顶梢卷叶虫(Spilonota lechriaspis Mey.)是我国苹果产区普遍发生的害虫,在河南、江苏、安徽等省黄河故道砂荒地区新发展的果园中,为害相当严重,无论结果树、幼树、苗木均遭害,尤以幼树受害最重。1959年仪封园艺场的苹果幼树,春梢受害一般在50％左右,秋梢则达90％以上。此虫还为害海棠、沙果、梨和杜梨等。它主要为害果树新梢,把顶梢卷成一团,并取食卷梢上的嫩叶和幼芽,因此,对幼树的树冠形成、提早结果和对苗木的快速生长、提早出圃,都能造成不良影响。 作者于1959年在河南兰考地区,对此虫进行了初步研究,本文着重报导该虫在这一苹果栽培新区的生活史、习性;对现行人工防治措施的效果签定,并通过药剂试验明确了对硫磷、敌百虫、DDT等药剂为该虫的有效药剂,同时对其防治上的问题也进行了分析讨 Spilonota lechriaspis Mey. Is a common pest in apple producing areas in China. In the newly developed orchards of sand wasteland in the old course of the Yellow River in Henan, Jiangsu and Anhui provinces, the damage is quite serious. No matter the result tree, young tree , Seedlings were victims, especially young trees hardest hit. In 1959, the apple seedlings in the field of gardening were collected. The damage of spring shoots was about 50% and the autumn shoots reached more than 90%. This insect also damage Begonia, sand fruit, pear and pear and so on. It mainly affects the shoots of fruit trees, curling the tops into a mass, and feeding the young leaves and young shoots on the shoots. Therefore, crown formation, early results and rapid growth of seedlings can be promoted early Cause adverse effects. The author conducted a preliminary study of the pest in Lancang region of Henan in 1959. This article focuses on the life history and habits of the pest in this apple-growing new area. The effect of the current artificial prevention and control measures was signed and the drug test was made clear Parathion, trichlorfon, DDT and other agents for the effective insecticide, also on the prevention and control of the problems were also analyzed
