近几年苹果瘤蚜在北京西山农场果园的发生呈上升趋势。1991年对几种防治瘤蚜药剂进行了防治时期和防治效果的对比试验。试验在本场果四队30年生金冠树上进行。单株小区,3次重复。试验共设6个处理:(1)50％抗蚜威(国产)2000倍液;(2)50％辟蚜雾(英国产)2000倍液;(3)20％甲氰菊酯(灭扫利)2000倍液;(4)5％顺式氰戊菊酯(来福灵)3000倍液;(5)40％氧乐果1000倍液,(6)空白对照。喷药时间第1次在4月8日(花序露出期),即在其越冬卵孵化初盛期进行;第2次在5月16日(春梢生长期),即在瘤蚜为害高峰前、部分叶片呈现卷叶时进行;第3次在5月27日(春梢生长末期),即在其为害高峰期、瘤蚜全部卷叶时进行;第4次在6月4日(春梢停长期),即在瘤蚜为害严重期、叶片极度纵卷、虫体发红、开始长出翅基、部分叶片的瘤蚜分泌物上出 In recent years apple aphid in Beijing Xishan farm orchard was on the rise. In 1991, several prevention and treatment of lepidopteran antitumor agents were compared with the control period and the control effect. Test in the field fruit four team 30-year-old Golden Crown tree. Single plant, 3 replicates. A total of six treatments were tested in the experiment: (1) 2000 times of 50% pirimicarb (domestic); (2) 2000 times of 50% Lee) 2000 times the liquid; (4) 5% cis-fenvalerate (Fufang Ling) 3000 times; (5) 40% omethoate 1000 times, (6) blank control. The first spraying time was on April 8 (inflorescence exposure period), that is, at the beginning of its overwintering egg hatching stage; the second time was on May 16 (spring shoot growth period), that is, before the phylloxera peak , Some of the leaves appear when the rolling leaves; the third in the May 27 (the spring end of growth), that is, the peak of its damage, the anemia aphid roll all the time; the fourth in the June 4 (spring shoot Stop long-term), that serious damage in the phylloxera period, the leaves of the extreme volume, red worms, began to grow wing-based, part of the leaf aphids secretions on the
