Endophytes to which several roles of plant defense are ascribed have huge potential for development as biocontrol agents. Biocontrol prospects of two foliar endophytes, Phlebiopsis gigantea and Phanerochaete sordida isolated from Adhatoda vasica Nees and Andrographis paniculata Nees, respectively, are reported here. In per os treatment against third instar teak defoliator larvae [Hyblaea puera (Cramer)], P. sordida and P. gigantea showed considerable insecticidal activity in terms of median lethal doses (6x105 conidia and 3x108 oidia per larva, respectively). In dip treatment using oidial suspension, P. gigantea at its median lethal dosage inflicted cent percent mortality in less than a minute's time. This result is extremely fascinating considering its knockdown action and its enormous potential as a biocontrol agent.
