About Queensland fruit fly and Mediterranean fruit fly

Fruit fly species

There are over 250 species of fruit fly in the family Tephritidae known to occur in Australia but only about ten are pests. Many of these species are native to Australia, while others are exotic to the country.

The two fruit fly species that are of major concern to home gardeners and commercial fruit growers alike are the Queensland fruit fly (Bactrocera tryoni) and the Mediterranean fruit fly (Ceratitis capitata). See below for more on these two species.

Note that control methods are similar for most fruit fly species in the family Tephritidae, including Queensland fruit fly and Mediterranean fruit fly.

  • It is most active from September through to May but can also be active in warmer periods during the winter months.
