There are over 12
different types of Australian native pest fruit fly
The most serious,
the Queensland
Fruit Fly (Bactrocera Tryoni) is a native of the Australian Bush and a
serious insect pest which attacks a wide range of fruits and vegetables
such as peaches, plums, passionfruit, tomatoes, capsicums and
citrus to name a few.
The Queensland
fruit fly is wasp-like in appearance and about 7millimetres (1/4 inch)
long; reddish brown with distinct yellow oval markings.
The female fly
lays eggs in maturing and ripe fruit with the larvae burrowing inside
the fruits and destroying it. Fallen Fruit generally contain fruit fly
larvae which burrow into the ground and emerge as adult fruit flies. It
is Vital that fallen fruit should be collected and destroyed.

Fruit
tree owners are responsible for ensuring fruit is controlled on their
properties and failure to control Queensland fruit fly can lead to
prosecution under the Plant Diseases Act 1924 with fines of up to $11
000. The
cost to Australian agriculture in lost produce from fruit fly attack is
over $100 million annually, mostly attributable to the Queensland fruit
fly. Before the development of agriculture in Australia, fruit flies
bred naturally in the bush and their numbers were kept in check by
natural predators. With the development of large mono-culture crops, we
have supplied the fruit fly with perfect breeding grounds which has
greatly increased its numbers. |
