| dc.description.abstract | Among the insect pests ofcoconut, the red palm weevil Rhynchophorus ferrugineus and rhinocero~ beetle, Oryctes rhinoceros are reckoned as important. Roving survey made in eight coconut growing districts of Andhra Pradesh during the years 2000 to 2008 showed low to medium incidence of rhinoceros beetle in all the districts and severe incidence ofred palm weevil in East Godavari district. This information on relative severity of the two pests was useful to guide in suitable interventions for integrated pest management. Efficacy of pheromone lures of rhinoceros beetle (Ethyl 4-methyl octonoate) and red palm weevil (4 methyl -5 -nonanol) from different sources were tested. There were distinctly high catches of rhinoceros beetle recorded in rhino lure during April, May, June, September and October months, while red palm weevil lures recorded higher catches of weevils in March, April, May, June and July months. Among the sources compared, rhino lure appeared superior for trapping rhinoceros beetle, while the red palm weevil lure from CPCRI, Kayangulam proved superior against red palm weevil. Trapping and destruction ofrhinoceros beetle through pheromone traps resulted in the reduction of leaf and spindle damage by 27.3 and 59.9%, respectively. Use of pheromone trap for red palm weevil was found to effectively reduce the palm damage by 78% and 93% dead palms. | en_US |
