为了寻找桃小食心虫有效的生物防治办法,我们从1984年首先在我省引进了新线虫。1985年至1987年先后与郑州果树研究所,中国农科院生防室协作,在陕西眉县开展了利用新线虫防治苹果桃小食心虫试验研究,从室内保种、繁殖、感染寄主试验到田间应用试验进行了一系列工作。 In order to find an effective biological control method for peach moth, we first introduced nematodes in our province from 1984. From 1985 to 1987, it cooperated with Zhengzhou Fruit Tree Research Institute and Chinese Academy of Agricultural Science and Technology, and conducted research on the prevention and control of apple peach moth using new nematode in Mei County, Shaanxi Province. From the experiments of inbreeding, breeding and host infection in the field, Application experiments conducted a series of work.
