. Female Lucilia sericata Mg. fed a reproductive diet of meat were sterilized by injection of 10μg of tepa. Light microscopy revealed that the medial neurosecretory cells of the brain of sterilized flies were highly active compared with the same cells in untreated flies of similar age and nutritional status. The corpora allata of sterilized flies were also greatly enlarged. The evidence suggests that developing oocytes secrete a substance that inhibits the corpora allata hormone, thereby suppressing brain neurosecretory cell activity and preventing oogenesis in the subsequent oocytes.
