Some Biological Aspects of Rhopalosiphum maidis (Fitch) Reared on Five Corn Hybrids under Laboratory Conditions
ABSTRACT The effects of five corn hybrids on some biological parameters of R. maidis were studied under laboratory conditions. The lowest developmental time of nymphal stage was recorded on Hi-Tech-2066 with 5.13 days. The highest mean number of offspring was recorded on Hi-Tech-2066 (46.20 nymphs/ female), while Hybrids Watania-6 and 131 gave the significantly lower mean number of 30.67 and ... إقراء المزيد
