A method for controlling the number of the leopard moth Zeuzera pyrina L. (Lepidoptera, Cossidae) includes spraying of tree crowns with biological preparations. Late in July, at the beginning of mass rebirth of caterpillars of said moth prior to the beginning of penetrating thereof into leaf stalks, double overall spraying of tree crowns with an aqueous solution of the preparation Lepidocide is carried out. In the period of migration of caterpillars of said moth from the leaf stalks for settling tree branches, double spraying of trees with an aqueous solution of the preparation Phytoverm is carried out, and in the period of the beginning of forming the diapausing stages of said moth single spraying with an aqueous solution of the preparation Metarisin is carried out. |
