If one adult fe­male mates with one adult male she can lay up to 2,000 eggs in her life­time, which is about 2 months in the warm weather. From these eggs she could pro­duce 800 ma­ture adult QFF of which ap­prox­i­ma­tively half are fe­male. If con­di­tions are ideal, these 400 fe­males are again ready to re­pro­duce pos­si­bly within 4 to 6 weeks. This is why QFF pop­u­la­tions can ex­plode dur­ing sum­mer and au­tumn.

Re­moval of Un­man­aged Queens­land Fruit Fly (QFF) Habi­tat

Un­man­aged habi­tat is the sin­gle big­gest is­sue pre­vent­ing the Goul­burn Mur­ray Val­ley (GMV) from be­com­ing an Area of Low Pest Preva­lence and de­lay­ing the re­gion’s readi­ness for the re­lease of ster­ile male QFF’s. To date the GMV Fruit Fly Project has re­moved over 2,100 un­wanted fruit trees from res­i­den­tial prop­er­ties. The project has iden­ti­fied nearly 10,000 un­man­aged QFF host trees and plants on pri­vate and gov­ern­ment lands that are cur­rently be­ing ac­tioned for re­moval and erad­i­ca­tion. Ap­prox­i­mately 250 ha of un­man­aged or­chards have also been iden­ti­fied in the GMV re­gion. The GMV Re­gional Fruit Fly Pro­gram can as­sist in the re­moval of fruit trees from un­man­aged or­chards — strict con­di­tions apply. The process for re­mov­ing the un­man­aged or­chard is as fol­lows: • Or­chardists will vol­un­teer their prop­er­ties for tree re­moval; • The prop­erty will be as­sessed by a tech­ni­cal ex­pert and ev­i­dence col­lected that demon­strates a de­clared pest was present at a level in­dica­tive of an un­man­aged prop­erty and could pose a risk to neigh­bour­ing com­mer­cial prop­er­ties. This pest could in­clude but is not lim­ited to fruit fly. The ab­sence of a de­clared pest dis­qual­i­fies the or­chard/ vine­yard from tree re­moval un­der this pro­gram; • Grow­ers will pro­vide ev­i­dence that the or­chard busi­ness is un­vi­able, which would be de­fined as with­out pro­duc­tion from the or­chard blocks for two con­sec­u­tive fruit sea­sons; • Grow­ers will be re­quired to pro­vide writ­ten con­sent to the tree re­moval, con­firm their prop­erty is pre­pared for con­trac­tors and en­sure all in­fra­struc­ture such as wires and trel­lis will be re­moved prior to the en­try of con­trac­tors; • Agri­cul­ture Vic­to­ria will as­sess each ap­pli­ca­tion for or­chard re­moval. The ap­pli­ca­tion will in­clude the sig­na­ture of the per­son re­quest­ing re­moval and data around how many hectares etc; • Agri­cul­ture Vic­to­ria will review and pro­vide fi­nal sign off prior to or­chard re­moval. Or­chardists who can meet all of these re­quire­ments and are in­ter­ested in ap­ply­ing should con­tact the GMV Re­gional Fruit Fly of­fice by phon­ing (03) 5871 9222 or email­ing gmvfruit­[email protected]
