Swede Midge
Scientific Name
Contarinia nasturtii
Description
Swede Midge is a tiny fly that infests swede and other brassicas, where its larvae feed within plant tissues, causing distortion, curling, and stunted growth.
Characteristics
These minute flies are barely visible to the naked eye. Their larvae tunnel within leaves and stems, leading to deformed and weakened plants.
Control Methods
- Organic sprays: Apply insecticidal soap or neem oil early in the infestation to curb larval development.
- Cultural practices: Practice crop rotation and interplant with repellent species to disrupt the midge lifecycle.
- Preventive methods: Monitor brassica crops closely and maintain healthy plants with balanced watering and fertilization.
- Biological controls: Introduce parasitic wasps and predatory insects that specialize in midge larvae control.
- Mechanical physical: Use fine mesh netting to protect crops during high-risk periods and remove infested tissues promptly.
Natural Enemies
- Parasitic Wasps
- Predatory Insects
