摘要
研究表明，桃粉蚜一年发生２０～２５代，以卵在桃树枝条的芽腋或树皮裂缝处越冬。越冬卵３月下旬～４月上旬孵化，５月下旬产生有翅蚜迁飞到夏寄主上繁殖，秋季从夏寄主迁回桃树上，１１月产卵在桃树上越冬。桃粉蚜的适温范围为１５～２８℃。测定５种药剂的药效，以氧化乐果、辟蚜雾、甲甲磷为好，应交替使用。
The study indicates that Hyaloptera Amygdali reproducts 20～25 generations a year. It stays in the cracks of the tree peel in winter with eggs. The eggs incubate in the late March to April and then into aphids with wings in the late May to fly to summer host. In the early November, they lay eggs in the peach trees. Of the test effect of five drugs, among them, Omethoate and Pirimor are the best. but they must be used alternafely to prevent drug resistance from occuring.
