Managing Mediterranean fruit fly in backyards | Department of Agriculture and Food WA


The fruit fly in Western Australia is an enormous problem for commercial fruit producers and is also a menace to the backyard fruit growers. It renders fruit inedible and it’s been with us since 1895. Mediterranean fruit fly is about the size of a housefly its
brown in colour has got patterned wings quite an attractive fly but a
devastating menace. One of the things we would like to get people involved with is the use of a calendar at home, to actually mark when
there fruit is about to be harvested and even
before that when the fruit is half formed and with these stages of fruit development you can time your activities. Having a fruit tree is a little bit like having a pet and of course you must
clean up after it pick up falling fruit and put it into a black plastic bag seal up the bag and
then leave it in the sun for a week and they will kill off any
eggs or larvae maggots there are in the fruit. Organic foliar fruit fly baits are available and I’ve got one here and we just going to measure the solution putting it into the water so this contains molasses and a natural insecticide to kill off the
fruit fly. It’s always important to read the label. It will give you specific ways in which
you can mix and apply the fruit fly foliar bait. Were just using a simple home type pressure sprayer, pump up type. Just going to give this a few pumps. [pump, pump, pump] and what we want to do when we apply the foliar bait is to have it coming out as the course steam so we putting a food source onto the
leaves, that’s going to attract the fruit fly and kill
them. Baiting should be done at least once a week and preferably twice a week in the warmer months. Fruit fly trapping is an effective way of reducing the fruit fly population in your backyard and reducing the damage to your fruit. You can either buy a commercial trap or you can make your own from a cool drink bottle. Starting with the later of water to which we heading 50 mil of cloudy ammonia, which you can buy the
supermarket adding to that a tablespoon of sugar 5 mil of vanilla essence tablespoon of the yeast extract and then mix it in. [water sloshing] So you want to fill this just to below the holes that you’ve put in with your soldering iron and it’s ready to go. Once you put your trap in place keep an eye on the solution and we
recommend changing the lure every week. And another way to prevent fruit fly damage is to prevent access of the fruit fly to your fruit. You can do this by either using netting or you can buy commercially available bags. Paper bags or cloth bags or mesh bags are all available. Following all those control practices will enable you to enjoy your homegrown fruit.
