The pheromone primarily catches the males, who are thus removed from the population development. There is a reduction in egg laying and thus a reduction in the intensity of damage.
Use only in combination with WitaTrap Delta trap or yellow board. Duration of action: 7 - 8 weeks! Pest: Chestnut leaf miner - Cameraria ohridella Occurrence: Chestnuts, predominantly in the leaves of the white-flowering, common horse chestnuts

Main symptoms:
The first small light brown spots appear in mid-May (after budding). on the leaves, which then quickly enlarge.

Biology:
The larva overwinters in the falling leaves. The first generation emerges from the ground at the end of April/beginning of May. The females lay their eggs on the upper side of the leaves when chestnuts are in bloom. The first generation primarily affects the lower crown area. After about 2 weeks, the larvae hatch, bore into the leaf and eat the tissue between the top and bottom. The second generation butterflies fly at the end of June/July. Theoretically there can be up to four generations, but this is often not possible due to premature leaf fall.
Oviposition: female lays approx. 100 eggs
Development time of the larva: approx. 2 weeks
Development time for pupation: approx 2 weeks
Main flight time of the generations: end of April to August (theoretically possible until October)
