Abstract:
Pulse beetle (Callosobruchus chinensis) is most serious pest of stored grains. It affects variety of food grains by causing deterioration and loss in quality. This study aimed to evaluate the repellent activity of three botanicals sweet flag (Acorus calamus), black pepper (Piper nigrum) and clove (Syzygium aromaticum) against adult of store grain pests pulse beetle with three replications in Completely Randomized Design (CRD) through filter paper assay. Repellency was recorded after 12 h, 24 h, 48 h and 72 h of post-treatment. The result revealed that rhizome extract of sweet flag shows significantly maximum repellency 90.07% than black pepper 83.51% and clove 80.13%. Utilization of sweet flag extract for its potential repellent effect can be effectively used for controlling store grain pests.
