The method of this researchwas Completely Randomized Design Non Factorial with seven treatments, M0 (control), M1 (2gram MNPV/ litre of water), M2 (Bacillus thuringeensis with concentration 7.5%), M3 (neem leafextracts with concentration 4%), M4 (Forficulla auricularia three pairs), M5 (insecticidedeltametrin with concentration 3%) and M6 (insecticide dimetoat with concentration 1%)respectively with four replications. The parameters are the percentage of mortality, symptoms deathof pests and time death of pest. The result showed that insecticide deltametrin most effective thanthe others with percentage of mortality 100% at 4 days after application. The fastest time death ofimago was 1.63 day after application with symptoms body of S. asigna was white like milk
