- Abstract
Entomopathogenic nematodes (EPNs) are well-known biocontrol agents to control both above- and below-ground insect pests. EPNs can also control plant parasitic nematodes by releasing allelochemicals through symbiotic bacteria present in their guts. This study aimed to evaluate the bio-efficacy of a novel powder formulation comprising of infective juveniles (IJs) of a heat-tolerant indigenous EPN species of India, Steinernema abbasi, against subterranean termites (Odontotermes obesus) in wheat and chickpea fields. The bioefficacy of test formulation in field study for three rabi seasons (2020-2023) in wheat and chickpea grown in field heavily infested with subterranean termites decreased the plant damage from termite attack, monitored as relative number of infested tillers in wheat and infested plants in chickpea fields. The reduced damage in test crops caused by termites increased growth, yield attributes and yield of test crops. This present research validated the prepared formulation's potential as a biopesticide ideal for organic farming and integrated pest management practices.
