Indeks Pertumbuhan Larva Aedes Aegypti L. Yang Terdedah Dalam Ekstrak Air Kulit Jengkol (Pithecellobium Lobatum)

S. The control of dengue fever (DBD) vector generally use the synthetic insecti­cides, however it's utilization had negative effect to the environment. Jengkol (Pithecellobium lobaturn) was one of the plants which could be used as larvacide alternative because it had phenolate acid, alkaloid, terpenoid and saponin in its rind. This research was conducted to know the growth index of Aedes aegypti larvae which was soaked in the extract ofP. lobaturn rind. This experiment used P. lobaturn rind ekstract at concentration 36%, 18%, 9% and 0% . The data were analyzed by using Zhang et.al methode (1993). The P. lobaturn rind extract were toxic to larvae especially in first and second instar at concentration 17,94% respectively. Relativelly growth index range from 0,817-1, it is mean that some larvae were stuned, and some were growth into the next phase
