An atlas of light micrographs of normal and lobeless larvae of the marine gastropod Ilyanassa obsoleta

Summary

The olive fruit fly, Dacus oleae, female incorporated dietary ¹⁴ C-labeled malonate, succinate, glutamate, and propionate into the primary pheromone component, 1,7-dioxaspiro[5,5]undecane (1); but did not significantly incorporate acetate. Explanted pheromone glands when incubated in pH 7 phosphate buffer with [¹⁴C]malonate incorporated the label into 1, but did not incorporate [¹⁴C]glutamate. Incorporation of labeled malonate by incubating explanted glands was temperature and age dependent.
