Botanical insecticides are potential alternatives for the control of <em>C. pavonana</em> pest. Insecticidal activity of<em> Piper aduncum</em> and<em> Sapindus rarak</em> fruit extracts as well as their mixtures was evaluated against <em>C. pavonana</em> larvae in the laboratory. Ethyl acetate <em>P. aduncum</em> (EtPa) extract as well as methanolic<em> S. rarak</em> (MeSr) and aqueous <em>S. rarak</em> (AqSr) extracts were tested separately and in mixtures against second-instar larvae <em>C. pavonana</em> by a leaf-residue feeding method. At the LC95 level - 72 hours after treatment (HAT), EtPa extract was about 14.5 and 12.8 times, respectively, more toxic to <em>C. pavonana</em> larvae than MeSr and AqSr extracts. At the LC95 level, EtPa + MeSr extract mixture (1 : 10 w/w) was about 1.64 times more toxic to the test larvae than EtPa + AqSr extract mixture (1 : 10 w/w). Based on combination index at 48, 72, and 96 HAT, EtPa + MeSr extract mixture at LC50 level as well as EtPa + AqSr extract mixture at LC50 and LC95 levels had additive joint action, whereas EtPa + MeSr extract mixture at LC95 was weakly synergistic. In addition to lethal effect, the treatment with all test materials delayed the development of <em>C. pavonana</em> larvae from second-instar to fourth instar.
