In the present study, lichen(Parmelia sp.) extract showed insecticidal activity against Aedes albopictus, and the effect of growth inhibiting activity was investigated. Acetone and methanol extracts of the lichen against larvae of Aedes albopictus were showed high insecticidal activities in low lethal concentration. 50% lethal concentration of the acetone extractof the lichen is 0.13% and the 50% lethal concentration of methanol extract of lichen is 0.15% respectively. This experiment that used acetone and methanol extracts of the lichen were observed for 24, 48 and 72 hours. As a result, the higher concentration and the longer exposure time is increased mortality against Aedes albopictus. Pupation time took more time as the higher concentration of acetone extract of lichen. Consequently, the lichen extract is effect in inhibiting the growth of Aedes albopictus larvae. In this experiment indicates that lichen extract has activity against Aedes albopictus and is available as the natural insecticide.
