Rhinolure is an aggregation pheromone effective in mass trapping both males and females of the coconut rhinoceros beetle. The active compound 4-methyl octanoate serving as an attractant is supplied as bubble formulation in sachets and the chemical is suspended in septa. The trap should be installed at about 5 feet from the ground level and is effective @ 1/ha. The septa can be suspended in the upper lid of the bucket, taking care to avoid direct sunlight as it would be affecting the performance of the lure. The bucket should contain holes and rough corrugations on the lateral sides just below the upper lid so that the beetles that are attracted, alight on this rough surface for entering the holes.
