在世界各地，数百万公顷的多年生黑麦草草坪和牧场感染了内生真菌，黑麦草新霉。利用草地田鼠（Microtus pennsylvanicus）研究了这些受感染的草对野生动物的影响。食用受感染的黑麦草不会影响圈养雌性田鼠的体重增加，但会减少雄性田鼠的体重增加。草甸田鼠的繁殖率和死亡率与饮食无关。在田间试验中，感染黑麦草的田鼠丰度仅略低于未感染黑麦草的田鼠丰度。在受感染的地块，被田鼠啃咬的苹果树比未受感染的地块少，这表明在田鼠造成损害的地方种植受感染的多年生黑麦草可以减少田鼠造成的问题。(C) 2003 Elsevier Science B.V.版权所有
Throughout the world, millions of hectares of perennial ryegrass lawns and pastures are infected with the endophytic fungus, Neotyphodium lolii. The effect these infected grasses may have on wildlife was investigated using meadow voles, Microtus pennsylvanicus. Consumption of infected ryegrass did not affect weight gain of captive female voles but reduced it in males. Reproductive and mortality rates of meadow voles were similar regardless of diet. In field tests, vole abundance in plots of infected ryegrass were only slightly lower than in plots of uninfected ryegrass. In infected plots, fewer apple trees were gnawed by voles than in uninfected plots suggesting that problems caused by voles may be reduced by planting infected perennial ryegrass at sites where they are causing damage.
