Notes: Insect pests with limited distribution, including Hyphantria cunea, Grapholita molesta and Quadraspidiotus perniciosus [Diaspidiotus perniciosus], are the main quarantine pests in the Ukraine. Fruit trees are also attacked by Pseudococcus comstocki. However, the latter does not have practical importance for commercial plantations. Information is included on distribution, damage to host plants and life cycles of the main quarantine insect pests. Data are tabulated on the use of pheromone traps and insecticides, and a recommended scheme for the protection of apple orchards from combinations of quarantine pests.
