The invasive pest spotlight focuses on emerging or potential invasive pests in California. In this issue we are covering the Oriental fruit fly.
Oriental Fruit Fly Facts
The Oriental fruit fly (OFF) is an invasive pest that attacks over 230 crops including citrus and other fruits, nuts, vegetables, and berries. The short life cycle of the OFF allows rapid development of serious outbreaks, which can cause severe economic losses. Heavy infestations can cause complete losses of crops. Fruit that has been attacked may be unfit to eat as larvae tunnel through the flesh as they feed. Fungi and bacteria enter, leaving the interior of the fruit a rotten mass. Infested fruit does not always...

The larvae that hatch inside the fig damage the fruit by feeding on it (Figure 2). The larvae will make their way out of the fruit, drop to the soil and pupate. Some may pupate inside the fig.
