    The neuropeptide tachykinin is essential for pheromone detection in a gustatory neural circuit

    Shruti Shankar et al.
    The cellular and molecular substrates that underlie the programmed behavioral response to a gustatory sex pheromone have been identified.

    An insect anti-antiaphrodisiac

    Colin S Brent et al.
    The first evidence is presented of a compound released by mated females that directly counteracts the effects of a seminal anti-aphrodisiac, but has no attractant properties in itself.

    Sex-determining genes distinctly regulate courtship capability and target preference via sexually dimorphic neurons

    Kenichi Ishii et al.
    Sex-specific characteristics of the fruit fly courtship behavior are not specified by a single binary switch, but as a combination of traits that are modularly specified by separable genetic switches.

    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.

    Sex-specific triacylglycerides are widely conserved in Drosophila and mediate mating behavior

    Jacqueline SR Chin et al.
    Triacylglycerides found in the males of 11 species of Drosophila form a largely overlooked, novel, sex-specific class of pheromones that act to suppress courtship behaviour.

    miR-124 controls male reproductive success in Drosophila

    Ruifen Weng et al.
    A small RNA molecule called miR-124 controls pheromone production and sexual behaviour in Drosophila by regulating sex-specific gene expression in males.
  1. Episode 41: September 2017

    In this episode we hear about biomarkers for epilepsy, how fish can recognise faces, insect anti-anti aphrodisiacs, and why striving for novelty may hinder the progress of science.

    Regulation of sleep homeostasis by sexual arousal

    Esteban J Beckwith et al.
    Sexual arousal, exposure to aphrodisiac pheromones, or mere activation of peripheral pheromone-sensing neurons can modulate sleep homeostasis and are able to counteract the effects of sleep deprivation in Drosophila.
