Abstract

A number of insects are deterred from feeding on grasses by alkaloids produced in planta by Neotyphodium endophytes (Popay and Rowan, 1994). Also, alkaloids associated with endophyte-infected grasses are toxic to some herbivorous insects. The objectives of this study were to determine the ability of fall armyworm to discriminate between tall fescue (TF), meadow fescue (MF) and perennial ryegrass (PRG) infected with various Neotyphodium endophytes and their endophyte-free counterparts.
