Some botanical insecticides can be mixed with synthetic insecticides to reduce dependence on one type of insecticide and increase its effectiveness. This study evaluated combined formulations of botanical pesticides (citronella oil/CTO from Cymbopogon nardus and clove oil/CLO from Syzygium aromaticum ) and synthetic insecticide (Cypermethrin 500 EC/Cyp) to improve their effectiveness against Dasynus piperis on pepper plants. This study was conducted in farmer’s fields, Central and West Bangka regencies in Bangka Island, from March 2013 to November 2015. This study consists of two steps; semi-field and field studies. All of the treatments used Randomized Block Design consisted of eight treatments and four replications. The treatments were CTO 5.0 ml l −1 ; CLO 5.0 ml l −1 ; CTO 2.5 ml l −1 + CLO 2.5 ml l −1 ; CTO 2.5 ml l −1 + Cyp 1 ml l −1 ; CLO 2.5 ml l −1 + Cyp 1 ml l −1 ; CTO 1.25 ml l −1 + CLO 1.25 ml l −1 + Cyp 1 ml l −1 ; Cyp 2.0 ml l −1 ; and control. The results showed that CTO, CLO, and Cyp formula was compatible, with CTO 2.5 ml l −1 + CLO 2.5 ml l −1 and CLO 2.5 ml l −1 + Cyp 1.0 ml l −1 were effective to control D. piperis .
