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.

Key words: Spodoptera litura, Leaf-disc treatments, Larvae, Leaf extracts.
