Application of innovative biological agents for sustainable corn farming

Abstract

Corn, being the most important crop globally, requires effective protection against pests while maintaining environmental sustainability. This study focuses on the development of environmentally friendly methods for biological control of major corn pests. The research investigates the combined use of pheromones, entomopathogenic preparations, and parasitic Hymenoptera, such as Trichogramma evanescens West and Habrobracon hebetor Say, to combat pests. The seasonal dynamics and abundance of cotton moth (Helicoverpa armigera) and click beetle (Athous tauricus) were monitored using pheromone traps. The number of corn moth (Ostrinia nubilalis) caterpillars was recorded, and mass breeding of the ectoparasite Habrobracon hebetor was conducted for biological control. The effectiveness of the integrated approach, combining entomophages and biological preparations, was evaluated. The study demonstrates satisfactory effectiveness in biological protection, with significant reductions in corn moth and cotton moth populations. These findings highlight the potential of environmentally friendly techniques for pest control in corn crops, contributing to sustainable agricultural practices.
