Fruit Fly Imaginal Discs - Haltere and Wing
Featured above are fluorescence digital images of triple-labeled Drosophila (fruit fly) haltere and wing imaginal discs, labeled with fluorescent antibodies to apterous (wingless mutant) in red, vestigial (short winged mutant) in blue, and Cubitus interruptus (Ci) in green.
After the fourth larval molt of the fruit fly, an immobile pupa emerges. The pupal fruit fly is brown, with two horn-like protrusions, and it takes an additional four to six days at this stage for the fruit fly to achieve its adult form where it has reached its full size, and has a fully developed reproductive system. The female fruit fly drops eggs until she dies, producing hundreds of offspring. Eight days later, the cycle begins again and her offspring are off to the races, making them very effective pests.
