梨小食心虫[Grapholitha molesta(Busck)]在果园中严重危害桃果和梨果等,为了确保好果率,每年皆须连续大量施用各种农药进行防治,但效果并不理想。近年来综合防治受到人们的重视,在防治害虫的新方法和新途径方面展开了各种新的尝试。 在批林批孔运动中,我们认真学习毛主席有关教育革命的教导,批判了林彪、孔老二散布的“上智下愚”
Grapholitha molesta (Busck)] Pests and pears are seriously endangered in orchards. In order to ensure a good fruit rate, a large number of pesticides should be continuously administered in large quantities every year for prevention and treatment, but the results are not satisfactory.

In the campaign to criticize the proletarians and prayers, we conscientiously studied Chairman Mao’s teachings on the education revolution and criticized the “wisdom and wisdom” spread by Lin Piao and Kong Laowu.
