Fruit Fly (Drosophila spp.)
Small vinegar flies attracted to fruit, compost and fermentation by-products.
Drosophila fruit flies breed in fermenting organic matter and overripe fruit. In horticulture they are mostly a contamination nuisance, but species such as Drosophila suzukii (Spotted Wing Drosophila) can cause fruit damage. Cultural controls include sanitation, removal of fallen fruit and dry compost management. Soil predators and nematodes help reduce larval stages in growing media.
Biological Controls for Fruit Fly (Drosophila spp.)
The species below are examples of beneficial organisms commonly used against fruit fly (drosophila spp.). Recommendations are based on published biological control information and practical IPM experience. Always confirm suitability for your crop, growing system and local conditions before use.
General biocontrol + nematodes in soil
Environment: glasshouse
Temperature Range: 16.0 – 30.0°C
Rate: Drench areas with high larval activity at 250k–500k/m²
Frequency: Repeat every 2–4 weeks if needed
Biocontrol options are limited; focus on hygiene, trapping and where appropriate nematode drenches into infested media.
