Two hundred and thirty nine sesame germplasm lines were screened to develop methodology and to identify resistance to the sesame pod bug, Elasmolomus sordidus under natural field condition during 1995 (Trial I) and a trial of 81 entries including seven resistant cultures of first trial, eight pre release cultures and 34 advanced breeding materials...

The comparative performance of sesame pod bug Elasmolomus sordidus on four different host seeds viz. sesame, groundnut, sorghum and bajra was studied under laboratory condition in terms of egg hatchability, nymphal duration, nymphal mortality, oviposition period, fecundity and adult longevity. The egg hatchability was higher on groundnut (54.6%) an...

Six plant products namely, neem oil (20%), neem seed kernal extract NSKE (5%), leaf extracts of Prosopis juliflora (5%), Ipomoca carnea (5%), Vitex negundo (5%) and Azadirachta indica (5%) were evaluated with a standard insecticide, carbaryl 10 D for their efficacy against sesame pod bug (SPB) incidence, pod damage and yield during Summer '96 and K...
