Abstract

The Russian Wheat Aphid, globally regarded as an important cereal pest, has extended its distribution throughout the country and in wheat fields of East Azarbaijan in particular. Biological responses of the aphid to work out any possible SUSCEPTIBILITY or resistance in five extensively planted WHEAT CULTIVARS in the province named as Alamoot, Alvand, Zarrin, Sabalan and Sardari, have been already studied at tillering and stem elongation stages in the greenhouse as well as at 3 growth stages under field conditions by the authors. In the present work, attention has been paid to the biological responses of the aphid on these cultivars at ear emergence stage under greenhouse conditions of 20.52 ± 1.4 temp., 55-70 % R.H. and 14:10 (L: D) regime. The probable ANTIBIOSIS in determination of resistance or SUSCEPTIBILITY of cultivars to the aphid was studied by measuring the nymphal survival rate, mean development time and adult fecundity. Determining the total progeny number / female produced within the first 10 and 15 days of reproductive stages, the relevant intrinsic rate of natural increase (rm value) was estimated. The ANOVA of the data indicated that regarding duration of nymphal development time, adult fecundity and also rm values, there were significant differences (P < 0.05) between the cultivars. Based on this, the highest (8.90 ± 1.0) and lowest (7.90± 0.96) mean nymphal development time was calculated on Alvand and Sabalan respectively. The greatest (34.94 ± 5.91 and 48.56 ± 7.66), and the least (24.83 ± 9.36 and 36.67 ± 13.67), numbers of progeny produced / female within the first 10 and 15 days of larviposition period, was observed on Sardari and Alvand respectively. Moreover, the highest rm value (0.2677 ± 0.02 and 0.2636 ± 0.02) obtained for individuals reared on Sardari, with the lowest (0.2174 ± 0.03 and 0.2234 ± 0.03) being on Alvand. The present study indicated that at ear emergence stage, Sardari appeared to be susceptible to the aphid whilst Alvand and Zarrin were more resistant, and Sabalan and Alamoot showed partial resistance.
