Antifeedant properties of destruxins and their potential use with the entomogenous fungus Metarhizium anisopliae for improved control of crucifer pests.

Destruxins A, B and E, produced by the entomogenous fungus Metarhizium anisopliae, are insecticidal but comparatively low doses have antifeedant properties.  Treatment of cabbage leaf discs with destruxins significantly reduced feeding by larvae of Plutella xylostella and Phaedon cochleariae in both choice and no-choice assays.  The Antifeedant Index (AI) was dose related and there were significant differences between treated and untreated leaves.  The AI and acute toxicity assays suggest that insect death was due to a combination of the starvation and loxicity effects of destruxins.
