Abstract
Jar tests were carried out in the laboratory in Egypt to determine the susceptibility of different types of grain to attack by Sitophilus oryzae (L.) and S. granarius (L.). The number of adults emerging 4 weeks after artificial infestation showed that the rice variety Nahda was the most resistant to attack by the former weevil, followed by the maize varieties Early American and Giza Balady, the sorghum variety Giza 114, the wheat varieties Super X and Giza 155 in that order, while Nahda was also the most resistant to the latter weevil, followed by Early American, Giza Balady, Giza 114, Super X and Giza 155. It was found that the rearing diet of adults of S. oryzae significantly affected the numbers and food preference of F1 adults. Parents reared on Early American produced the most offspring, followed by those reared on Giza 155 and those reared on Giza 114. Infestations were heavier on wheat than on sorghum or maize irrespective of the parental diet. Comparison of the infestation levels on sorghum and maize indicated that the progeny preferred the type of grain on which their parents had been reared
