Abstract

Powdered dried ginkgo tree leaves were subjected to various chemical extractions and successive extracts were monitored for antifeedant activity against larvae of Pieris brassicae. Many fractions moderately inhibited food intake, and some were deterrent at levels as low as 25–50 ppm. Some behaviourally highly active fractions were tested electrophysiologically for neural responses in the maxillary taste sensilla. These extracts appeared to stimulate deterrent receptors. There were distinct differences in responses between Pieris brassicae and P. rapae. Ginkgolide A, B, and C each strongly stimulated deterrent receptors in P. rapae, which corresponds with the observation (Matsumoto & Sei, 1987) that these compounds are effective antifeedants for this species. No toxic effects were observed in insects after feeding for 24 h on diets containing ginkgo extracts.
