Abstract/Contents:"Although it was known for many years that ryegrass ecotypes in New Zealand were typically infected with an endophyte it was not until 1981 that pasture researchers established a link between endophyte and resistance to certain insects. Since then much of our knowledge about insect resistance of endophyte infected perennial ryegrass comes from the pasture industry with only limited research in the turf industry. New Zealand has many significant insect pests of ryegrass, including Argentine stem weevil, black beetle, and pasture mealy bug which have been shown to be affected by the "endemic" endophyte of turf ryegrass which produces the alkaloids peramine, lolitrem and ergovaline. Turf ryegrass cultivars infected with "endemic" endophyte are widely used within the New Zealand turf industry. Cultivars with endophyte have greater turf density and persistence throughout much of New Zealand and indeed in some regions in some years cultivars lacking endophyte may not persist beyond one summer. Turf ryegrass cultivars bred in New Zealand are endophyte infected and breeders usually maintain their seed stock under cool dry conditions to ensure endophyte infection is maintained. The seed industry in New Zealand generally tries to supply turf ryegrass cultivars with endophyte and takes care to monitor viable endophyte levels in both seed stocks and harvested seed to ensure endophyte infected cultivars are delivered to the turf industry. Further improvements in insect resistance to other New Zealand pests, porina and root aphid have been shown in an experimental endophyte AR37 that produces janthitrem alkaloids. The use of such endophytes should offer potential to further improve turf performance in the future."
