| Popis: | The newly invasive soybean aphid, Aphis glycines Matsumura, has seriously threatened soybean production in North America, after having spread to 20 states in the United States and several southern provinces of Canada. Control ofA.glycines has focused on applications of insecticides, which are not a long-term solution to soybean aphid pest management. In autumn, soybean aphids start producing alate females (gynoparae) that search for their overwintering host plants, the common buckthorn, Rhamnus cathartica. The gynoparae then produce pheromone-emitting wingless female offspring (oviparae) that attract male aphids. In this study, we report the chemical identiÞcation of the soybean aphid sex pheromone using gas chromatographyÐ electroantennogram, gas chromatog- raphyÐmass spectrometry, and nuclear magnetic resonance spectroscopy. Behavioral activities of males and gynoparous females in the Þeld were also characterized. The potential applications using formulations containing speciÞc soybean aphid pheromone compositions for reducing overwintering populations are discussed. |
