The present investigation shows inoculation of Beauveria bassiana causes change in Total haemocyte count (THC) and Differential haemocyte count (DHC). Subsequent treatment of plant extract Curcuma longa, Aegemone mexicana and Clerodendrum multiflorum showed the antifungal effect and maintain the normal physiological condition of B. bassiana treated larvae. After the treatment of plant extract the physiological condition is more or less similar to the control of both PM and CSR2 race of Bombyx mori L. The 25.78% and 22.09% THC was increased in B. bassiana inoculated larvae of both PM and CSR2 respectively.
