The Queensland fruit fly (Bactrocera tryoni) is a significant horticultural pest in Australia, and has also established in other parts of the Pacific. There is genetic evidence that the two species hybridize (Morrow et al., 2000). Pest fruit fly (Diptera: Tephritidae) in northwestern Australia: one species or two? Bactrocera tryoni (Froggatt) (=Dacus tryoni (Froggatt)), Diptera: Tephritidae, Queensland fruit-fly. World Crop Pests [ed.

Canberra, Australia: ACIAR, 138 pp, Weldon, C. W., Schutze, M. K., Karsten, M., 2014. These species have established following introduction in Australia. Mexican fruit fly. In southeastern fruit-growing regions, microsatellites suggest that some of these outbreaks might derive from genetically differentiated populations overwintering in or near the invaded area. B. tryoni has never been found in Tasmania. A great community story, our CFA’s busy January, Chewton’s “eye-in-the-sky”, Castlemaine’s Paddock development, swimming (and sitting) at Chewton Pool, and twenty years of Chatting… yeah! B. tryoni, the Queensland fruit fly, is the most costly horticultural pest in Australia and has invaded several countries in the surrounding region (White and Elson-Harris, 1994). mature larvae should be transferred to sawdust (or similar dry medium) to Using a field site located at the subtropical/temperate interface, with host fruits continuously available, we monitored the development times and abundance of B. tryoni, a species which has invaded temperate Australia from the tropics. Meats, D.C.A. When several references are cited, they may give conflicting information on the status. (2000; see also CABI/EPPO, 1998, No. Most released B. tryoni do not disperse far from their point of origin (~45% <100 m; ~95% < 1 km) (Meats and Edgerton, 2008) and this is consistent with the finding that the spread of incipient populations is also limited to ~1 km (Maelzer et al., 2004). B. tryoni is larger than a house fly (wing length 4.8-6.3 mm). This product can be made cheaply from brewery waste (Umeh and Garcia, 2008). Fruit Flies; their Biology, Natural Enemies and Control. Combined with an insecticide it can be impregnated into small caneite blocks or other absorbent material. Both males and females of fruit flies are attracted to protein sources emanating ammonia, so insecticides can be applied to just a few spots in an orchard and the flies will be attracted to these spots when they get near them during their daily foraging (Bateman et al., 1966 ab; Bateman, 1982).

There is no genetic evidence that the two species hybridize (Gilchrist and Ling, 2006). Many countries that are free of Bactrocera spp., such as the USA (California and Florida) and New Zealand, maintain a grid of methyl eugenol and cue lure traps, at least in high risk areas (ports and airports) if not around the entire climatically suitable area.
