pest introduction. The most successful way of
controlling and managing the RPW is the use of
the IPM program. It includes monitoring and tak-
ing care of the palm in susceptible age regularly;
trapping adult RPWs using pheromone trap bait-
ed with synthetic pheromone and with synergists
such as yeast-fermented sugar solution, ripened
pineapple pieces, sugarcane stem pieces, or coco-
nut petiole pieces; treating cuts and infections in
palms; detecting the RPW at early stage; treating
the plant in early stages with systemic insecticide
if infected with RPW; eradicating and properly
disposing infested palm or its parts; proper cut-
ting of fronds incorporated with proper agricul-
tural practices and training and educating farmers
and Agriculture Department officers.
