Abstract:		"Morphological location of the sex pheromone producing area in the ovipositor of the female corn earworm Helicoverpa zea, was correlated with gas chromatographic analysis of the extracted pheromone. Histological studies showed that the pheromone gland occupied an almost complete ring of specialized columnar cells between the 8th and 9th abdominal segments. Ultrastructure of the pheromone gland cells revealed distinct features such as microvilli, pockets of granular material, intercellular canals with abundant desmosomes. Apparent changes in some of these features are associated with phases of pheromone production and non-production. Examination of the tissue with low temperature scanning electron microscopy showed the presence of excreted droplets at the tips of cuticular hairs in the glandular area during the period of pheromone production"
