynaptic functions, also plays a role as a presynaptic determinant of synapse formation by functioning through a downstream kinase pathway.

    Evolved differences in larval social behavior mediated by novel pheromones

    Joshua D Mast et al.
    A novel pheromone/receptor neuron pair mediates attraction between Drosophila larvae, and evolved differences in pheromone signaling underlie changes in social behavior between drosophilid species.
