Abstract:
Spodoptera exigua (Hübner), an important insect pest of many field crops, has been difficult to control and eliminated with the pesticide. This study explored the effects of Caesalpinia sappan L. leaf and branch extract on second instar Spodoptera exigua (Hübner) larvae by using the topical application method. The results showed that the leaf and branch extracts have insecticide activities; the ethyl acetate crude extract of leaf, 5,000 milligram per liter (ppm) at 24 testing hours, gave mortality percentage 90 and the dichloromethane crude extract of branch, 5,000 ppm at 24 testing hours, gave mortality percentage: 83.33 The extracts of Caesalpinia sappan L. may be an alternative for natural pesticide against this insect pest.
