Abstract

ABSTRACT Dragon scale fern (Pyrrosia piloselloides (L.) M. G. Price) is one of the plants that grows and spreads wild throughout the tropics and this plant is an epiphyte (a plant that attaches to the stems of other plants), but is not a parasite because this plant can make its own food. This study aims to test the larvicidal and oviposition deterrent activities of the methanol extract of dragon scale fern. Dry leaves of P. piloselloides (L.) M. G. Price were macerated with methanol to produce 30.5 g of methanol extract. Methanol extract contained secondary metabolites compounds of steroid, saponin, flavonoid, and tannin. The methanol extract was tested for larvicidal and oviposition deterrent activities against Culex sp. mosquitoes with concentrations of 31.25; 62.50; 125; 250; 500; 1000; and 2000 ppm. The results showed strong larvicidal activity (toxic) with an LC50 value of 143 ppm, and oviposition deterrent activity produces % ER of 72% at a concentration of 2000 ppm. The results of the study showed that methanol extract of dragon scale fern can be used as a natural larvicidal and oviposition deterrent, this activity is contributed by the presence of secondary metabolite compounds, especially flavonoids, saponins, tannins, and steroids.
