Bactrocera tryoni (Queensland fruit fly)
Synonyms: Chaetodacus juglandis
The Queensland fruit fly (Bactrocera tryoni) is a species of tephritid fruit fly native to Australia. Adult flies are about 5 to 8mm in length in adult stage. Their larvae hatch in various fruit species, causing significant damage to crops. The fly has been the subject of extensive control regimes including a Fruit Fly Exclusion Zone where it is forbidden to take fruit, and post-harvest dipping of fruit in dimethoate and fenthion.

The Queensland fruit fly (Bactrocera tryoni), also known as Q-fly and QFF, is common in towns and horticultural areas throughout eastern Australia. It was introduced into New Caledonia around 1969 and French Polynesia around 1970. It is now widespread in New Caledonia, French Polynesia and Pitcairn Islands. It was introduced but eradicated from Perth (Western Australia) and Easter Island in the mid-Pacific. More recently, it was detected in Rarotonga, Cook Islands, on the 21st November 2001. Its detection prompted a quick emergency response. The Q-fly is very destructive to a large range of fruit hosts, and has significant economic impacts on the areas in which it lives.
