Abstract

Triglycerides of Nigrospora sphaerica which elicit aggregation of adult confused flour beetles were separated according to their degree of unsaturation by chromatographic methods. Several fractions showed activity. The largest and most active fraction consisted of monounsaturated triglycerides of which the major component was oleodipalmitin. Triglycerides from three other fungi showed varied levels of activity.
