The commonly used beaking yeast combinations (yeast, molasses, wheat flour and natural oil extracted from soybean plants), petroleum oil fractions (Royal oil, CAPL 1 & CAPL2 & Sisi 6) and some plant extracts (Jojoba oil, Glue & Gum) were evaluated against Aphis gossypii (Glover), A.craccivara (Koch.), Myzus persicae (Sulzer), and the cereal aphids Schizophis graminum (Rend.) and the oat cheery bird aphid (Rhopalosiphum padi (L.). These treatments were compared in efficiency with some conventional insecticides such as Malathion 57%, Reldan 40%, and Deltanete 40%. Yeast combinations either alone or mixed with natural oil, however, showed no potency as aphicides under lab. or field conditions. Data also, revealed that Jojoba oil (plant extract), CAPL1 & CAPL2 (petroleum oil fractions) exhibited higher effectiveness.
