Biological Performance, Development and Life Table of Bird Cherry-Oat Aphid Rhopalosiphum padi (L) (Hemiptera: Aphididae) on some Egyptian Wheat Cultivars

Abstract

The bird Cherry-oat aphid Rhopalosiphum padi (L) causes serious damage in cereal producing countries including Egypt. The biological performance and development of R. padi on ten Egyptian wheat cultivars including

Susceptibility of Certain Egyptian Wheat Cultivars to Greenbug, Schizaphis graminum (Rondani) (Homoptera: Aphididae) Infestation

“…The percentage of nymphal survival varied from highest on Beni Suef 5 (96.1%) to lowest on Sids 12 (86.3%). These results in agreement with Taheri et al (2010) and Aly (2018) who found that the developmental time and mortality of nymphal stage of aphids indicated significant differences among the examined wheat varieties. The values are presented as means ± SE of ten replicates.…”
