O‘RMON BIOTSENOZIDA LEPIDOPTERA TURKUMI BIOEKOLOGIYASI, TROPIK TARQALISHI

Abstract

The article analyzes the bioecological characteristics, population structure, trophic relationships, and dominance levels of phytophagous insects belonging to the order Lepidoptera in forest biocenoses of Uzbekistan. As a result of scientific observations, 19 phytophagous species were identified in the forest biocenosis, of which 10 species were recorded as forming highly dominant populations.

The ontogenesis of Lepidoptera representatives, characterized by complete metamorphosis, and their phytophagous activity during the larval stage were evaluated in terms of their impact on plants within the biocenosis.

The study also revealed the presence of 24 species of entomophagous organisms that naturally regulate phytophagous insect populations, and their role in maintaining biocenotic balance was scientifically substantiated. In addition, the bioecological features of endobiont species—feeding within tree trunks and undergoing their main developmental stages there—were investigated, including their life cycle, generation duration, and population dynamics.

The obtained results reveal ecological relationships between forest and agrobiocenoses, as well as mechanisms of migration and adaptation of phytophagous insects. The findings are of significant scientific importance for ensuring the stability of forest biocenoses, conserving biodiversity, and developing theoretical frameworks for the natural regulation of phytophagous insect populations.
