Every year in Catalonia, Spain, farmers have to fight the olive fruit flies so they don’t ruin the year’s crop. PHOTO: Wikipedia
The olive fly (Bactrocera oleae) is the single major pest for olives, causing widespread crop damage and significant financial losses to Europe’s olive farmers. The control of the fly has been largely based on the use of chemicals, but the intense use of insecticides leads to development of insecticide resistance, which makes control problematic. In addition, legislation on insecticides have seen some of them being phased out. An alternative? The almost-DIY fly trap.
