桃小食心虫越冬代成虫的产卵期长达两个多月,幼虫孵化后便蛀入果内为害,给防治带来一定的困难。 1981年以来,许多单位研究应用昆虫病原线虫防治桃小食心虫,并在较大面积上进行了田间示范。从郑州、烟台、泰安、西安、熊岳等地累计2千多亩苹果园施放线虫的结果看:越冬代成虫羽化率、一代卵果率、虫果率都相当于或低于农药处理区。施线虫区的一代卵果 Peach beetle overwintering adult spawning period of up to two months, after larvae hatch into the fruit of the borers, to prevent some of the difficulties. Since 1981, many units have studied the application of entomopathogenic nematodes to control peach moth and conducted field demonstrations over a large area. From Zhengzhou, Yantai, Tai’an, Xi’an, Xiong Yue accumulated more than 2 acres of apple orchards release nematodes results: overwintering generation adult emergence rate, the first generation of egg fruit rate, fruiting rate are equivalent to or lower than the pesticide processing area. Nematode area generation of egg fruit
