Abstract

The focus of this article is the comprehensive study of the Colorado potato beetle population within potato agro-biocenosis. The research delves into the intricate processes that contribute to the formation and bioecological characteristics of this beetle population. The article also delves into a specific strain known as Beauveria bassiana VTq-28, which was isolated from the Colorado potato beetle. This strain was subjected to testing both in laboratory settings and in the field, targeting various developmental stages of the Colorado potato beetle. The objective was to evaluate the effectiveness of Beauveria bassiana VTq-28 as a biocontrol agent against the beetle. Additionally, the research assessed the insecticidal activity of locally sourced strains of B. thuringiensis against the Colorado potato beetle. This analysis provides insights into the potential of B. thuringiensis strains as another avenue for biocontrol. By thoroughly examining the population dynamics, bioecological characteristics, and the potential of specific microbial agents for controlling the Colorado potato beetle, this study contributes to the understanding of pest management strategies within potato agro-biocenosis. The findings have implications for sustainable agricultural practices and the effective control of this economically significant pest.
