During the first two weeks of May 2019, a total of 368 flies were trapped in the 373 traps deployed in the Goulburn Murray Valley (GMV) giving an average of 0.49 flies per trap per week (FTW). There were 268 flies (0.55 FTW) found in rural trap sites (244 sites) and 98 flies (0.42 FTW) in urban sites (117 sites).Typically trap capture rates are higher in urban areas than in rural areas, however as forecast last month, rural rates are catching up with urban rates as more and more fruit become attractive to Queensland Fruit Fly (QFF) in rural areas. However due to the colder days and particularly the cold nights, rural trapping rates are now decreasing. Urban FTW peak, usually, in late September and then again over an extended period from mid-December to late January. Rural FTW, on the other hand, tend to peak over the period from mid-March to early May.
