Using Your Carrot Root Fly Trap
The trap is made from orange plastic with the surface covered in sticky glue. The colour of the trap helps attract the carrot root fly adults onto its sticky surface where they are caught. The trap is also positioned at an angle shown to further enhance the catch rate of the trap. The trap is supplied with a field pole, fixing clip and 5 orange sticky boards. The traps should be placed around the edges of raised or open beds where carrots have been sowed and should in place by the time the first carrot seedlings emerge. Once the traps are full of insects or if they get covered in dirt or dust, replace the sticky traps with new boards. 5 are supplied with the product and refill packs are available.
Carrot Root Fly Appearance and Lifecycle
Carrot root fly (Psila rosae) is about 8mm long with a red to brown head. The body is black and similar to ant with wings. The female adult carrot root fly lays eggs in the soil beside the plants it attacks. The first eggs are laid in April-May from adults that have emerged from over-wintering pupae. There are normally 2-3 generations per year. The eggs hatch into larvae in about 7 days. The second generation appears through July and August.
Symptoms and Damage
The carrot root fly larvae feed on root hairs and then burrow into the stems and roots of plants. Seedlings and transplants are very vulnerable to attack. Carrot root fly attack carrots, parsnips, celery and parsley. First symptoms are a reddish tinge to carrot leaves appearing and plants wilting. The creamy coloured larvae of the carrot root fly burrow into roots and allow secondary rots to get into the carrots.
