The Acacia mellifera (Vahl) Benth, (family Mimosaceae); namely kitr in Arabic, is a multipurpose tree in Sudan. The economic damage is often difficult to judge due to no enough research attention, moreover, the ecological knowledge is still scarce. Due to lack of forest entomology information of some Acacia species in Sudan, including the mellifera, the current objectives of this study are to characterize the infestation of Acacia mellifera by the insect's pest under study severely infesting other Acacia. Thus, a field study that was conducted in May-July 2007 in Kordofan region (Sudan) to assess infestation characteristics depending on the methods of sampling insects from trees and the insect damage and sign categories described by some investigators and tree measurements triggering infestation (e.g. crown size, and diameter, tree age, and height, and diameter at breast height). The results indicate the presence of holes of infestation in all directions of the tree trunk, with the exception of the north direction. Infestation rates ranged from zero to 26.68% on the study sites (n =2). It could be recommended that longhorned beetles need more ecological research.
