Abstract

The aim of this research was to determine the behavioral response of Riptortus linearis to the application of organic insecticides (extract of Cerbera manghas leaf). The experimental method refers to Garber (1951). Young long bean pods soaked for 10 seconds in the solution of Bintaro Leaf extract with the concentrations of : K0 = 0.0%, K1 = 2.5%, K2 = 5%, K3 = 7.5%, K4 = 10%, K5 = 12.5%. Long bean pods is hung in a rectangular mosquito net lid and inserted in 3-4 of instar of R. linearis larvae as many as 20 animals per replicate. The number of insect perched on the pods of each treatment is observed every day. The results showed that the number of dead and perched insects did not differ significantly among the treatments. The conclusion was the application of Bintaro Leaf extract didnot give influence to the presence and death of R. linearis. Keywords: R. linearis, Bintaro leaf extract
