The good news is that only two of them - the Queensland fly on the east coast and the Mediterranean fly on the west coast are problems for gardeners. There are over 250 species of fruit fly in the family Tephritidae which occur in Australia but only about ten are pests. If you know your compost is balanced between brown and green, consider going on the offensive and trapping the bothersome insects. It is 5-7mm long. tyroni. Females prefer to lay their eggs in fruit that is sweet, juicy, and not acidic. Queensland fruit fly is different from the small dark brown drosophila flies (also called vinegar flies or ferment flies) that loiter around ripe and decaying fruit. ", "Economic Fruit Flies of the South Pacific Region: R. A. I. NSW DPI, Gosford Horticultural Institute. Do not carry fruit at any time into the Fruit Fly Exclusion Zone. Queensland fruit flies (QFF) pose a biosecurity threat to fruit production in New S outh Wales (NSW). [2] Adults hold their wings horizontally when walking and flick them in a specific, characteristic manner. Eggs hatch into white larvae in 2–4 days under favorable weather conditions. 1978. [2] Although B. tyroni have a minimum temperature requirement for survival, extreme plasticity and adaptation has been observed in adult B. Effective management of Qfly ensures producers can develop, maintain and enhance access into domestic and international markets. At this point, the fruit has likely fallen to the ground. You can purchase fruit fly traps at home supply stores such as Home Depot, at major grocers, or online. https://www.interstatequarantine.org.au/travellers/quarantine-zones [2] Despite this behavioral difference, B. neohumeralis and B. tyroni are nearly genetically identical: the two species are only differentiable based on newly-developed microsatellite technology..[6] The evolutionary relationship between the species within the B. tryoni complex is unknown. [2] The killing mechanism often involves pesticides, liquid traps in which the pest drowns, or sticky traps that the pest cannot escape from. The following is a quick guide to identifying (Refer Figures 1-3), monitoring and managing Queensland fruit fly. [2] All of these flies are sympatric, meaning that they inhabit the same territory, except B. aquilonas, which inhabits a different geographical area in northwest Australia. [2], Both male and female B. tyroni require proteins produced by bacteria found on the leaves of plants in order to reach sexual maturity. [19] This behavior, combined with global warming, indicates that damage due to these insects will continue to increase as the temperatures continue to rise. B. tyroni have evolved to disperse widely, which was greatly influenced their ability to cause damage to farms. These larvae, or maggots, eat toward the center of the fruit with their cutting jaws, causing it to rot. tyroni. Other Names: Bee Netting, Fruit Fly Net, #X $ … While these pests can be challenging to control, a successful strategy doesn’t need to be complicated, it just takes a committed approach throughout the year. Of Peaches and Maggots, The Story of Queensland Fruit Fly. Control efforts include submerging post-harvest fruit and treating fields of fruit trees with the chemicals dimethoate and fenthion. Central Darling Shire is the largest Shire in NSW and yet has the smallest population. [9], After passing through a two week pre-oviposition stage following emergence from the pupae, adult females deposit around seven eggs in a fruit puncture, and may deposit up to 100 eggs per day. The larvae then hatch and proceed to consume the fruit, causing the fruit to decay and drop prematurely. Both species have similar host plants, including citrus, loquats, stone fruits, apples, pears, avocados, bananas, mangoes, guavas, feijoas, tomatoes, eggplants and capsicum. Abide by interstate quarantinerules to prevent the spread of Queensland fruit fly and Mediterranean fruit fly. [21] A specific cue-lure, Willson's lure, was found to be incredibly effective at attracting sexually mature B. tyroni males. Body color is usually a light yellow to tan color. [2], B. tyroni prefer humid and warm climates. [25] One such strain of a genetically compatible fly has been developed in Drosophila melanogaster. Industry Leader, Citrus, NSW DPI, Gosford Horticultural Institute. Up to 40 larvae can be reared from a single piece of fruit. [9], Farmers in effected regions are encouraged to use a lure and kill tactic to combat the presence of B. As of October 2011, the use of these chemicals was under review by the Australian Pesticides and Veterinary Medicines Authority. Yes, the Queensland fruit fly has caused many a heart-ache in backyards across Australia. Male B. tyroni respond most greatly to the lure in the morning, likely because this is their peak of foraging time; however, an evolutionary reason for the cue-lure is not fully known. Based upon recent studies which utilize computer programs to simulate B. tyroni distribution in the event of rising temperatures, it was predicted that there will be an overall increase in Queensland fruit fly damage, but the fruit flies will re-localize to more southerly locations as northern and central Queensland will begin to exceed the maximum habitable temperature of B. This is pertinent to control efforts because it is one of the few characteristics that distinguish it from sister species, B. neohumeralis, which are not a highly destructive species, even though the two are very closely related genetically and evolutionarily. [17] Two of the most common lure and kill approaches for B. tyroni are the male annihilation technique (MAT) and the protein-bait spray (PBS). Signs with "Fang the fruit fly", warn you when you are approaching the Fruit Fly Exclusion Zone. [25] Development of a genetically engineered B. tyroni strain that is compatible with gene transfer was successful; however, scientists have yet to develop a sterile strain that can be released into the wild. But Biosecurity SA says the new national Sterile Insect Technology (SIT) facility at Port Augusta is on a much bigger scale and incorporates the latest research. Until now sterile Queensland fruit flies were reared in a small facility at Camden in NSW. It is illegal to take fresh fruit into the Fruit Fly Exclusion Zone without a permit.
