From the results of a number of studies it is concluded that: (1) Cattle of a large proportion (approximately 80 per cent) of the dairy farms in the Netherlands were infected with L3 larvae of Dictyocaulus viviparus during the grazing season in 1981. (2) Experiments showed a significant negative cubic effect on the level of infection with L3 larvae of D. viviparus on the growth of calves. (3) Sporangia of Pilobolus kleinii harbouring L3 larvae were shot significantly further away than sporangia not harbouring L3 larvae.
（1）1981年放牧季节期间，荷兰相当大比例（约80%）的奶牛场的牛感染了胎生网尾线虫的L3幼虫。（2）实验表明，胎生网尾线虫L3幼虫的感染水平对犊牛生长有显著的负三次方效应。（3）携带L3幼虫的kleinii卷头霉的孢子囊比不携带L3幼虫的孢子囊弹射得更远。
