Description :
During three consecutive year from 2009-2012 the analysis of pathogenic mortality at larval stages caused significantly high (16.90 – 39.08 %). Among the pathogenic mortality viral pathogens were prominent and causing high mortality (5.14 – 29. 52 %) than the bacterial pathogen (02.00 – 23.97 %). The highest predaceous mortality was recorded during cycle II in the year 2009-10 it was 45.38% and lowest mortality 02.06% was recorded during cycle I in the year 2011-12. Among the predaceous mortality, the vertebrate pest infestation is higher during II cycle in the year 2010-11 and it was 29.00 %. The infestation of wasp was zero during cycle I in each year but highest infestation was recorded during cycle II in the year 2009-10 followed by pest sting bug (06.56 %) during same year. This study indicates that, the pathogenic and the predaceous mortality was more prominent in Bondgaon/Devi field of Gondia district of Vidarbha, Maharashtra.
