Control Of Cotton Pest (Mylabris Cichorii) Using Azadirachta Indica Leaf And Stem Bark Extracts

Abstract

 The present study was investigated important medicinal plant extract A. indica stem bark aqueous extract against the fourth instars larvae of cotton Pest, During the experimental period insects’ weight were significantly decreased from 24, 48, 72 and 96 hrs of exposure time of leaves and stem bark aqueous extract of A. indica treated against M. cichorii.    The high percent mortality presents in the 800-ppm concentration of T. arjuna at 96 hrs exposure time of leaves extract followed by 600, 400, and 200 ppm, respectively. The high percentage mortality was observed in the 800-ppm concentration of A. indica at 96 hrs exposure time of leaves extract followed by 600, 400, and 200 ppm, respectively. The high percentage mortality was observed in the 400-ppm concentration of A. indica at 96 hrs exposure time of stem bark extracts followed by 800, 600, and 200 ppm, respectivel. These results have been suggested that the A. indica plant leaves and stem bark aqueous extracts were used as the integral pest management studies of the cotton pest, M. cichorii.
