顶梢卷叶蛾分布全国各地,为害苹果、海棠、沙果、山荆子、棒子、柰子、梨,以幼虫卷食新梢尖端嫩叶,危害新梢生长,造成苗木生长不够高度而延迟出圃,使幼树整形受到干扰,使结果树无法形成花芽而导致减产。以2～3龄幼虫在顶梢卷叶里结茧越冬,被害顶梢叶苞枯死经久不落。防治方法:①消灭越冬幼虫和第一代幼虫。冬季,看到顶梢有枯死而叶苞不落的,一律剪除,并集中烧毁或深埋。在生长季节,看到顶梢卷成一团的,用手捏死其中的幼虫。②在虫口密度大的果园,于越冬代幼虫产卵盛期和幼虫孵化盛期喷药,可用90％敌百虫800～1000倍液,或50％辛硫磷1500 Top tip leaf roller distribution throughout the country, the damage apple, Begonia, sand fruit, mountain Jing Zi, corncob, razor clam, pear, larva tip feeding tip, endanger the growth of new shoots, resulting in the growth of seedlings is not high enough to delay the nursery, The saplings are disturbed so that the result tree can not form flower buds and result in reduced production. To 2 ~ 3 instar larvae in the tip of the coiled cocoon wintering, the culprit top leaves bud died forever. Prevention and treatment methods: ① eliminate overwintering larvae and the first generation larvae. Winter, see the top dead withered leaves are not falling, all cut off, and concentrated burned or buried. In the growing season, see the tip into a ball, with their hands to kill the larvae. ② in the population density of orchards, in the winter females larvae spawning peak and the larvae of the peak of spraying, available 90% trichlorfon 800 to 1000 times, or 50% phoxim 1500
