Spiroacetal Biosynthesis in Insects. From Diptera to Hymenoptera: A Giant Ichneumon Wasp: Megarhyssa nortoni nortoni Cresson

Schwartz, Brett; Moore, Christopher J; Rahm, Fredrik; Hayes, Patricia Y; Kitching, William; De Voss, James Joseph


The volatile components of the mandibular gland secretion generated by the Giant Ichneumon parasitoid wasp Megarhyssa nortoni nortoni Cresson are mainly spiroacetals and methyl ketones, and all have an odd number of carbon atoms. A biosynthetic scheme rationalizing the formation of these diverse components is presented. This scheme is based on the results of incorporation studies using2H-labeled precursors and [18O]dioxygen. The key steps are postulated to be decarboxylation of β-ketoacid...[Show more]
