Characteristics of development and damage of Stictocephala bubalus f. in Verishen community of Syunik marz

Abstract

The geographical location of the Syunik region of the Republic of Armenia, the global warming of the climate, the presence of fodder plants have ensured the survival, reproduction and territorial settlement of Stictocephala bubalus F., in new, more southern settlements. As a result of our research in 2019-2021, in the orchards of Verishen community of Syunik marz, we have registered the harmfulness of Stictocephala bubalus F., which is located at an altitude of 1645- 1650 m. At the initial stage damage was observed on several cultivated fruit species, and later to wild species.The pest damages the trees both during feeding and during spawning, causing cuts. In Vernashen Stictocephala bubalus F. mostly damages pears and apples from fruit trees.
