Abstract

Coffee is an important commodity in Indonesia, its production continues to decrease from year to year. One of important pest is the mealybug (Planococcus citri), the production lost due to a severe attack can reach 90%. Farmers still using synthetic insecticides to control the pest, which have negative effect on the environment and humans buying. To reduce its, necessary to find the environment friendly insecticides (botanical insecticide). One of the plant can be used as botanical insecticide is Gliricidia maculata. The purpose of the study to obtain flavonoid compound from polar extract (water and methanol) of G. maculata leaves, as botanical insecticide throught out isolation and purification. To compare the effective concentration of the flavonoid compounds from polar extract (water and methanol) of powder leaveas G. maculata on mortality coffee mealybug. A set of laboratory experiment was conducted by using block design. Water and methanol extracs (WE and ME) with 5 levels concentration i.e. 0%, 0.01%, 0.02%, 0.03% and 0.04%, and 3 replications. Mealybug mortality observed at 12, 24, 48, 72 hours after treatment. Analisys Probit were used for Determine LC50 values, ANOVA and Tukey’s test was used to determine an effective formula botanical insecticide. The results showed that the polar extract (water and methanol) Gliricidia leaves contains flavonoids that act as insecticides against coffee mealybug (P.citri) with LC50 72 hours water extract 0,033% and metanol extract 0,039%. Keywords: Botanical insecticide flavonoids, powder leaves (Gliricidia maculata), coffee mealybug (Planococcus citri).
