豫西地区果树桃球蚧防治效果研究

Study on the Control Effect of Fruit Tree Peaches in Western Henan

本研究的目的是为生产防治果树桃球蚧提供技术支撑。研究结果表明,果树桃球蚧在豫西地区每年发生1代,多以二龄若虫在枝条上、干皮缝里越冬,少数以若虫裸体越冬。该虫为害多种果树,以杏树、桃树受害最重。防治桃球蚧最佳适期应为孵化盛期至分泌蜡丝之前;保护果园黑缘红瓢虫可有效控制桃球蚧的发生危害,药剂防治以0.6%苦参碱水剂600倍液为好。

The results of the study showed that the fruit of fruit tree peaches was generations 1 per year in the western Henan Province,with two nymphs overwintering in the branches and seams of the dry skin,and a few nymphs overwintering in nude.The red beetle beetle on the orchard can effectively control the occurrence and damage of peach scale insects.The chemical control is better than 0.6% times of matrine 600 times.
