ABSTRACT

Both Ageratum conyzoides and Ageratum vulgaris have been used to manage pest throughout the world. Spodoptera litura (Fab.) (Lepidoptera: Noctuidae) is one of the pests of field crops and has been developed resistance against most of the modern classes of synthetic pesticides worldwide. S. litura third and fifth instar larvae treated topically with 0.1µg of A. conyzoides and A. vulgaris were found to be significantly reduce total head protein after 24, 48 and 72 hours of treatment application over control. Similar trend was also observed when these plant extracts injected at 0.01 µl/ insect. Furthermore both A. conyzoides and A. vulgaris have similar impact on S. litura third and fourth instar larvae. These two plants can be used as botanical insecticide in pest management programme.
