Title : Entomopathogenic Nematode and Insect pest Management: A Review

Abstract :

The entomopathogenic nematodes of the genera Steinernema and Heterorhabditis have capacity to manage insect pests mutually and interact with bacteria of the genera Xenorhabdus and Photorhabdus. These nematodes kill insects within 24 to 28 hours by interacting with their symbiotic bacteria in contrary to other biological control agents that take days or weeks to do so. Entomopathogenic nematodes know to have great insect management potentially and also known safer to non targeted organism and effectively work with their symbiotic bacteria. The biological control agents like fungal bacteria and other micro-organisms require longer time for insect killing. The infective juveniles (IJs) are known to tolerate short-term exposure of various chemical compounds like insecticide, fungicides, herbicides, fertilizers including nematodes and growth regulators and provide opportunity of mass application. They are also known to be compatible with other biocontrol agents under various agro-climatic conditions. The use EPNs can also offer a cost-effective alternative to insect-pest control. Till today only about 12 species out of nearly 182 identified belonging to genera Steinernema and Heterorhabditis have been promoted to be used on commercial level. To help students and researcher understand their activity under field condition and to conduct in depth research on a variety of entomopathogenic nematode relative topics, this article summarises the work carried out in india & abroad integrated pest management systems. Although more research is needed, the use of EPNs can protect agriculture crops from the harm that insects do while having no adverse effects on people, animals, or the environment.
