Uji Beberapa Konsentrasi Ekstrak Tepung Daun Paitan (Tithonia Diversifolia (Hemsley) A. Gray) Terhadap Mortalitas Larva Oryctes Rhinoceros L. Di Laboratorium

Oil palm is an important plantation of agriculture. Oryctes rhinoceros is a main pest that attack on oil palm from pra nursery to production. Alternative control that can be develoved is using plants as natural insecticidae. Paitan (Tithonia diversifolia) is one of plants that used as natural insecticide. The research aimed at determining consentration of paitan (Tithonia diversifolia (Hemsley) A. Gray) leaf flour extract which effective towards larvae mortality. The research was conducted in plant pest laboratory of Agriculture Faculty of Riau University. The research was by experiment with a completely randomized design with 5 treatment and 4 repeartings. Treatments of some concentration of paitan leaf extract consist of 0 g.l-1 water, 25 g.l-1 water, 50 g.l-1 water, 75 g.l-1 water and 100 g.l-1 water. The research results showed that concentration 100 g. l-1 water paitan leaf extract with mortality 60%, dead time 27 hours after application and time to kill 50 % larvae O.rhinoceros (LT50) 102 hours after application was not effective yet to kill larvae O.rhinoceros because it was not able to kill pest above 80%. Proper concentration to kill 50% population of larvae is 7,6% or 76 g.l-1 water paitan leaf extract. Concentration was able to kill 95% population of larvae is 187,4% or 1874 g.l-1 water paitan leaf extract.
