Abstract
Rhynchophorus vulneratus and Oryctes rhinoceros are two major pests that cause serious damage to coconut palms leading to a significant coconut yield loss. Several pheromones have shown the potential as lures for these insect pests. This study aimed to measure the effectiveness of Oricmas, Rhynchomonas, and Feromonas, the three types of pheromones, against R. vulneratus and O. rhinoceros. In this study, traps baited with each pheromone were installed at the four Research Stations of IPCRI in North Sulawesi, was infected by R. vulneratus and O. rhinoceros.Two locations were selected in each station, and at each location, three traps were installed with different pheromones. The research was carried out from April to September 2020. A total number of 3723 R. vulneratus and O. rhinoceros were trapped during the study. Oricmas pheromone showed the most effective to trap R. vulneratus and O. rhinoceros compared to Rhynchomonas and Feromonas. The number of R. vulneratus and O. rhinoceros trapped was 51.18% and 49.82%, respectively. Rhynchomonas demonstrated its effectiveness to trap R. vulneratus, while did Feromonas to O. rhinoceros. For monitoring and controlling R. vulneratus and O. rhinoceros, Oricmas could be used, while Rhynchomonas and Feromonas for monitoring and controlling Rhynchophorus and Oryctes, respectively.
