Entomopathogenic nematodes as bioinsecticides – a review

Abstract

Entomopathogenic nematodes (EPNs) belonging to the Heterorhabditis and Steinernema genera provide effective bio-control of insect pests. They are extremely lethal to such pests due to mutualistic association with the genera of bacteria Photorhabdus and Xenorhabdus and are safe for beneficial insects. They are used as biopesticides because they are eco-friendly with no harmful effects on human wellbeing. EPNs are well-suited with the number of agrochemicals and a cost-effective substitute for chemical insecticides. This review assesses the use of EPNs under agroclimatic conditions, the influence of abiotic factors, life cycle, trapping, production, storage, mechanisms, biopesticides and their suitable application. However, a previous study on EPNs and their role as biopesticides have been surveyed for their possible usage as biological control agents.
