EFFICIENCY AND LONGEVITY OF FOOD BAITS IN PALM WEEVIL TRAPS
Pheromone trapping of RPW is an effective method to manage populations of this palm pest. Current pheromone lures last for 2 to 5 months depending on the season, but the necessary food component lasts only for a week or two. Water evaporation and loss of attractancy are the two main problems with the food component. This paper will present work done on a related species Rhynchophorus palmarm aimed at making the food component of the trap more attractive as well as adding ingredients to the trap to extend the field life of the food. Emission of ethyl acetate from dispensers in pheromone/food traps increases captures compared to pheromone/food traps by 2-5×. Addition of propylene glycol to traps extends the effective life of food in traps. What has not been effective in the field to date is the substitution of attractive blends that attempt to replace food.
