Abstract
Abstract Seven compounds, ( Z )-5-, ( Z )-7-, ( Z )-8-, ( Z )-9-, ( E )-11-, ( Z )-11-tetradecenyl and ( Z )-10-hexadecenyl acetates were found in the sex pheromone glands of 18 New Zealand Tortricinae moth species. They were divided into two distinct groups according to biosynthetic origins; those derived from a Δ 9 - or Δ 10 -unsaturated intermediate [( Z )-5-, ( Z )-7-, ( Z )-8-, ( Z )- IO -] and those derived from a Δ 11 -unsaturated intermediate [( E )-11 and ( Z )-11-]. The origin of ( Z )-9-tetradecenyl acetate was assigned to either group according to the biosynthetic origin of other compounds found in the gland. Morphological examination supported the chemotaxonomic interpretation that species using Δ 9 - and Δ 10 -unsaturated derived components (i.e. all Ctenopseustis and certain members of Planotortrix ) are distinct from the species that use Δ 11 -unsaturated derived substances (i.e. the remaining members of Planotortix and those from Catamacta , Ecclitica , Pyrgotis and Merophyas .
