Field trapping of Rhynchophorus palmarum (L.) using aggregation pheromone and sugar cane as baits

In this work, the efficiency of three different trap designs baited with the synthetic aggregation pheromone (Rhynchophorol) and sugar cane to capture Rhynchophorus palmarum (L.) was evaluated. The 100 L plastic basket trap baited with sugar cane plus the pheromone was the most efficient one. The poor results obtained with traps baited with the pheromone lures alone showed the need of adding a plant kairomone source to the pheromone to obtain higher captures of R. palmarum. This is the first report on the use of Rhynchophorol in Brazilian palm oil plantations.
