Abstract

ABSTRACT: Entomopathogenic fungal species from the genera Beauveria, Metarhizium and Lecanicillium are important components in biological control of insect pests. However, temperature, humidity and UV radiation are among the important abiotic factors, which limit their effective usage. In this study, four local isolates of Metarhizium were isolated from different crop rhiospheres of Telangana and Andhra Pradesh states of India, identified and tested for their temperature tolerance in terms of radial growth, conidial yield per 10 mm disc and rate of conidial germination at different incubation temperatures. The results revealed that strains LaMa1 and MaAICRP performed well in terms of radial growth, conidial yield and rate of conidial germination, even at 35°C temperature. The role of such temperature tolerant strains in agriculture is discussed.
