Abstract In order to characterize associations between lipids and polypeptides of the Chilo Iridescent Virus (CIV) unit membrane, lipophilic polypeptides were selectively extracted from purified particles and analyzed. Polypeptides of MW 11 000, 12 500, 16 000, 18 000 and 50 000 were identified by electrophoresis: P11 000 seems to be linked with a fatty acid (palmitic acid), P12 500 is a DNA‐binding protein and remains as a contaminant in lipophilic compounds, P16 000, P18 000 and P50 000 are strongly associated with phospholipids as phophatidylinositol (PI) in majority and phosphatidylcholine (PC). This result is of particular interest to explain the high proportion of PI in lipid analysis of the viral membrane.
