Zero burning concepts during oil palm “ to “ oil palm replanting has provided ample breeding and foraging sites for the Oryctes rhinoceros beetles. This study investigated the impact of the different techniques of residue management in oil palm replanting to the abundance of O. rhinoceros. Two types of breeding sites zero and partial burning were selected and the beetle populations were determined between three to 18 months after felling and chipping (MAF). At the sixth MAF different stages of O. rhinoceros were collected from chipped trunks. The results showed that a high population of O. rhinoceros was detected at the 13th MAF; no beetles were detected at the third fourth and fifth MAF from both types of breeding sites. The third instar larvae were recorded as the dominant stage detected during the study. The females were found to be more abundant than the males indicating better food quality and a potential for higher infestation for the coming months. There was no significant differences on the population of O. rhinoceros in both sites. The beetles population tended to increase with MAF. The results of this study suggested that the partial burning of chipped trunks did not decrease the population of O. rhinoceros apart from polluting the environment.

Abstract

Zero burning concepts during oil palm “ to “ oil palm replanting has provided ample breeding and foraging sites for the Oryctes rhinoceros beetles. This study investigated the impact of the different techniques of residue management in oil palm replanting to the abundance of O. rhinoceros. Two types of breeding sites zero and partial burning were selected and the beetle populations were determined between three to 18 months after felling and chipping (MAF). At the sixth MAF different stages of O. rhinoceros were collected from chipped trunks. The results showed that a high population of O. rhinoceros was detected at the 13th MAF; no beetles were detected at the third fourth and fifth MAF from both types of breeding sites. The third instar larvae were recorded as the dominant stage detected during the study. The females were found to be more abundant than the males indicating better food quality and a potential for higher infestation for the coming months. There was no significant differences on the population of O. rhinoceros in both sites. The beetles population tended to increase with MAF. The results of this study suggested that the partial burning of chipped trunks did not decrease the population of O. rhinoceros apart from polluting the environment.
