Hi Djamel I agree with diagnosis by Samira Ghouil سميرة غويل Check if there is anything likeFall Armyworm Also looks like helicoverpa zea Please click on the above green hyperlink to get more info 🙂🙂

Sa peux infecter les cerisier ??

Armyworms are caterpillar pests of grass pastures and cereal crops. They are the only caterpillars that growers are likely to encounter in cereal crops, although occasionally native budworm will also attack grain when underlying weed hosts dry out. Armyworms mostly feed on leaves, but under certain circumstances will feed on the seed stem, resulting in head loss. The change in feeding habit is caused by depletion of green leaf material or crowding. In the unusual event of extreme food depletion and crowding, they will "march" out of crops and pastures in search of food, which gives them the name "armyworm". Control There are a number of chemicals registered for control of armyworms. For winter outbreaks (during tillering), economic thresholds of 8 to 10 larvae per m2 provide a guide for spray decisions. For spring outbreaks (during crop ripening) spraying is recommended when the density of larvae exceeds 1 to 3 larvae per m2 although this figure must be interpreted in the light of: timing of harvest, green matter available in the crop, expected return on the crop, and larval development stage (if most are greater than 35-40 mm or pupating, it may not be worth spraying). If spraying is necessary, it is highly recommended that this be carried out in late afternoon or early evening for maximum effect, as armyworms are nocturnal feeders.
