Effectiveness of n-hexane and ethanol extract of papaya (Carica papaya L.) leaves as shallot pest (Spodoptera exigua Hübner) natural insecticide

One of the agricultural commodities that has a high selling value and consumption level is shallot (Alium ascalonicum). However, productivity shallots known to be susceptible plant-destroying organisms, such as caterpillar (Spodoptera exigua). Currently, most farmers control S. exigua using synthetic insecticides. Synthetic insecticides are poisonous use for long time period will cause resistance pests environmental pollution. natural ingredients potential botanical insecticide papaya (Carica papaya). This study aimed determine effectiveness concentration n-hexane ethanolic extracts leaves which effective against toxicity inhibition feeding power second instar larvae. The extract was obtained by gradual maceration (non polar) ethanol (polar) solvents. Test secondary metabolite content Thin Layer Chromatography (TLC). results showed in causing larvae with highest percentage 96.67%. Meanwhile, more inhibiting larval than lowest area 2,27 mm. 3%. LC50 0.0207% 0.0459%. Both contain compound groups, namely tannins, terpenoids, flavonoids, alkaloids.
