بررسی تحمل بعضی از ارقام مرکبات روی پایه های مختلف نسبت به پروانه مینوز در استان مازندران

Citrus Leaf Miner is one of the most important citrus pest in North of Iran recently. Using of tolerant cultivars is one of the control methods in integrated pest management. In this research six cultivars (Washington navel, Marss, Thamson navel, Moro, Salustiana and Italian) on four rootstocks (Sour orange, Citrumelo, Yuzu and Shell Mahalle ) was evaluated to infection by Citrus Leaf Miner. Experimental design was a factorial experiment with two factors (variety and rootstock) based on , Randomized Copelete Block Design with 4 four replications in Kotra and Khorram Abad Citrus Research Station (tonekabon) as a raifted and irigated condition respectively. To evaluate of leaf infection in orchards 10 leaves of new shoots were collected of each replication and larva,on the two surface of leaf were counted. The results indicated that there were significant differences among the cultivars to infection by citrus leaf miner in It a=0.0 lin Khoram Abad station. According to Comparison means in Duncan's test, Marss with 36.22 and Thamson navel,italian and Moro with 31.55,31.47 and 31.45 larva per ten leaves had the maximum and minimum infections. There were no differences among the cultivars in Kotra station and also among rootstocks in both stations. Comparing rootstocks and cultivars interactions indicated that in Kotra Salustiana on Shell Mahalle Moro on Sour orange with 36.47 and 30.69 and in Khoram Abad Mars on Shell Mahalle and Moro on Shell Mahalle with 36.89 and 28.77 larva per ten leaves had the maximum and minimum infections respectively.
