| Abstract: | "Sex pheromones play an essential role when moths are searching for mates. Male olfactory receptor neurons (ORNs) are the primary determinant during peripheral pheromone recognition. Here, we identified the sex pheromones of a global agricultural pest, Mythimna loreyi, using gas chromatography coupled with mass spectrometry and electroantennographic detection. Nine pheromone components were identified, including (Z)-9-tetradecen-1-yl acetate (Z9-14:OAc), (Z)-7-dodecen-1-yl acetate (Z7-12:OAc), and (Z)-11-hexadecen-1-yl acetate (Z11-16:OAc), and the first two elicited electrophysiological activities in the male antennae. Trichoid sensilla were classified into four functional types on the basis of neuronal responses to pheromones by single sensillum recording. Five functional ORNs were involved in recognizing pheromones and pheromone analogues. Finally, a field bioassay revealed that a blend of Z9-14:OAc, Z7-12:OAc, and Z11-16:OAc at a ratio of 100:8.8:19.7 was highly efficient for trapping males. Our results uncover the pheromone recognition mechanism in M. loreyi and provide a novel angle for developing efficient sex attractants of pests on the basis of screening the peripheral olfactory neurons" |
