Abstract
Eversible androconial hairbush-organs of males of Bena prasinana L. smell like alpha-keto-butyric acid, a putative pheromone identified in this organ. The brushes are composed of three different hair types. The fine hairs on the valves (numbering 60,000) which are the major odor source, are easily detached (to serve as pheromone transfer particles?). Electroantennograms indicate the presence of olfactory receptor cells for the keto-acid in both sexes. The possible biosynthesis of the odorant is discussed.
