Abstract :In this study carried out during 1995-1996, population development f aphids on Sorghum spp., Seteria italica (L.) P.B. and Phalaris canariensis L. was observed. Rhopalostphum maidis (Fitch) (Hom: Aphididae) and Diuraphis noxia (Kurdjumov) (Hom: Aphididae) were dominant aphid species on Sorghum spp. and P. canariensis , respectively. None aphid population on S. ttalica and a low level population of R. maidis on sudangrass [Sorghum sudanense (Piper) Stapf] were determined. Except white colour sorghum, all varieties and populations of Sorghum vulgare Pers. Sorghum bicolor (L.)] examined were very susceptible against R. maidis.
