A closely related structure such as 3,5-dimethyl-1,2-dihydroxyocta-6-one (LXXVIII), as suggested by Phillips et al. Ecol. Adult lifespan is approximately 6 months. The pupal stage lasts about twice the duration of the egg stage at a particular temperature and adults are short lived, females laying most of their 2–300 eggs within 3 days.

A thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science m Seed Technology at Massey University, Palmerston North, New Zealand. Behavioral responses to food volatiles by two species of stored-product Coleoptera, Sitophilus oryzae (Curculionidae) and Tribolium castaneum (Tenebrionidae). It has also been suggested that acetogenins play a crucial role in the biosynthesis of the sex pheromones of the tobacco beetle, Lasioderma serricorne (Chuman et al., 1983; Phillips et al., 1985).
