Tubular Endoplasmic Reticulum

The sex-pheromone-producing gland in female Trichoplusia ni (Hübner) is a modified intersegmental membrane and the gland cells are ductless. Lipid spheres are located throughout gland cells and vary both in number and size relative to the age of the female. Most of the lipid is surrounded by oval to elongate distensions of smooth tubular endoplasmic reticulum which contain the enzyme catalase and are thus microperoxisomes. Lipid spheres evert the apical plasma membrane between microvilli, move away from the gland cells, and are stored in the cuticle as discrete lipid deposits. These deposits, in turn, move to the surface of the gland by tubular structures that differ from epicuticular filaments.

Abstract(E)-9-Dodecenyl acetate (E9-12:OAc) and (Z)-9-dodecenyl acetate (Z9-12:OAc) are major components of the sex pheromone of the cherry bark tortrix (CBT), Enarmonia formosana (Scopoli), in British Columbia. The compounds were identified in extracts of female pheromone glands by coupled gas chromatographic – electroantennographic detection (GC–EAD) and coupled GC – mass spectrometry. In field experiments, traps baited with E9-12:OAc or Z9-12:OAc singly were unattractive to male CBT, but in combination at ratios of 50:50 or 40:60 captured numerous males. Increasing quantities of this two-component pheromone blend resulted in increasing captures of male CBT. This binary blend at a 10-mg dose caught more CBT males that did caged virgin CBT females. Eight other EAD-active acetates identified in extracts of pheromone glands failed to enhance attractiveness of the pheromone blend. These compounds may serve to reduce cross-attraction of heterospecific male moths or may play a role in courtship behaviour. Formulations of synthetic pheromone are being evaluated for management of the CBT using mass trapping or disorientation of male CBT moths.
