A tansy (Tanacetum vulgare L.) extract was made by grinding fresh tansy leaves in distilled water. The extract, when "painted" on broccoli leaf discs, was found to deter feeding of two of three lepidopterous larvae studied. When the tansy extract was "painted" on the entire body surfaces of the larvae of three lepi dopterous species, no deleterious reactions were observed.
