在俄勒冈州胡德河谷的4个苹果园中，西色拟甲虫成虫在0、10和100m的下风向迷你苹果园的迁徙速度和速率均高于黄粉虫。西方根结线虫在民果园的定殖速度也较快。不同树种之间的迁移率是相似的，通过移动到放置在树上的树来衡量，但不接触来源果树。扩散和定居可能受到固有的生理和形态属性、食物习惯以及对猎物和栖息地要求的反应的影响。讨论了它们的扩散和定植对生物防治和抗药性管理的意义。
Adult female Metaseiulus occidentalis Nesbitt immigrated faster and at higher rates than did Typhlodromus pyri Scheuten to mini-orchards of young apple trees at 0, 10 and 100 m downwind from four apple orchards in the Hood River Valley, Oregon. Colonization of min-orchards also was faster by M. occidentalis. Rates of emigration were similar between species as measured by movement into trees placed within, but not in contact with source orchard trees. Dispersal and colonization may be influenced by intrinsic physiological and morphological attributes, food habits, and responses to prey and habitat requirements. Implications of dispersal and colonization by these mites to biological control and pesticide resistance management are discussed.
