Abstract
The effect of grain moth larvae feed onen different cereals on some biological parameters of different stages of insect was studied at 27 ± 1 C and relative humidity from 50 % to 60 %. Results indicated that the higher average of egg oviposition duration 4.6 days was recorded for larvae fed on both of rice grains Amber 33 and barly 265. The higher average of egg incubation periods were 5.2 and 5.1 days when larvae fed on rice grains cv. Amber 33 and wheat cv. Abu - Ghraib, while the higher average of egg laid numbers of insect female were 136.2 eggs when larvae fed on wheat cv. Abu-Ghraib and 132.3 eggs on barley cv. mel . The results also showed that larvae feeding on different grains caused significant in both of larvae stage duration, instar numbers, larval mortality, pupal stage duration, adult duration for both male and female and duration of generation. The highest average of larvae duration was 24.4 days when larvae fed on rice. The highest larvae instar numbers was 5.4 days on rice cv. Amber 33. The highest mortality was 23.1 % when larvae fed on corn cv. Research 106. However the highest average of pupal stage duration 9.1 days when fed on sorghum cv. Encath. The average durations of male and female were 15.6 and 5.9 days when fed on corn. The highest average of generation time was 53.4 days when fed on rice.
