Theresearch resulted that, the all of insecticide significantly effected the pest of pod Riptortus linearisand Etiella zinckenella. The best treatment to the Riptortus linearis is A2 (Morinda citrifolia seeds200 gr/l) that the lowest attack percentage (10.00%) and Etiella zinckenella is A4 (chlorfiriposinsecticide) that the lowest attack percentage (6,95).Keywords: Riptortus linearis, Etiella zinckenella, insecticide.
