ApproximateIy 1.000 species of insects are associated with coconut worldwide. Over 40 species of coleopteran pests have been recorded - most are under effective natural control but some require interventions. In view of the increasing and devastating damage by coconut beetle (Oryctes rhinoceros) to coconut palms in the many countries, many efforts are made to find appropriate method to forecast its population. The basic procedures of these monitoring programs are outlined together with forecasting method. A study to forecast coconut beetle population has been carried out in palm oil estate, near Palembang. Study is aimed to forecast population after several beetle population observations. Another aim was to assess the influences environmental factors, e.g. temperature, relative humidity, rainfall intensity, which could affect on the beetle population fluctuation. Results showed that beetle population could decline up to 70 % due to unsuitable environmental factors. At first observation temperature was recorded 26 - 30 centigrade and 1085 larvae were found. At last observation larvae population decreased to 392 at temperature 29 - 33 centigrade. It was found that relative humidity and rainfall intensity also played important role in decreasing beetle population.
