Background and Objective: The use of pheromones has been instrumental in increasing the effectiveness of both monitoring insect populations and in providing adequate information to enable implementation of cost effective control. Field trials were conducted at Okomu oil palm field, Uhiere, Edo state, to test the efficacy of pheromone traps against Rhynchophorus phoenicis. Materials and Methods: About 3 L bucket traps containing 9 mg/day Rhynchophorus phoenicis pheromone enhanced with pineapple, impregnated with 20 mL insecticide (Cypermethrin) and a control bucket (with only 300 mL water) were set up. In the pre-pheromone assessment survey, fields K, I and H were observed to have been attacked by Rynchophorus phoenicis. Observations were made once a week for 6 weeks after pheromone application. During the pheromone treatment period under review, adult Rynchophorus phoenicis trapped were a total of 169. Results: Mean total distribution per trap of adult R. phoenicis during the study period was 5.63. Week 2 had the highest number (42) of trapped insects, while week 1 had the lowest tapped insects (17). The control trap without pheromone caught nothing. The p-value of the analysis of variance (0.70) indicates that there is a significant difference (p>0.05) among the fields in the number of adult R. phoenicis collected due to the pheromone treatment. It was observed that fields H and I had the highest distribution of R. phoenicis. This implies that more attention should be paid to these fields. Other insects trapped include butterflies, beetles, grasshoppers and wasps. Conclusion: This study confirms the effectiveness of pheromones for control of the adult Rynchophorus phoenicis. This is with minimal insecticidal use and maximum benefit to the palms and environment.
