皱小蠹Scolytus rugulosus Ratzeburg广泛分布于喀什、和田、阿克苏、吐鲁番、乌鲁木齐和伊犁等地的水果产区,是苹果、梨、桃、杏、海棠、樱桃、酸梅、李和扁桃上钻蛀树木而且有毁灭性的害虫。我们于1999—1981年,对其生物学特性和防治进行了研究,总结如下。 一、为害情况 凡是由于树龄老、栽培条件差、管理不善和其他病虫为害等造成长势衰弱的果树都易受害;长势强壮的不易受害或受害较轻。 Scolytus rugulosus Ratzeburg is widely distributed in the fruit producing areas of Kashgar, Wada, Aksu, Turpan, Urumqi and Ili. It is an area of ​​apple, pear, peach, apricot, crabapple, cherry, plum, And there are devastating pests. In 1999-1981 we studied their biological characteristics and their prevention and treatment, and summarized the following. First, the damage situation usually due to old age, poor cultivation conditions, poor management and other pests caused by the growth of weak fruit trees are vulnerable; growing strong less vulnerable or victimized.
