Abstract
Sixteen rice varieties and promising lines were evaluated at two growth stages, for resistance to feeding by the rice stem borer; Chilo agamemnon Bles. larvae using laboratory methods. Study reported here showed that :- A)At tillering stage Larval mortality: Giza 167, GZ 4294-10-2, Todorokiwase, GZ 4256‌7-4-7 and GZ 4122-23-4-2 were the most resistant entries causing from 20.0 to 55.6% larval mortality. Larval duration: Todorokiwase, GZ 4294-10-2 and Giza 176 were the most resistant entries resulting in longest developmental periods of larvae ranging from 32.3 to 35.2 days. Pupal duration: Todorokiwase and Giza 176 were the most resistant entries resulting in longest duration periods of pupae ranging from 7.0 to 7.7 days. Pupal weight: Todorokiwase and Giza 176 appeared to be the most resistant entries resulting in least weights of pupae ranging from 40.2 to 24.6 mg. Adult longevity: Telle Hamsa and Toride-1 were the most resistant entries with longest adult longevity ranging from 9.0 to 7.6 days. B)At flowering stage Larval Mortality : GZ 4071-16-2-1 and Kagahikari were the highest resistant entries causing 42.6 and 35.0% larval mortality. Larval duration:GZ 4071-16-2-1 and Kagahikari were the highest resistant entries with 34.6 and 33.2 days as longest duration of larval feeding. Pupal duration: GZ 181 and Kagahikari were the highest resistant en‌tries with longest pupal duration ranging from 8.9 to 7.2 days.
