Among the first to use fruit flies as objects Genetic research is Thomas Hunt Morgan who managed to find the discovery of sexual origin. Species of fruit fly, Drosophila melanogaster, a kind of common insects that are generally harmless. During the summer of Drosophila is present in all parts of the world and one of the common species to infest fruits are ripe and waste places.
General characteristics of the Drosophila anataralain, tawny body color with black rings on the back of the body, small size, between 3-5 mm, the edge of the wing veins (costal vein) has two parts terinteruptus close to his body, tentacle (Arista) general form of feathers, has 7-12 branches, posterior crossvein is generally straight, not curved. Compound eyes are round and colored red ellipse rather, there oceli eye on top of the head with a smaller size than the compound eyes, hair, hairy thorax with a white background, while the five-segmented abdomen and black striped, long wings,, colored transparent, and position stems from the thorax
Fruit flies (Drosophila) easy to breed and have a relatively short life cycle. Period of development of Drosophila melanogaster, among others, the temperature varies, generally all kinds of cold-blooded. The shortest development time (egg-adult), is 7 days, and achieved at 28 ° C. Metamorphosis in Drosophila, including metamorphosis, from egg – larval instars I – larval instar II – III instar larva – pupa – imago. Factors affecting the growth of the life cycle of Drosophila melanogaster including ambient temperature, the availability of food media, the density of the maintenance vial, the light intensity
