RPH Maribaya, BKPH Parung Panjang, KPH Bogor is an Industrial Forest Plantation dominated by A. mangium stands. The information about the characteristics of A. mangium stands that are attacked by pests and diseases is important to manage A. mangium plantations better. The characteristics of A. mangium stands that are attacked by pests and diseases, is done by determining the frequency and intensity of pest and disease attacks on A. mangium stands with some of the symptoms of pests and diseases found in these stands. This research was conducted at Site 23B, RPH Maribaya, BKPH Parung Panjang, KPH Bogor. The methods used in this research is referring to the Criteria and Score for Plant Pests/ Diseases (Mardji, 2000). The results of this research are indicating the highest attack frequency on A. mangium is in plot 4 which is 80% and the lowest is in plot 7 which is 0%. The highest attack intensity is in plot 4 which is 50% and the lowest is in plot 7 which is 0%. The percentage of attack frequency ranges from 20%-80% (low category) with an average percentage of attack frequency of 41%. The percentage of attack intensity ranged from 20% - 50% (mild category) with an average precentage of attack intensity of 23%. some of the pests found in A. mangium stands are sac caterpillars (Pteroma plagiophleps), and the larva of white grub (Lepidiota stigma). The effective pest control measures are taking care of plants that begin in 1-year-old plants and the use of systemic insecticides in the early nursery phase to minimize the attacks.
