    Protein feeding mediates sex pheromone biosynthesis in an insect

    Shiyu Gui, Boaz Yuval ... Daifeng Cheng
    Protein feeding stimulates the production of sex pheromones and promotes fly mating in Bactrocera dorsalis.

    Inversion of pheromone preference optimizes foraging in C. elegans

    Martina Dal Bello, Alfonso Pérez-Escudero ... Jeff Gore
    Worms' attraction to pheromones turns into repulsion when a food patch is depleted, helping them avoid already exploited territories and search for new food sources.

    A host beetle pheromone regulates development and behavior in the nematode Pristionchus pacificus

    Jessica K Cinkornpumin, Dona R Wisidagama ... Ray L Hong
    A lipid-binding protein mediates both attraction and hypersensitivity to a beetle sex pheromone in a specific type of nematode-insect relationship known as necromeny.

    Mating and male pheromone kill Caenorhabditis males through distinct mechanisms

    Cheng Shi, Alexi M Runnels, Coleen T Murphy
    Male C. elegans die through two distinct mechanisms – mating-induced germline activation, and potent male pheromone toxicity – but the latter is unique to males of androdioecious species (made up of hermaphrodites and males).
    1. Neuroscience

    Integrated action of pheromone signals in promoting courtship behavior in male mice

    Sachiko Haga-Yamanaka, Limei Ma ... C Ron Yu
    Identification of two classes of mouse vomeronasal receptors for female pheromone cues suggests distinct gating mechanisms in pheromone-triggered reproductive behaviors.

    Evolved differences in larval social behavior mediated by novel pheromones

    Joshua D Mast, Consuelo M De Moraes ... David L Stern
    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.
    1. Neuroscience

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

    Chun-Chieh Lin, Katharine A Prokop-Prigge ... Christopher J Potter
    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.
    1. Neuroscience

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

    Shruti Shankar, Jia Yi Chua ... Joanne Y Yew
    The cellular and molecular substrates that underlie the programmed behavioral response to a gustatory sex pheromone have been identified.
    1. Neuroscience

    Male pheromones modulate synaptic transmission at the C. elegans neuromuscular junction in a sexually dimorphic manner

    Kang-Ying Qian, Wan-Xin Zeng ... Xia-Jing Tong
    Male pheromone environment increases the cholinergic synaptic transmission at the neuromuscular junction in Caenorhabditis elegans hermaphrodites during development, decreasing hermaphrodites' locomotion activity and promoting mating efficiency.

    Aggregation pheromone 4-vinylanisole promotes the synchrony of sexual maturation in female locusts

    Dafeng Chen, Li Hou ... Xianhui Wang
    4-Vinylanisole acts as maturation-accelerating pheromone to synchronize oocyte maturation of female adults in locusts.
