Effectiveness test entomopathogenic nematodes Steinernema sp. at the coffee berry borer pest (Hypothenemus hampei Ferr.) (Coleoptera: Scolytidae) in the laboratory. The aimed of the research was to determine the effect of application of Steinernema sp. to control H. hampei. This research was conducted at the Laboratory of Plant Disease, Faculty of Agriculture, University of Sumatera Utara, Medan at an altitude of ± 25 meters above sea level, from November 2014 to  April 2015. The research used Complete Randomized Design (Non Factorial) with various nematodes level. They were N0 (No nematode/control), N1 (68 JI / ml), N2 (138 JI / ml), N3 (208 JI / ml). The parameters observed were the symptoms of an attack and the percentage of mortality H. hampei. The results showed that the best result to control H. hampei was showed on treatment N3 (208 JI / ml) with a percentage of mortality by 82 % .
