苹果卷叶蛾是苹果树主要害虫之一,它不但为害严重,而且蔓延很快。朝阳县波罗赤公社康家屯大队,1970年产苹果40万斤,苹果卷叶蛾虫果就有10万多斤,虫果占25%。这个大队1977年每株苹果树平均有卷叶虫21头,78年就上升到56头。仅朝阳县每年大约有一千吨苹果被苹果卷叶虫为害,损失20多万元,所以苹果卷叶虫是朝阳地区苹果树的重要防治对象。
Apple leaf roller is one of the major apple pests, not only detrimental, but also spread rapidly. Chaoyang County Balochi commune Kangjiatun brigade, produced 40 million pounds of apples in 1970, apple roll leaf moths have more than 100,000 kilograms of fruit, insect fruit accounted for 25%. In 1977, the brigade had an average of 21 leaf roller worms per plant and increased to 56 heads in 78 years. Only about one thousand tons of apples in Chaoyang County are apprehended by apple leaf-winters each year, with a loss of more than 200,000 yuan. Therefore apple-leaf roller is an important control object for apple trees in the Chaoyang area.
