Entomopathogenic Nematodes in Pest Management

Naturally occurring entomopathogenic nematodes and their symbiotic bacteria are important biotic factor in suppression of insect pest populations in soil and cryptic habitats. The virulent species of these nematodes are commercially produced as biological control agents all over the world encompassing North America, Europe, Asia and Australia in glasshouse crops, orchards, ornamentals, turf, lawn, and forestry. India has a great potential to exploit these beneficial nematodes for the suppression of insect pests. Recent emphasis on mass production and formulation technologies of these nematodes in India stresses a need to implement safer and effective pest control methods. This article provides an overview of recent development on formulation and commercialization of entomopathogenic nematodes, and evaluates their potential exploitation in India.
