| 摘 要： | 1987～1988年田间应用试验表明,青岛地区生态条件可以满足伪钝绥螨生存和发展的要求.5月下或6月初,以1:50的益害比,释放伪钝绥螨,可控制苹果全爪螨为害,减少果园施用杀螨剂3次。伪钝绥螨在当地可以自然越冬,完成周年循环,建立种群,成为控制叶螨发生的有效天敌。

| Abstract: | During 198.7-1988, releases of A. failacis were made in theapple orchards of Qingdao, Shandong Province, to control the redspider mite, Panonychus ulmi. Releases in late May or early Juneat a predator:prey ratio of 1:50 resulted in a successful controlof P. ulmi. The infestation level by P. ulmi was kept at 4-10adults/leaf throughout the growing season. The use of miticidewas reduced by 3 applications in the releasing year. The predatorestablished its natural population and overwinterred under theground cover. The population dispersal of A. failacis between theapple trees and the ground cover was also studied. |
