Abstract
Wheat, Triticum aestivum L. is an important cereal crops in Egypt. Corn leaf aphid, (Rhopalosiphum maidis Fitch) a species of aphid attacks plenty of the Gramineae plants and most cereal crops. The biological attributes of R. maidis reared on the nine wheat varieties, namely, Sids-12, Sids-14, Gimmiza-11, Giza-171, Misr-2, Bani suif-5, Bani suif-6, Suhag-4 and Suhag-5 were studied. The wheat varieties differed significantly in the duration of 1st, 2nd, 3rd and 4th nymphal instars. Wheat varieties effect significantly on the total developmental time of nymphal stage. The highest developmental time was recorded on Sids-14 variety with 5.80 days. On the other hand, data showed no significant differences between the nine wheat varieties in reproductive period. Bani suif-5 variety recorded the highest average number 11.90 days. On the other side, the aphids reared on Gimmiza-11 variety recorded the lowest average number 9.25 days. Data showed that the total number of offspring per female and mean number of offspring/day affected significantly by wheat varieties. There are a significant differences in longevity and generation period of R. miadis reared on the wheat varieties examined.
