苹果小卷叶蛾Adoxophyes orana Fischer vonRoslerstamm是我国北方苹果产区的一种重要害虫,除为害苹果外,还为害桃、梨、李、杏、山楂等果树。对卷叶蛾类害虫的防冶,以往偏重于用有机氯或有机磷等药剂防治,虽有较好的防治效果,但这类药剂对苹果园另一类重要害虫——叶螨基本无效,相反,对叶螨的天敌杀伤很大,如果使用不当,往往导致叶螨猖獗为害。1975年陕西省果树研究所曾进行过苹果小卷叶蛾等性激素粗提物的试验,1977年使用人工合成苹果小卷叶蛾性诱剂在苹果园内进行了田间试验,现将结果整理如下。
Adoxophyes orana Fischer vonRoslerstamm is an important pest in the apple producing area in northern China. In addition to apples, peach, pear, plum, apricot, hawthorn and other fruit trees are also harmed. Leaf roller moth pest prevention and treatment, in the past emphasis on the use of organic chlorine or organophosphate and other agents control, although a better control effect, but these kinds of agents on apple orchard another important pest - spider mites basically ineffective, on the contrary, Natural enemies of spider mite damage, if used improperly, often lead to spider mite rampant. 1975 Shaanxi Province Institute of fruit has been carried out apple small leaf roller and other sex hormones crude extract test in 1977 using synthetic apple leaf roller moth sex attractant in the apple orchard in field trials, the results are summarized below.
