How do fruit fly damage fruit?
Fruit flies damage fruit by causing rots and discolouration, and by laying eggs which release maggots within the fruit.
The female fruit fly pierces the skin of the maturing fruit and lays eggs just below the surface.
Larvae (maggots) can emerge from the eggs just two days later. The larvae feed on the flesh of the fruit, often tunnelling deep, causing the fruit to rot and drop to the ground.
Queensland fruit fly larvae carry bacteria that breakdown the fruit.
