Studies on the safety of selected insecticides to common predators of rice pests brown planthopper to prove of negative effects issues of insecticides on natural enemies. Various methods have been used to measure the effect of insecticides on natural enemies, one of them semi-field studies. The research was carried out in the wet season of 2014 at Subang district of West Java; Indonesia used randomized block design with 10 insecticides treatment (9 insecticides and 1 control) with 3 replications. The results showed that insecticides toxicity of chlorantranilprole + thiamethoxam SC 300, chlorantraniliprole+ abamectin 063SC, pymetrozine, cyantraniliprole + pymetrozine 60WG, lufenuron, abamectin, emamectin benzoate, deltamethrin, and profenofos to Paederus fuscipes and Lycosa pseudoannulata that belong to category 1 were harmless with mortality rate less than 25%. In the persistence test, all insecticides belong to category 1 are short-lived persistence less than 5 days with mortality rate of P. fuscipes and L. pseudoannulata less than 25%. Base on insecticides toxicity and persistence tests showed that all insecticides treatment are safe to P. fuscipes and L. pseudoannulata.
