TRIXOGRAMMA (TRICHOGRAMMATIDAE) TURLARINI BIOEKOLOGIYASI

This article analyzes the bioecology, life cycle, characteristics, and application of Trichogramma (Trichogrammatidae) species as biological control agents under the conditions of Uzbekistan. The article examines the effectiveness of Trichogramma species, methods for their laboratory rearing and release, and challenges associated with bioecological factors such as climate. The research results indicate that Trichogramma species are effective in the natural control of pest populations within agroecosystems. In particular, the bioecology of Trichogramma evanescens, Trichogramma chilonis, Trichogramma brassicae, and Trichogramma dendrolimi was studied, highlighting their effectiveness in parasitizing the eggs of Lepidoptera and their role in agroecosystems. The average biological efficacy of the above-mentioned Trichogramma species was found to be 75–80%.
