Abstract

The RUSSIAN WHEAT APHID globally regarded as a serious pest of barley and wheat varieties, has been reported from Iran, (1954) and East Azarbaidjan province since 1971 with widespread distribution particularly in Tabriz, Ahar and Kaleybar wheat fields. Five Iranian WHEAT CULTIVARS, namely Sardari, Sabalan, Alvand, Zarrin and Alamoot, the most extensively cultivated varieties in the province, were used in laboratory screening test for assessment of their ANTIBIOSIS resistance to the aphid at the stem elongation growth stage. The resistance at the tillering growth stage of the same cultivars has been previously evaluated under separate experiments.This work was carried out under glasshouse conditions of 23.3±0.99°C Temp., 45-55% R.H. and 14:10 (L:D) light regime. ANTIBIOSIS was assessed by studying the developmental time, nymphal survival rate and adult fecundity (total no. of progeny / female produced within the first 10 and 15 days of reproductive stage), and by calculating the relevant intrinsic rate of natural population increase (rm value). The ANDVA of the data indicated that, regarding the two last characteristics, there was significant differences (P<0.05) between the varieties. The highest and the lowest mean number of progeny for 10 and 15 days of reproduction was obtained in rearing on Alvand (28.2±6.57 and 43.05±8.49) and Sardari (21.58±7.73 and 35.11±13.22), respectively. Also the highest mean (rm) value (0.2485±0.01 and 0.2553±0.01) was estimated for rearings on Zarrin with the lowest being 0.2224±0.03 and 0.2305±0.03 in rearings on Sardari variety. The results showed that Zarrin was more susceptible to the aphid than the other varieties with Sardari appearing sthe most resistant one. Alvand, Sabalan and Alamoot were regarded as intermediate among the others. Further experiments with later phonological stage of the cultivars and potential role of other resistance mechanisms are under way.
