Two-spotted spider mite) Tetranychus urticae) is one of the most important pests of common bean (Phaseolus vulgaris) in Iran. Common bean seedlings are susceptible to the mite and greenhouse is a suitable environment for two spotted spider mite reproduction. Accordingly, to evaluate the mite resistance, 19 common bean genotypes were planted in a completely randomized design arrangement with three replicates and 4 observations in each replication under greenhouse condition in the Agriculture and Natural Resource College of Tehran University. Number of counted adult female mites and their eggs of each genotype to susceptible standard genotype (Derakhshan) were calculated (%). The mite damage feeding was determined using a 1-4 scale to select the most resistant genotype. Naz genotype had the least number of counted adult female mites and their susceptible eggs between other genotypes. However, the damage scale of genotypes was not significantly different.
