SEBAGAI INSEKTISIDA NABATI TERHADAP LALAT BUAH (BACTROCERA CARAMBOLAE) %X Bio insecticide is a safe alternative to use in controlling insect pests including B. carambolae. The purpose of this research is to determine potential of essential oils leaves basil (Ocimum basillicum) as bio insecticide concerning Bactrocera carambolae. This research using completely random design ( RAL ), with variation of concentration: 0 % ( control ) , 2.5 % , 5 % , 10 % , 20 % and four of repeated. The results on mortality of imago B. carambolae showed that the concentration of 20 % had significant differences with other concentrations, the percentage of mortality at a concentration of 20 % has a higher rate compared with other concentrations. Percentage mortality of B. carambolae for 72 hours after treatment reached 72 % at a concentration of 20 %. Essential oil of Basil is known have potential as a repellent concerning perch capacity of B. carambolae . The Highest percentage of repellent at each concentration of essential oil ( 2.5 , 5 , 10 and 20 % ) occurred ain the first hour of observation, the percentage of repellent is: 68 , 78 , 78 , and 84 %. Count of larval infestation B. carambolae that appears has a value inversely to the percentage of mortality, and percentage of repellent, the higher the percentage mortality and percentage repellent count of appear larvae is lower . Average count of larvae inclined to decrease in the higher concentration of essential oils . %K Key words : essential oils, B. carambolae , mortality, repellent. %D 2014 %I UIN SUNAN KALIJAGA %L digilib11011
