Fungal isolates of two species of the genus Trichoderma were evaluated as antifeedant compounds towards winged and wingless morphs of the aphid Schizaphis graminum and wingless morph of Megoura viciae. The three tested isolates resulted repellent towards winged morph of S. graminum and wingless of M. viciae; only T. citrinoviride proved to be repellent towards wingless of S. graminum. Electrophysiological studies showed that the structures involved in the perception of the fungal metabolites are located on the aphid tarsomeres supporting the hypothesis that at least part of the fungal metabolites responsible for the repellent effect are water soluble compounds.

Abstract

Fungal isolates of two species of the genus Trichoderma were evaluated as antifeedant compounds towards winged and wingless morphs of the aphid Schizaphis graminum and wingless morph of Megoura viciae. The three tested isolates resulted repellent towards winged morph of S. graminum and wingless of M. viciae; only T. citrinoviride proved to be repellent towards wingless of S. graminum. Electrophysiological studies showed that the structures involved in the perception of the fungal metabolites are located on the aphid tarsomeres supporting the hypothesis that at least part of the fungal metabolites responsible for the repellent effect are water soluble compounds.
