Abstract

The morphology of a sex pheromone‐producing gland found in the abdomen of Drosophila grimshawi males was studied by light and electron microscopy. This gland, consisting of two intra‐anal lobes, contains cells that resemble those of other insect pheromone glands. However, in contrast to many other insect pheromone glands that release pheromone through the cuticle, cells of the intra‐anal lobes secrete into a canaliculi‐duct system that empties into the anal region. The liquid secretory product flows along the surface of the intra‐anal lobes and is brushed onto the substrate by fingerlike projections on the lobes' surfaces.

The three vitellogenin transcripts from Drosophila grimshawi have an average size of 1,600 nucleotides as determined using denaturing electrophoretic conditions. Southern analysis showed that the large quantity of vitellogenin mRNAs in adult female fat body cells is not a reflection of specific gene

The control of Spodopfera littoralis sex pheromone biosynthesis has been investigated with synthetic pheromone biosynthesis activating neuropeptide (PBAN) and different labeled tracers using an in vitro isolated gland system. Responsiveness of the glands to PBAN stimulation was impaired by careless
