Exploring Indigenous Entomopathogenic Fungi: Ecological Significance and Potential Applications in Rangareddy District, Telangana, India

Abstract

Aims: This study aims to investigate the ecological significance and potential applications of indigenous entomopathogenic fungi in pest management, focusing on the Rangareddy district of Telangana, India. Study Design: The study utilized a combination of the Galleria bait method and direct isolation techniques to collect and isolate entomopathogenic fungal species from insect cadavers and soil samples in various locations within the district. Place and Duration of Study: The research was conducted in the Rangareddy district of Telangana, India, over a specified period. Methodology: Six indigenous fungal isolates, including Metarhizium rileyi, Beauveria bassiana, and Lecanicillium lecanii, were obtained through the aforementioned techniques. The relationship between fungal species, soil pH, and host plants was explored. Results: The study identified the presence of M. rileyi isolates in Mansapally and Aziznagar, B. bassiana isolates in Nagaram and Mansapally, and L. lecanii isolates in Kesaram. Notably, three isolates were obtained through direct isolation from insect cadavers, while three were obtained through the Galleria bait method, indicating the effectiveness of both approaches. Furthermore, the research revealed significant associations between fungal species, soil pH levels, and host plants, highlighting the complex interactions within the ecosystem. Conclusion: This study provides valuable insights into the distribution and ecological relevance of indigenous entomopathogenic fungi in the Rangareddy district of Telangana, India. The findings offer potential implications for sustainable pest management practices, emphasizing the need for further research to validate and expand upon these discoveries.
