During growth inside the host, fungus produces various kinds of toxic secondary metabolites, which are insecticidal.
These secondary metabolites take the insect to its final life stage and ultimately insect dies out. Fungal mycelium emerges out through the cuticle and lead to the formation of fruiting body under suitable environmental conditions (Webster 1980).
Morphological features of fruiting body include stipitate, yellowish-orange to orange to reddish-orange fruiting stroma which is cylindrical to slightly clavate in shape.
Stipes of 1.5- to 3-mm thickness with fertile clava terminal (2.0- to 6.0-mm wide) are also commonly seen in the fruiting body with overall stroma of about 1.5- to 7.0-cm tall which can vary in length depending on the size of the host.
