✦ Synopsis

Following gas chromatographic analysis of citruspeel oils, 30 components of these oils were tested against Callosobruchus rnaculatus (F.). Several compounds (22), including the major component of all citruspeel oils--( +)limonene-were found to be bioactive, having a strong vapour insecticidal activity. These components and some of their isomers were shown to have varying levels of activity (a-terpineol, 24-h LC,, 4.05 pl litre-' to n-tridecane, LC,, 13.3 p1 litre-I), but no single component could account for the activity measured for a typical citruspeel oil (lime) on a proportional basis. Joint action studies established that in artificial mixtures several pure components of citruspeel oil potentiated their individual fumigant action in a manner consistent with an additive model against C. maculatus.
