Impact of trapping density on the performance of aggregation pheromone against Rhynchorphorus ferrugineus (Coleoptera: Dryophthoridae)

Red palm weevil (RPW), Rhynchophorus ferrugenius (Coleoptera: Dryophthoridae) is world-wide pest of palms causing severe losses, eventually loss of entire trees. Although, synthetic chemicals are ultimately used for its management, but, aggregation pheromone (Ferrugineol) is widely used for the monitoring and a key component of IPM of RPW. Therefore, this study was conducted in a date palm orchard at district Khairpur, Paksitan to determine the appropriate trapping density that should be utilized for the better monitoring and management of RPW. Three trapping densities i.e., 3, 4, 5 and 6 traps per acre were used in randomized complete block design, where each block was separated by a 1 acre. Each treatment was replicated thrice. Bucket type plastic traps were used where RPW aggregation pheromone (P028 Ferrolure+® ChemTica International, Costa Rica) was attached to the lid of trap. Results obtained indicated that maximum attraction and capture of RPW was recorded at 4 traps per acre density, but not significantly different from 3 traps per acre density. Relatively lower RPW capture was recorded at 5 and 6 traps per acre density. Moreover, traps remained effective for eight weeks after installation. Therefore, RPW aggregation pheromones should be installed at 3 or 4 traps per acre for the better monitoring and management of RPW in date palm orchards, however, level of infestation and environmental conditions may be considered in the decision making.
