Over the past 10 years, farmers of Uttaranchal and western Uttar Pradesh, India have been fighting a losing battle against the white grub (Coleoptera: Scarabaeidae) infestation of sugarcane crop. Pesticides have failed to address the problem as evident from the observed infestation levels of 10-24 grubs/m2. During 2008-2014, the Division of Nematology, Indian Agricultural Research Institute, New Delhi launched a biocontrol project involving treatment of the white grub-afflicted fields with entomopathogenic nematodes (EPNs)-infected Galleria mellonella cadavers. This initiative, spread over the districts of Ghaziabad, Meerut, Amroha, Saharanpur, Gajraula, Bulandshahar and Hapur, was undertaken in collaboration with a non-governmental organization - the Foundation for Resources Management and Environmental Remediation - and local sugar mills, and by enlisting the active participation of the farming community. It was perceived that this technology had a greater possibility of evolving into a long-term, sustainable biocontrol strategy if the EPN-infected Galleria were sourced in each village. Capacity-building programmes were undertaken in the villages with special focus on empowering women, and small and marginalized farmers by educating them on rearing and infecting Galleria. This initiative has resulted in an average reduction of 69.1% in the white grub population and an average increase of 60.49 q/acre in sugarcane yield over untreated control.Keywords
