Abstract

This article presents the results of research on the distribution and damage level of the gypsy moth (Lymantria dispar L.) in forest ecosystems of the Piskent forestry in the Tashkent region. Field observations and entomological monitoring methods were used during the research. The results showed that the pest mainly develops on deciduous tree species, particularly oak (Quercus robur), poplar (Populus nigra) and mulberry (Morus alba). The active feeding period of larvae occurs in May–June, during which defoliation levels in some forest stands reached 30–40 %. A phenological calendar of the pest development was also established. The study revealed that the population dynamics of the gypsy moth largely depend on climatic conditions and the composition of host plants. The obtained results are important for improving forest pest monitoring and developing effective forest protection measures.
