geranyl diphosphate
myrcene + diphosphate
the acyclic monoterpene myrcene is required for the production of the major aggregation pheromone component, ipsdienol

geranyl diphosphate
myrcene + diphosphate
bifunctional enzyme: geranyldiphosphate synthase (EC 2.5.1.1)/myrcene synthase (EC 4.2.3.15). When the recombinant enzyme is incubated with dimethylallyl diphosphate and isopentenyl diphosphate as cosubstrates, the level of geranyl diphosphate formed is approximately tenfold higher than the level of myrcene formed. The data suggest that geranyl diphosphate is a free intermediate in myrcene production
