摘要
1985～1991年干山东乳山、福山、栖霞、高密、诸城等地对苹果园主要害虫及其综合防治进行了研究。明确了:1.山东省苹果害虫的现状,种群分布,发生特点,趋势,优势种和天敌种类;2.桃小食心虫发生规律及其与环境的关系;3.山楂叶螨与苹果全爪螨种群数量变化;4.绿盲蝽在果园中的发生与危害状况;5.苹果园害虫综合防治实施方案。两个示范园300余亩的验收结果表明,全年施药6次,其中杀虫剂4次,较常规防治减少用药2～3次,虫病果率低于1％,保叶率85％以上。
During 1985～1991, systymatic investigation and IPM on apple main insect pests were conducted in Rushan, Fushan, Qixia, Gaomi, Zhucheng and Zhaoyuan county, Shandong province. Its major results were composite dispatched in this paper: 1. the present situation, distribution of the populations, occural characteristics, trend, dominat spsecies and netural enemy of the apple insect pest in Shandong; 2. the occurrence and relations with enviroment of apple fruit borer Carposina nipponensis Walsingham; 3. the studies on the population dynamics of two mits, Panonychus uimi(Roch) and Tetranychus viennensis Zacher; 4. occurrence and harmfulness of Lugus lucorum(Meyer-Diir) in orchard; 5. demonstrating of two orchards about 300 mu IPM for apple insect pests. The results showed that the strategies needed spraying poison 6 times annual, in which pesticide 4 times -lessen 2～ 3 times than routine control area, and fruit damage rate were 0.22% and 0.39%, disease feuit incidence were 0.55% and 0, and disease leaf incidence were 4% and 12.2%.
