Pest is one of limiting factor-pursuing improvement of agriculture crop product. Caterpillar (Plutella xylostella) be pest damaging produce of crop especially vegetables like cabbage, broccoli, cabbage flower, mustard, petai, cress, radish. Prevention applies synthetic pesticide simply still generating problem like existence of negative impact good for mortal and for area. Now is being strived applies vegetation pesticide Exploiting of crops as vegetation insecticide active agent producer is one of alternative of capable to lessen damage to area of for example value leaf (Pogostemon cablin). Sapphire leaf (Pogostemon cablin) be one of plant containing neglect compound pinen which is functioning as insecticide and have the character of biodegradable so that safe for area, hence done research to see existence of giving influence of value leaf filtrate (Pogostemon cablin) to caterpillar larva mortality (Plutella xylostella). Purpose of this research is to know giving influence of value leaf filtrate (Pogostemon cablin) to caterpillar larva mortality (Plutella xylostella). To know at concentration of how much/many value leaf filtrate (Pogostemon cablin) that most effective to caterpillar larva mortality (Plutella xylostella). Research method applies completely randomized design (RAL) with seven treatments that is 0%, 50%, 60%, 70%, 80%, 90%, 100% and 4 restating. Place and research time is executive in chemical laboratory on 27 October to 29 October 2008. Population at this research is caterpillar (Plutella xylostella) instar three breaded in Balai Penelitian Tanaman Tembakau and Serat in Malang. Number of samples 280 tails, data analysis applies one way anava and continuation test with Duncan's test 5%. Result of analysis anava indicates that Fhitung > Ftabel at level significant (0,05) is meaning shows there are difference of real influence of giving of value leaf filtrate (Pogostemon cablin) to caterpillar larva mortality (Plutella xylostella). At concentration of 80% and 90% value leaf filtrate (Pogostemon cablin) can give the same effectively with highest concentration that is 100% so that concentration of 80% has applicable to kill caterpillar (Plutella xylostella).
