Enantiospecific effect of limonene and limonene-derived bicyclic lactones on settling and probing behaviour of the peach potato aphid Myzus persicae (Sulz.)
Journal of Plant Protection Research 43 (2), 133-142
Abstract: The deterrent effect of limonene enentiomers and limonene derivative: (+)-(1S,4S,6S)-4-(1-methylethenyl)-9-oxabicyclo[4.3.0]nonan-8-one, on Myzus persicae was investigated. Only S-enentiomers of limonene and its derivative, showed feeding deterrent properties. S-limonene inhibited phloem sap ingestion, and reduced the number of phloem sap ingestion phases during aphid stylet penetration of plant tissues. Aphids spent twice less time on leaves painted with (+)-1S,4S,6S-4-(1-methylethenyl)-9-oxabicyclo[4.3.0]nonan-8-one than on control and S-limonene-treated leaves and the probes were shorter than 2 minutes on these leaves. Our studies confirmed that the chiral centre configuration of the lactones was important in expression of feeding deterrent activity.
