ارزیابی مقاومت و حساسیت چهارده ژنوتیپ لوبیا سفید و قرمز به کنه تارتن دو لکه‌ای Tetranychus urticae Koch.

Resistance of 14 genotypes of red and white bean (including: D₃, D₁₀, D₁₂, D₈₁₀₈₃, BRB₁₈₈, ARS-R₉₃₀₀₃, Sayad, Daneshkadeh, Sadaf, Dehghan, Kara casehiro, Goynok₉₈, Jules, G-11867) to two-spotted spider mite in laboratory and greenhouse conditions were studied. Lab studies were conducted using leaf disk bioassay with introducing 5 adult female mites on 2 cm diameter leaf disk and recording number of eggs, mite mortality and host damage after 72 hrs. In greenhouse conditions, when plants grew to 2 leaves stage, infestation was done by introducing 5 adult female mites (3-5 days in age) and mite population was studied after 2 weeks. Moreover, host perference and concentration of phenolic compounds were measured. Results indicate that Kara casehiro is the most susceptible, whereas Dehghan and D₈₁₀₈₃ are the most tolerant genotypes. There was no relationship between concentration of phenolic compounds and resistant to two-spotted spider mite.
