苹果黄蚜是苹果的主要害虫之一。它以成虫和若虫群集加害新稍、嫩芽和叶片,影响光合作用,抑制新稍生长,严重时则能引起早期落叶和树势衰弱。在生产上长期使用氧化乐果对其进行防治,导致其抗性增强,防治效果不佳。据此,我们于1993年在宽城县亮甲台村果园用10％的安绿宝乳油(广东门江市农药厂生产)对黄蚜进行了田间防治试验。 本试验以7年生的短枝红星为试验树。在苹果黄蚜发生盛期、高温、干旱、无雨的7月23日进行如下5个处理:喷施10％的安绿宝
Apple yellow aphid is one of the major pests of apple. It is harmful to adults and nymphs cluster slightly new, shoots and leaves, affecting photosynthesis, inhibit the new growth, in severe cases can cause early deciduous and tree weakness. Long-term use of omethoate in the production of its prevention and control, leading to increased resistance, prevention and control of poor results. Accordingly, we conducted a field control experiment on yellow aphid with 10% An Emerald Cream (produced by Guangdong Jiangmen Pesticide Factory) in Orchard, Liangjiantai Village, Kuancheng County in 1993. In this study, 7-year-old short branch red star as the test tree. Apple yellow aphid occurred in the peak, high temperature, drought, no rain July 23 for the following five treatment: spraying 10% Emerald
