The humid-adapted species Neoseiulus fallacis (German) was the most common phytoseiid mite collected in either humid (> 100 cm annual rainfall) or arid (20-45 cm annual rainfall) mint growing regions of Washington, Oregon, Montana, Idaho, and California during 1991-1995. In experimental field plots, this predator gave excellent biological control of Tetranychus urticae Koch on mint grown under arid conditions in central Oregon when evaluated by an insecticide check method or by the caging of mites. N. fallacis is effective as a predator in arid areas probably because regular irrigation creates a humid environment in the canopy. The selective miticide propargite, when used in combination with predators, was effective at reducing high spider mite populations to below the treatment threshold faster than did N. fallacis alone.
适应潮湿环境的物种伪钝绥螨（German）是1991年至1995年期间在华盛顿、俄勒冈、蒙大拿、爱达荷和加利福尼亚州潮湿（年降雨量>100厘米）或干旱（年降雨量20 - 45厘米）的薄荷种植区采集到的最常见的植绥螨。在试验田块中，当通过杀虫剂对照法或螨类笼养法评估时，这种捕食者对俄勒冈中部干旱条件下种植的薄荷上的二斑叶螨科赫氏叶螨具有出色的生物防治效果。伪钝绥螨在干旱地区作为捕食者很有效，可能是因为定期灌溉在树冠层创造了潮湿的环境。选择性杀螨剂炔螨特与捕食者联合使用时，比单独使用伪钝绥螨能更快地将高螨种群数量降低到防治阈值以下。
