ABSTRACT
Nine botanical plant powders like neem, tulasi, notchi, adhathoda, bitter gourd, black pepper, turmeric, ginger and sweet flag were treated against pulse beetle, C. chinensis on chickpea seeds. After 24, 48 and 72 HAR of C. chinensis, the botanical powders like turmeric and ginger exhibited to be the maximum numbers of adults were oriented in chickpea (13.00 & 15.33, 12.00 & 13.66, 9.66 & 11.00). Whereas, minimum number of adults oriented was recorded in sweetflag (3.33, 2.33 & 1.00). At the same time, longevity period was short or minimum days were also observed in sweetflag treated seeds; whereas in male it was 1.66 and in female was 2.33 followed by notchi and in neem. While in control the longevity period of male and female was 8.00 and 9.66 days. At 48 hours after release the data revealed that sweetflag shows better result in controlling C. chinensis with per cent mortality (26.00%) followed by notchi (25.00%) and neem (24.00%). The number of eggs laid on chickpea seeds was found to be less in sweetflag seeds at different DAT (21.33, 30.00 and 41.66 no's respectively).
