Sažetak
The use of fruit-propagated planting material is vital for the fruit market, but unclear phytosanitary conditions can cause significant losses. Bulgaria and other EU countries comply with high standards for producing fruit trees. Protected tree fruit cultivation is a promising alternative using sustainable practices to improve fruit quality and tree health. New information has been obtained on the development of the San José scale, Diaspidiotus (Quadraspidiotus) perniciosus Comstock, in protected facilities. Using infested propagating material causes greater damage to plants compared to the migration of the species. The harmfulness of the pests was high, and there was an extreme risk of infestation when using nets to produce planting material. The San José scale's harmfulness in apple fruit (Malus domestica Borkhausen) was found to be significantly higher in the insect-proof net house at 75.0%. In the shaded field, this coefficient was 71.7%, and in the non-shaded field, it was 56.7%. Strict measures to limit the spread of the pest have been effective in reducing its harmfulness, offering a sense of control and optimism in managing this issue.
