Some researchers have obtained information about the food of predators (birds nest) as an insect the size below 5 mm. This research aims to identify and isolate D. melanogaster in a natural culture medium of shoes banana, star fruit and guava as well as knowing the number of population D. melanogaster as well as calorific value, proteins, fats, carbohydrates and minerals from the artificial media.
