The secretion from the rectal pheromone glands of maleDacus tryoni andDacus neohumeralis is largely a mixture of six aliphatic amides. In order of decreasing quantity these areN-3-methylbutylpropanamide,N-3-methylbutylacetamide,N-(3-methylbutyl-2-methylpropanamide,N-2-methylbutylpropanamide,N-2-methylbutylacetamide, andN-(2-methylbutyl)-2-methylpropanamide. The proportions of the various amides in the two species are similar.
