Abstract

|
To develope a microbial pestiride for the control of agricultural and forestal pests in Korea, the mass culture system of entomopathogenic fungi was studied. Previously, we have developed the mass culture systerm which was adaptable for the culture of Beauveria bassiana. In this study, we determined the efficacy of this mass culture system for other entomopathogenic fungi, B bassiana, Beauveria brongniartii, Metarhizium anisopliae, and Verticillium lecanii. To determine the efficacy of mass culture system, we examined the growth rate of entomopathgenic fungi in this system which was composed of 1st liquid media for growth of blastospore and 2nd pellet media for growth of conidia. As the result, we obtained that the blastospore numbers increased 103 - 104 times in liquid media at 72 hrs post inoculation and the conidia numbers increased about 103 times in pellet media at 3 weeks post inoculation. The result showed that this mass culture system for the growth of entomopathogenic fungi was effective.
