In recent years, serious occurrence occurred in our county apple tree. The victim fruit began to gel, which in turn emits a large amount of brown worm excrement outside the wormhole to adhere to the surface of the wormhole. According to the 1983 survey, the general fruit rate of 20 to 30%, in severe cases up to 70%. To this end, we 1983 ~ 1986, with the Chinese Academy of Sciences Institute of Zoology of the moth borer sex attractant as a reporting tool for the growth and decline of the adult were observed more systematic observation of the initial master of the apple in our county garden
