Here's the difference between the Queensland fruit fly (native to QLD) and the Mediterranean fruit fly, which is an introduced species.

I found both species attacking my pomegranate fruits today and thought I'd snap a pic of them - little buggers :mad:

The images aren't the best but the first one is the QLD fruit fly easily distinguished by the yellow markings on the brown body and stinger in the abdomen.

And, the Medfly has an orange coloured body with dark wings and spots.

In my backyard it does seem like they do attack the same fruits but the QLD fruit fly is the most dominant by far and this is one of just a few Mediterranean fruit flies I have seen actually.

I wonder if the QLD fruit fly being native is out competing the Medfly?

I've been told fruit fly can infect at flower stage, so when is the best time to net ?

Fruit fly generally sting ripening fruit because it gives the larvae the best chance of developing.

Most of the time when fruit fly does sting hard green fruit the maggot won't survive. However, fruit fly strike can induce early fruit drop in unripe produce still developing on the tree/plant.

The best time to net is straight after flowering or just as the fruit is starting to grow.
