The results revealed that thiamethoxam-25 WG @ 25g a.i/ha (1.00) was recorded with maximum jassid mortality, while lambda cyhalothrin-5 EC @ 25ml a.i/ha (3.42) showed maximum mean population count i.e. lowest mortality up to seven days after application. The second spray 10 days after first application also showed similar results as follows; thiamethoxam-25 WG @ 25g a.i/ha (0.87) maximum jassid mortality while triazophos-40 EC @ 750ml a.i/ha (3.13) showed minimum mortality up to 7 days after application. The effectiveness of these treatments was reflected in terms of reduction in population of jassid and green fruit yield. The results were reflected in terms of % increase over control are as follows; thiamethoxam 25 WG @ 25g a.i/ha plot gave maximum increased fruit yield 66.3% while lambda cyhalothrin-5 EC @ 25ml ai/ha showed 26.1% with minimum increase in fruit yield.
