为了经济有效地防治果树害虫,以期降低生产成本,减少农药在果品中的残毒,我们在果园中进行了挂加杨枝把诱杀害虫成虫的试验,已取得初步效果。用杨树枝把诱杀害虫成虫的具体方法是:将加杨枝条采下,晒至半干(叶片凋萎)时,捆成4～6厘米粗的枝把,例挂在果树枝上,每亩5个枝把。每天早晨用塑料袋捕杀枝把中诱集的成虫。捕杀前,先将袋内喷上敌敌畏,然后把口握紧,将枝把套入袋 In order to economically and effectively control pests of fruit trees, in order to reduce production costs and reduce residues of pesticides in fruit, we carried out experiments in the orchards to hang trapped adult pests. The preliminary results have been achieved. The specific method of trapping insect pests with poplar branches is to add Yang shoots to the next, drying to the semi-dry (withered leaves), bundled into 4 to 6 cm thick branches, such as hanging on the branches of fruit trees, mu 5 sticks. Plastic bags are used every morning to trap the adults trapped in the branches. Before killing, the first spray of dichlorvos bag, and then the mouth clenched, the sticks into the bag
