Methods of protection

  • Evaluate the risk on the plot by observing the larval populations early in the season. It is sometimes necessary to carry out a treatment in the spring if 80% of the vines are infested with larvae.
  • Apply insecticides if necessary ( e-phy ).
  • Take into account the presence of natural parasitoids, such as trichogramma ( Trichogramma semblidis ) and certain Ichneumonidae ( Pimpla turionellae , Discoelius zonalis , Diadegma fenestralae ). The same will be the case for natural predators such as Anthorocidae bugs ( Orius sp.) And spiders ( Salticidae sp.).
