- The attraction of male Neodiprion dailingensis Xiao et Zhou to pheromone substances identified from other Neodiprion species was tested in plantations of Pinus tabulaeformis Carr. in Liaoning Province in north-eastern China. Both the acetate and propionate of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol) were highly attractive. An addition of 10% of the (2S,3R,7R)-isomer did not significantly reduce the catch to the acetate. The (2S,3R,7R)-isomer was not attractive by itself. This is the first pheromone study of a species belonging to the recently described East Asian group of Neodiprion. The response of N. dailingensis males is similar to that of N. sertifer males in eastern part of Asia.
