Carrot Root Fly (Psila rosae) can be a severe pest to Carrot crops. The fly is small measuring 5-8mm in length with a black body and yellow head. They have red eyes and pale yellow legs with clear coloured wings. Eggs are laid in the soil surface around the Carrot plants.
Depending on the temperature, these eggs hatch into creamy coloured larvae after about 7 days. The larvae move through the soil to the Carrot plants and start feeding on the roots, eventually burrowing into the Carrot roots forming mines. The first symptoms are a reddening of the Carrot leaves, which start to wilt.
There are normally two generations of Carrot Root fly a year. The first generation appears late April/early May and the second towards late July/August. Carrot Root Fly traps should be in position just prior to these times and throughout these months. The traps will help monitor Carrot root fly populations and reduce the number of egg laying adults by catching them on specially coloured sticky traps, which acts as an attractant.
