Dihydroactinidiolide is a volatile terpene. It has a sweet, tea-like odor and is used as a fragrance. Dihydroactinidiolide occurs naturally in black tea, fenugreek, fire ants, mangoes, and tobacco. It has also been prepared synthetically. ^[2]

Dihydroactinidiolide is a pheromone for a variety of insects; ^[3] for example, it is one of the three components of the pheromone for queen recognition of the workers of the red fire ant. ^[4]
