This paper reports a series of experiments and commercial evaluation from 1994 to 1996 evaluating the bioefficacy of the aggregation pheromone (ethyl 4 - methyloctanoate) of Oryctes rhinoceros. The aggregation pheromone has been found to be highly effective for mass trapping of rhinoceros beetles, at the optimum density of one trap per 2 hectares. Mass trapping was effective in the reduction of damage at low pest population. It is 31 per cent cheaper in cost and 86 per cent less in labour requirement (comparing to conventional control by carbofuran application). It was effective in trapping large number of beetles in high pest population but palms were still damaged. It can also be used effectively in IPM packages for removal of beetles, monitoring of beetle population and biological control.
