To identify potential predators of citrus trees pests we monitored phytoseiids in the canopy and on ground orchards for two consecutive years Guilan Province, Iran. The most abundant species, therefore greatest as a biocontrol agent, were Amblyseius herbicolus (Chant) (55.6%) Transeius wainsteini (Gomelauri) (30.6%). Graminaseius graminis is reported first time from A checklist key are given 24 phytoseiid species found
