摘要:
The Vespidae is a diverse family of wasps and hornets that are formidable predators of insects, including social  bees1 , and includes a number of  invasive species2 . Recently, the world’s largest hornet, Vespa mandarinia Smith (Hymenoptera: Vespidae), which occurs naturally in the Indomalayan region, has been found in Canada and the United States2 . Some simulations indicate that it could rapidly spread throughout Washington and Oregon in the western US, as well as some eastern parts of the country2,3, threaten native bees and honeybees, and harm bee-pollinated crop production worth over $100 million annually3 . There is consequently an urgent need to learn more about V. mandarinia’s reproductive biology and to develop trapping methods to locate its nests and to control its reproduction. We identififi ed V. mandarinia queen produced sex pheromone from the 5th and 6th intersegmental sternal glands of virgin queens. The major active compounds were hexanoic acid, octanoic acid, and decanoic acid. When placed in fifi eld traps, the synthetic compounds and a queenequivalent mixture rapidly attracted hundreds of males but no females or other species.
