本文描述了商品苹果园捕食性植食性叶螨Amblyseius veracis(Garman)在生长季节内在地被物、树冠下空气、树干和树叶上的扩散与环境因素和在上述生境中的天牛及其猎物全爪螨、二斑叶螨和纹叶螨的密度的关系。来自果园地被物的松材线虫最初对树木的定植涉及到了流动和空中的传播方式。自1月1日以来的平均总摄氏261°0(12.2°C)，加上地被捕食者和猎物的存在超过一片苹果叶，即一片苹果叶上的二尖杉+麻疯树+(A.schlechtendali/15)的数量，是柳杉定殖树的先决条件。此外，还报道了松材线虫为应对猎物而从树上向果园内外的地点扩散的密度非依赖和依赖的方面。
Dispersal of the predatory phytoseiid mite Amblyseius fallacis (Garman) within the ground cover, the air beneath the tree canopy, on the tree trunk and on tree foliage of commercial apple orchards during a growing season is described in relation to environmental factors and densities of A. fallacis and its prey Panonychus ulmi (Koch), Tetranychus urticae Koch, and Aculus schlechtendali (Nalepa) in the aforenamed habitats. Ambulatory and aerial means of dispersal were involved in initial colonization of trees by A. fallacis coming from the orchard ground cover. A mean total of 261°0 (base 12.2°C) since January 1 plus the presence of predators in the ground cover and prey in excess of one P. ulmi equivalent/apple leaf, i.e., the number of P. ulmi + T. urticae + ( A. schlechtendali /15) on an apple leaf, were prerequisites for tree colonization by A. fallacis . Aspects of density independent and dependent dispersal by A. fallacis from trees to sites within and beyond an orchard in response to prey are also reported.
