White grubs are one of the major pests of sugarcane crop in coastal Andhra Pradesh, India. The present study was taken up to assess the efficacy of biocontrol agents viz., entomopathogenic fungi and entomopathogenic nematodes for management of white grub, Holotrichia consanguinea in sugarcane ecosystem during 2015-16 and 2016-17. Two entomopathogenic fungi, Metarhizium anisopliae (NBAIR Ma4 strain) and Beauveria bassiana (NBAIR Bb5a), two entomopathogenic nematodes (Heterorhabditis indica NBAIR-H38 and Steinernema carpocapsae NBAII Sc 05), Neem cake, Phorate 10G were evaluated through soil application as different treatments in white grub infested sugarcane field in coastal Andhra Pradesh for two seasons during 2015 and 2016-17. All biocontrol agent treatments were better than the insecticidal/neem cake application in the management of sugarcane white grubs.However, based on cost benefit ratio of the treatments, soil application of M. anisopliae @ 2.5 kg along with 250 kg farm yard manure per hectare (twice application in July and August) proved superior to other biocontrol agent treatments. Soil application of biocontrol agents, Phorate and Neem cake did not show anydeleterious effect on non-target organisms like, earthworms, earwigs, spiders, coccinellids and chrysopids.
