Mass Production of Entomopathogenic Fungi, Metarhizium robertsii and Metarhizium pinghaense, for Commercial Application Against Insect Pests

Overview

This study explores the mass production of infective conidia from South African isolates of the entomopathogenic fungi Metarhizium robertsii and M. pinghaense for use in biological control against agricultural insect pests. The findings contribute to integrated pest management strategies amid growing restrictions on conventional insecticides due to environmental and health concerns.
