    Abstract

    Up to now insecticides are mainly used to control grayak worms. Insecticide can induce negative side efects, as environmental polution. restency and resurgency. The research used Complete Randomized Biok Design. consisting of two factors. the first factor was extraction of Mimba grain. consisting of extraction with Water (A 1) and extradIon with ethanol (A2). The second factor was consentration of Mimba consisting of control (BO). 20 % concemation (B 1). 40 % coooemation (B2). 60 % concentramn (83), 80% conc:erVaion (84) and 100 % concentration (B5). The resu~ of tained showed that extraction of Mimba grain with ethanol could increase the death percentation of the S litura up to 13.89% compare extract of Mimba grain with water which made death percentation of about 10.56%. The fastes death of litura is 15 hour after apllication. Mimba grain extracttion with ethanol and mimba grain extraction with water killed resplectivly 2.7% and 1.11% S Htura.
