The Order Insecta contains nearly one million described species (May 2000) which comprise approximately 67% of the world's described fauna and flora. Insects are central to the performance of many ecosystem processes. However, it is in their role as herbivores that conflicts arise with agricultural production due to direct consumption of cultivated crops and indirect damage by plant virus transmission or spoilage of potential yield. Natural enemies such as predators, parasitic wasps and flies, as well as pathogens have long been studied for exploitation in biological control and integrated pest management (IPM) strategies. For the purposes of this review, we will concentrate on examples of work with entomopathogenic fungi, which illustrate the principles or strategies which can be used to reduce losses by insect pests.
