ABSTRACT
In the present study the pesticidal effect of leaf extracts of Catharanthus roseus has been evaluated
against the larvae of Spodoptera litura. Result show that in 3rd Instar Larvae, Larval mortality was
82.69 and 78.60 percent when larvae were treated at 2.5 % extract by topical and leaf-disc
treatments respectively. In 5th Instar Larvae, Maximum mortality of 81.67 and 62.66 percent was
observed at 2.5% extract. In 6th Instar Larvae, 78.66 and 57.33 percent mortality was recorded when
larvae were treated by 2.5% extract. From the results, it is evident that the plant tested possessed
significant larvicidal properties and caused high mortality in larvae of Spodoptera litura.
Keywords: Spodoptera litura, Leaf-disc treatments, Larvae, Leaf extracts.
