Sequencing and characterizing odorant receptors of the cerambycid beetle Megacyllene caryae

► 57 odorant receptors sequenced from a long horned beetle. ► Highly expressed receptors tested for sensitivity to the beetle's pheromone. ► Three receptors responded to 2-methyl-1-butanol, 2,3-hexanediol, 2-phenylethanol. ► First odorant receptors functionally characterized from a species of beetle.
