Methods of protection

  • Assess the risks in several ways:
    • by trapping adults;
    • by observing egg-laying and damage, and differentiate between the species of budworm larvae present.
  • Apply insecticides if necessary * ( e-phy ). There are effective ovicidal and larvicidal insecticides which are applied to other budworms, without the need for specific intervention except in Alsace.
  • Preserve the auxiliary fauna because there are many natural predators and parasitoids of A. ljungiana . If the use of insecticides is unavoidable, take into account their absence of unintended effects on the auxiliaries.
