Biological Methods of Pest Control

Abstract

The establishment of intensive apple orchards in Uzbekistan is a key agricultural policy aimed at increasing productivity and enhancing fruit quality for domestic and international markets. However, pest infestations, particularly from aphids (Myzodes persicae Sulz.), pose a significant challenge by reducing plant vitality and fruit yield. This study examines the effectiveness of lacewing (Chrysoperla carnea) as a biological control agent against aphids in intensive apple orchards in the Samarkand region. Experimental results indicate that lacewing applications at ratios of 1:10 and 1:5 achieved the highest biological efficiency, reducing aphid populations by up to 77.5% during leaf budding and 75.4% during fruiting. The integration of lacewings into orchard management minimizes reliance on chemical pesticides, promoting ecological sustainability by preserving soil and water quality and protecting pollinators. The findings highlight the potential of biological control in reducing pest populations while maintaining orchard health and productivity. Implementing such eco-friendly pest management strategies supports sustainable horticulture development in Uzbekistan.
