| 摘 要： | 长绵粉蚧在陕西省苹果园1a发生1代,以3龄若虫在树干、大枝粗皮缝隙处结茧越冬.4～5月为主要为害期,出蛰若虫和成虫吸食苹果树枝、叶、果实的汁液,削弱树势.防治上应重点抓好果树开花前越冬若虫出蛰期和6～7月1龄若虫发生期的化学防治;开花期～幼果期应以保护利用天敌为主,尽量避免喷洒化学农药.

| Abstract: | Phenacoccus pergandei Cokerell occurs 1 generations per year in apple orchards of Shaanxi Province. The cocoo of its third-age nymphs overwinters at the trunk, bark crack of branch of apple tree. The main damaging period of Phenacoccus pergandei appears in April-May, the nymphs of hibernating and adults suck in juice of trigs, leaves and fruits of apple tree to weaken growing of the tree. The key time of control the pest is the period of overwintered nymphs before flowering and the occurrence period of the first-age nymphs in June-July, the main method of controlling damage is spraying chemicals. As a principal measure for protection and utilization of natural enemy should be used to avoid spraying pesticides in flowing season-young fruit period. |
