This is an article about the managing of fruit flies in Berries in Queensland. Adult Queensland fruit flies (QFF) are about 6–8 mm long and are coloured reddish brown with yellow markings (Figure 1). They are most active in warm, humid conditions and after rain. QFF lay eggs in maturing and ripe fruit on trees and sometimes in fallen fruit. The female fruit fly must feed on a source of protein before her eggs will mature.
