The result showed that the most effective percentage mortalitywas found in treatment P4 (babadotan 500 gr / litre) (100%), followed by P2 (alamanda 500 gr /litre) (85%), P3 (babadotan 250 gr / litre) (80%), P6 (kamboja 500 gr / litre) dan P8 (mengkudu 500gr / litre) (75%) and less effective was found in P1(alamanda 250 gr / litre) and P5 (kamboja 250 gr/ litre) (45% and 50%). The most effective percentage of Forming pupae was found in P4(babadotan 500 gr / litre) (0%), followed by P2 (alamanda 500 gr / litre) and P3 (babadotan 250 gr /litre) (15% and 20%), and less effective at P1(alamanda 250 gr / litre) and P5 (kamboja 250 gr /litre) (55% and 50%), followed by P7 (mengkudu 250 gr / litre) (45%).
