Fruit Fly trap­ping

The ma­jor­ity of Queens­land Fruit Fly (QFF) trapped since spring has been trapped in ur­ban lo­ca­tions. Dur­ing Septem­ber 138 QFF were trapped in ur­ban sites while only eight were trapped in ru­ral sites. These are adult flies that over­win­tered suc­cess­fully in favourable spots in ur­ban ar­eas. QFF are start­ing their pop­u­la­tion build up in ur­ban ar­eas and un­less they are con­trolled they will im­pact on fruits and veg­eta­bles ripen­ing in late spring, sum­mer and au­tumn in ur­ban gar­dens and, as they did last year, in com­mer­cial or­chards in au­tumn.

Take action now

Now is the time to do the be­low jobs: 1. Place out or, if you al­ready have them out, recharge (with new lures) fruit fly traps in yards. Use both male­tar­get­ing and fe­male-tar­get­ing traps. Con­tact the GMV Re­gional Fruit Fly of­fice or speak to your lo­cal nurs­ery, pro­duce store or hard­ware store for ad­vice on what traps to use. 2. Check fruit that is ripen­ing now for fruit fly in­fes­ta­tion. If you find in­fes­ta­tions, re­move and de­stroy fruit. 3. If QFF have in­fested your fruit and/ num­bers in your traps build up to around 5 QFF per fort­night you should un­der­take ac­tive QFF man­age­ment such as net­ting and bait­ing. If you are un­sure, speak to your lo­cal hor­ti­cul­ture sup­plier.

Re­move un­wanted trees

The Free Tree Re­moval pro­gram has been ex­tended to in­clude peri­ur­ban and ru­ral res­i­den­tial prop­er­ties. Ap­pli­ca­tions will be as­sessed and pri­ori­tised ac­cord­ing to the risk posed. Ap­pli­ca­tion forms can be col­lected from your Coun­cil’s cus­tomer ser­vice cen­tre.

Check­ing fruit for in­fes­ta­tions

If you have fruit­ing plants with ripen­ing fruit in your yard, in­spect them ev­ery cou­ple of days from the be­gin­ning of Septem­ber and through­out the sea­son to check for fruit fly stings. Fruit to pay at­ten­tion to in­clude lo­quats, apri­cots and berries. Some­times QFF st­ing marks can be seen on fruit as black spots sur­rounded by rot­ting tis­sue un­der the skin. The fruit can be cut open and searched for lar­vae (mag­gots) or a knife point can be placed into the skin un­der the st­ing mark and lev­ered up to push eggs out through the wound. You will need a mag­ni­fy­ing glass to see the eggs, as they are only 1.3mm long, 0.3mm wide and shaped like a milky white banana. Some­times you can squeeze the fruit at the st­ing mark and the eggs then pop out through the wound. For as­sis­tance man­ag­ing QFF, con­tact (03) 5871 9222 or gmvfruit­fly@moira.vic.gov.au
