The six promising isolates of B. bassiana (NBAII-Bb-5a, 7, 14, 19, 23 and 45) were examined for Environmental Scanning Electron Microscopy studies (ESEM) and two B. bassiana isolates (NBAII Bb-5a and Bb-45) were used for Transmission Electron Microscopy (TEM) studies for their endophytic colonization in maize leaf tissues. All the six isolates showed the conidial germination and penetration after 5 days of treatment in maize leaf tissues through Environmental Scanning Electron Microscopy (ESEM) studies. Conidia of Bb-5a and Bb-45 isolates were observed inside the parenchymatic cells through Transmission Electron Microscopy (TEM) studies. This indicates the endophytic establishment of B. bassiana in maize leaf tissues.
