In India, coconut is grown in an area of 1.89 million hectares covering 18 states/union territories the southern states including Kerala, Tamil Nadu, Karnataka and Andhra Pradesh account for 89.7% of total area. Coconut oil also helps in the absorption of vitamins, minerals and amino acids. The saturated fats in coconut oil have antimicrobial properties. Coconut oil finds extensive use in food and industrial sectors because of its unique characteristics. majus are compatible and they seemed to have a synergistic effect in controlling the pest in coconut orchard.Ĭoconut is commonly known as “Kalpavruksha” in Sanskrit language, and to describe its importance, almost all the parts of the palm are economically important. Study also indicated that soil drench method is more promising strategy than topical spray method in managing larval population of the beetles and also confirmed that B. majus is effective in management rhinoceros beetle in coconut orchard. majus showed 52.8 and 57.6% mortality at 5th week in soil drench and topical spray method, respectively. majus showed 44.8 and 40.8% in soil drench and topical spray method at 5th week, respectively. robertsii showed 40.8 and 44% in soil drench and topical spray method at 5th week, respectively. majus showed 24% mortality in soil drench method and 23.2% in topical spray method at 5th week. robertsii showed 24% mortality at 5th week in soil drench method as well as topical spray method. thuringiensis strain NBAIR-BTAN4 showed 24.8% mortality at 5th week in soil drench method and 24% mortality in topical spray method. majus) against Oryctes rhinoceros in the field, individually as well as in combination, by soil drench as well as by topical spray method. Studies were carried out to decipher the biocontrol potential of indigenous entomopathogenic bacterium ( Bacillus thuringiensis) and entomopathogenic fungi ( Metarhizium robertsii and M. Management of rhinoceros beetle using entomopathogens will be of great importance as it is economical and ecofriendly. Management of this pest is very difficult due to its nocturnal activity, and also, it damages the emerging leaf inside the bud.
One of them includes chopping and burning the decayed logs so that the adult beetle cannot make their homes there.Among all the coconut pests, rhinoceros beetle causes acute and serious damage to coconut palm. Many management techniques have been implied to prevent the coconut rhinoceros beetles from destroying coconut trees.Some of the several contributors to this fund included Australia, the United Kingdom, France, Western Samoa, and the United States of America. To eradicate this beetle species in the South Pacific regions, the South Pacific Forum initiated a special fund by the United Nations.Like, it reached Hawaii through an air cargo in 2013 December. It became a global nuance because of its accidental occurrence in certain countries.This results in a v-shaped cut in the leaves or even creating several holes through their midribs. They bore right into the middle of the plant’s crown, drilling through the young fronds. The larva feeds on the decayed matter and does not harm plants or crops, and the maximum damage is done by the adults, as their diet comprises fresh leaves and sap.
