Larvae leave fruit through large exit hole. Females exhibit this preference until mating occurs, following which they prefer the host fruit odor. Drosophila spp. Most of the damage to fruit is done by just 2 species - the exotic Mediterranean Fruit Fly on the western side of the continent and the native Queensland Fruit Fly in the east. If a medfly is found, additional traps will be set up to remove as many as possible from the area. After more than a month, millions of dollars of crops had been destroyed and billions of dollars more were threatened.

[citation needed], Ultimately, the infestation was eradicated, but both the governor's delay and the scale of the action has remained controversial ever since. It attacks a range of cultivated fruits and some fruiting vegetables. After inoculating the medfly with Enerobacter cloacae, the researcher extracted the haemolymph from the males and found that it contained potent antibacterial factors compared to the haemolymph of controls. The species originated in sub-Saharan Africa and is not known to be established in the continental United States.
