Abstract

The black twig borer, Xylosandrus compactus (Eichhoff) (Coleoptera: Scolytidae), is one of the few ambrosia beetles that infest healthy plants is a serious pest of coffee. The objective of this study is to determine the intensity of X.compact attacks during the dry season. The results of the analysis of the intensity of the coffee branch borer (X.s compactus) attack on coffee plants in Bonto Tenga village, Sinjai Borong sub-district, Sinjai district were included in the mild category valued at 9.68%, however, the area of the pest attack was quite high at 41.67%. so that if this pest is not suppressed it can cause high yield loss and even the coffee plant cannot grow again due to serious attacks. The mean number of holes drilled per observation was 0.52 and the mean length was X. compact,0.91 cm. That pest attack intensity which is included in this mild category can be caused by several factors, namely humidity and rainfall, shade plants, differences in clones (genetic factors), and the application of side grafting technology.
