Carrot worm pheromones

Carrot root fly: egg-laying and development

After spending the winter in hibernation as a pupa, the flies appear in May. They generally have two activity cycles from May to July and sometimes a third in autumn in certain regions. They mate and then lay eggs in the soil near the plants they prefer. The larva (Psila rosae), responsible for the damage, will hatch after 10 to 12 days. From the soil, it makes its way to the carrot and enters the root, which it feeds on by digging tunnels. After a month, at the end of its development, the larva leaves the root and settles in the nearby soil to spend the winter as a pupa.

The fly responsible for carrot root fly damage

The fly, once fertilized, lays eggs in the soil near the plants they prefer. The larva that hatches penetrates the carrot where it develops, causing damage: bitter taste, rotten flesh, slowed growth.

How to use pheromones?

Pheromones are volatile substances secreted by females. They play a role in sexual attraction for males. Each species emits a specific pheromone. This makes it possible to trap each type of harmful insect very precisely and very effectively. Pheromones are tools for detecting and controlling populations with high trapping capacity.
