Many grasses in the subfamily Pooideae form symbioses with Neotyphodium fungal endophytes. This relationship provides a competitive advantage for the host plant in many ways. The endophyte of meadow fescue ( Festuca pratensis), Neotyphodium uncinatum, is considered to produce no mammalian toxins, but produces metabolites giving insect resistance and other ecological benefits. To determine the potential of N. uncinatum strains to reduce the development of rice leaf bug ( Trigonotylus caelestialium), we investigated the effect of artificial inoculation of Italian ryegrass ( Lolium multiflorum) with N. uncinatum on the feeding of T. caelestialium. T. caelestialium larvae significantly preferred endophyte-free to endophyte-infected plants. Survival of insects was very high on endophyte-free plants, but it rapidly declined on infected plants. These results indicate that N. uncinatum-infected Italian ryegrass has enough resistance to T. caelestialium and it means the control of T. caelestialium may be possible using this endophyte.
