The bottom of the regulatory hierarchy appears to be the same in D. This may be due to their contamination with a female pheromone of the "mounting stimulant" type. We'll provide a PDF copy for your screen reader. Male sexual activity begins on the second day after adult emergence if supplied with a solution of "Marmite" yeast extract and milk, sugar, and water. Protein feeding of the male flies causes a heightening of their potential sexuality. Protein fed assay males are more stimulated by the odour of protein fed females than by that of non-protein fed females, and they show no response to odour of protein fed and non-protein fed males. Though attractive females do not affect the male behaviour before contact they elicit an increased chance of completion of the pattern after encounter, whereas bouts with other males tend to break off in the early stages of courtship. A different regulatory system appears to operate in the hairy maggot blow fly Chrysomya rufifacies where the maternal genotype determines sex. No reactions to a volatile sex attractant could be demonstrated from either sex. Males reject courtship with a "pushing" of the hind legs as in cleaning. Sexual behaviour directed towards newly emerged individuals of either sex is inhibited relative to that directed towards other sexually active males. Abstract The Calliphoridae or blow flies are a family of insects that occupy diverse habitats and perform important ecological roles, particularly the decomposition of animal remains. This operates when a mount persists, and though the chances of orientation and genital extension are reduced the chance of mounting is not. Unlike the model fly Drosophila melanogaster, where sex is determined by the number of X chromosomes, in the Australian sheep blow fly Lucilia cuprina sex is determined by a Y-linked male-determining gene M. A stimulatory effect of the odour of females is demonstrated but a greater effect is seen when the males are able to contact the females. This reduces the duration of mounting and prevents genital contact, otherwise mated females are as attractive as virgins.

Neither is maximal male response to odour from females achieved until the females have reached their 2nd or 3rd day after emergence.
