- A study aiming at comparing the effectiveness of seed extract of Phaleria papuena Warb andchemical insecticides for controlling beet armyworm pest (Spodoptera exigua Hubner) at the onioncrops has been conducted. The experiment was set up by using a completely randomized design(CRD) with five treatments and tree replicates. The treatments applied were: without insecticideapplication as a control (P0), botanical insecticide, Phaleria papuena extract 2% (P1), 4% (P2), and6% (P3), and chemical insecticide, prevathon 50 SC (P4). Variables measured were Spodoptera exiguapopulation density and intensity of pest infestation. Results showed that application of botanicaland chemical insecticides significantly reducing the population density and the infestation ofSpodoptera exigua. Effectiveness of Phaleria papuena extract 6% (P3) and prevathon (P4) was notsignificantly different in controlling Spodoptera exigua. In average, the application of Phaleria. papuenaextract 6% (P3) and prevathon (P4) reduced population density at 9.4% and 9.3%, respectively, andinfestation intensity of Spodoptera exigua 37.8% and 36.7%, respectively. These results suggestthat the seed extract of Phaleria papuena is highly potential to be developed as botanical insecticide.Key Words: Botanical insecticides, Phaleria papuena, Spodoptera exigua
