The study found that this agricultural pest, a significant threat to stone fruit trees, develops in one generation annually with diapause occurring during pupation. Unlike previously assumed, its flight dynamics exhibit distinct seasonal and daily patterns: a single peak in spring and two peaks in summer, influenced by temperature variations. Conducted over five years (2017–2021) on stationary fields, the research employed standard entomological methods for species collection, identification, and data analysis. These findings provide foundational insights for refining pest control strategies in this UNESCO-listed region.

Shaybani Khan's cultural identity and architectural policies in Samarkand at the beginning of the 16th century reveal a distinct departure from Timurid traditions. Unlike his predecessors, Shaybani Khan emphasized Turkic language and theological issues, blending elements of Dashti Kipchak memorial architecture with Bukhara's funerary structures. His construction of the Shaybani Khan Madrasah, near Sarai-mulk Khanum's madrasah, symbolized both legal and theological centralization, while avoiding the opulence seen in Timurid mausoleums. The study, based on 16th-century Central Asian, Persian, and Turkic historical works alongside archive materials, highlights Shaybani Khan's role in adapting cultural traditions to Timurid society while continuing Timurid garden and park construction practices.
