  Reaction of some almond cultivars including Sefid, Mamaei, Rabie, Non pariel, Shahrood 6, Shahrood 7, Shahrood 13, Shahrood 21 and Shahrood 12 to almond spider mite. Schizotetranychus smirnovi Wainst. Were evaluated in Saman region, during 2008-2009. In the first trial, after grafting of cultivars on GF677 root stock, they were transferred to an orchard and were kept under  insect  net  to prevent natural infestation. Cultivars were infested artificially by introducing 5 adult female mites on each plant. Twenty one days after infestation, leaves were collected and mite population density (number of eggs, nymphs and adults) were counted. Results indicated that Sefid and Feraduel (Shahrood 12) cultivars supported the highest mite population; whereas, Shahrood21 and Shahrood 6 supported the lowest mite population. In the second trail, almond cultivars were evaluated under natural infestation during 2 sampling times (with 15 days interval). Mean comparison of the mite population density (eggs, larvae, nymphs and adults) showed that Mamaei cultivar (mean 63 and 206.2 mites in the first and second sampling times, respectively) supported the highest; whereas, Shahrood 21 (mean 6.2 and 22 mites) supported the lowest mite population density.  Study density of leaf trichomes and concentration of leaf total phenolic compounds showed that there was not significant positive relation between them and resistance to the mite.
