在密歇根州南部的17个苹果园中，至少有6种植食性螨，18种捕食性螨，和>5种的碎屑和真菌喂养螨在2年的采样中被发现在苹果叶上。具有最大体积（生物量）的物种包括柱头类捕食者Agistemus fleschneri Summers和Zetzellia mali（Ewing）、植节类捕食者Neoseiulus fallarium（Garman）和叶螨类食草动物Panonychus ulmi（Koch）。废弃果园中螨类的数量与商品果园中螨类的数量相关。然而，几个物种的高容量在废弃果园有一个低容量或没有在商业果园。当果园没有喷洒杀虫剂时，捕食者物种的转变在一个季节内迅速发生。捕食者的体积小于草食动物的体积在商业果园，但在废弃果园的情况正好相反。
At least 6 species of herbivorous mites, 18 species of predatory mites, and >5 species of detritus- and fungus-feeding mites were found on apple foliage during 2 yr of sampling in 17 southern Michigan apple orchards. Species with the greatest volume (biomass) included the stigmaeid predators Agistemus fleschneri Summers and Zetzellia mali (Ewing), the phytosdeiid predator Neoseiulus fallacis (Garman), and the tetranychid herbivore Panonychus ulmi (Koch). Volume of mite species in abandoned orchards was correlated with their volume in commercial orchards. However, several species with high volume in abandoned orchards had a low volume or were absent in commercial orchards. A shift in predator species took place rapidly over a single season when orchards were not sprayed. Predator volume was less than herbivore volume in commercial orchards, but the reverse was true in abandoned orchards.
