Inhibitory effect of endophyte on feeding insects is mostly due to toxin produced by fungal endophyte. Endophytic fungi alone or in association with host plant are able to produce toxin (Petrini 1992; Sumarah and Miller 2009). Highly diverse groups of toxin produced by fungal endophyte i.e. alkaloids, terpenoid, steroid, quinone, and flavonoid, phenylpropanoids and lignans, peptides, phenol, phenolic acids and aliphatic compounds (Tan and Zou 2001). Siegel et al. (1990) stated that toxin produced in grasses infected by endophyte Acremonium coenophialum and Epichloe typina is peramine, lolitrem B and ergovaline. Moreover reported that endophytic fungus Phyllosticta sp. and Hormonema dematioides in balsam fir produce toxic
