In the present investigation on total of 4 different media PDA, SDAY, CMA, MEA were evaluated for their biological attributes and levels of virulence against the target pest, Paracoccus marginatus. Among test media SDAY showed maximum radial growth (67.39 mm), highest conidial concentration (1.75x109), highest percentage of conidial viability (98.68 per cent) and highest virulence against mealy bug (94.00 per cent). PDA found to be the next promising isolate with radial growth of 60.33 mm, conidial concentration of 1.57x109, conidial viability of 94.77 per cent and virulence of 90.00 per cent. Least radial growth (44.53 mm), conidial concentration (1.07x109), conidial viability (83.28 per cent) and virulence (76.00 per cent) were noticed in SDAY media. The findings of the present investigation also gave information pertaining to the strain development among different media in terms of the above mentioned biological attributes. On the basis of the data obtained and also in the view of above inferences SDAY media recorded good results.
