Ozder, N. (Trakya University, Tekirdag (Turkey). Dept. of Plant Production)
Nymphal development time and fecundity of Sitobion avenae (F.) were determined on nine widespread wheat varieties cultivated in Tekirdag Region in Turkey. Tests were carried out in controlled environment chambers (25 plus minus 1 degree centigrade, 65 plus minus 5% R.H. and 16:8 light and dark cycle). Developmental time ranged from 5.75 plus minus 0.25 to 7.20 plus minus 0.20 day. Fecundity was found the highest (12.87 plus minus 1.50) on cv. Sana. Cv. MV-17, cv. Miryana, cv. Pehlivan and cv. Saraybosna were found particular resistant wheat varieties against S. avenae.
