Toxicity of lignans to symbiotic fungus of leaf-cutting ants

J Chem Ecol. 1996 Jul;22(7):1325-30. doi: 10.1007/BF02266969.

Abstract

Lignans fromVirola sebifera Aubl.,Virola sp., andOtoba parvifolia (Mkfg.) A. Gentry (Myristicaceae) inhibited the in vitro growth of the fungus cultivated by leaf-cutting ants of the speciesAtta sexdens rubropilosa Forel (Hymenoptera: Formicidae). A comparison of activity among the lignans was obtained.
