Pests

Duponchelia

This moth can cause damage to a wide range of potted plants, among which the cyclamen.
Be careful: once the pest is well present, it is too late to react!
In its natural environment, the Duponchelia is active from April till October. In France it propagates at the end of spring/ beginning of summer and grows during the summer.
At the beginning, the larva is quite small “like a sciaria” and reaches 2 to 3 cm at its final stage. The adult moths are small with a long abdomen curved upwards.
On young cultures, the larvae attack the region just above the hardly developed bulb and eat it.
Most of the time, the plant manages to produce leaves and therefore it becomes more difficult to discover the larvae. If preventive measures have failed, or if interventions have come too late, one can try to control the larvae.  
How to cure? In fact the efficiency of the actions depends on the right moment. Bacillus thuringiensis Kurstaki, Steinernema carpocapsae, Hypoaspis, lamps or traps, homologated products, etc.
