Item Assessment of bio‑formulations of indigenous strains of Bacillus thuringiensis, Metarhizium robertsii and Metarhizium majus for management of the rhinoceros beetle, Oryctes rhinoceros L., in field(2023) C. Manjunatha; V. Velavan; R. Rangeshwaran; M. Mohan; A. Kandan; G. Sivakumar; A. N. Shylesha; M. K. Prasanna Kumar; D. Pramesh; M. Sujithra; H. K. Ranganath; S. N. SushilAmong all the coconut pests, rhinoceros beetle causes acute and serious damage to coconut palm. Management of this pest is very difficult due to its nocturnal activity, and also, it damages the emerging leaf inside the bud. Management of rhinoceros beetle using entomopathogens will be of great importance as it is economical and ecofriendly. Studies were carried out to decipher the biocontrol potential of indigenous entomopathogenic bacterium (Bacillus thuringiensis) and entomopathogenic fungi (Metarhizium robertsii and M. majus) against Oryctes rhinoceros in the field, individually as well as in combination, by soil drench as well as by topical spray method.
