The entomogenous nematodes Steinerema feltiae and S. bibionis did not penetrate the roots of corn, Zea mays, to infect larval northern corn rootworm (NCR), Diabrotica barberi, feeding within. Laboratory bioassays against first instar NCR indicated that S. feltiae, Mexican strain (LD = 49 nematodes/insect) is more virulent than S. bibionis (LD = 100). Numbers of NCR larvae in a grain corn crop were reduced by both nematode species applied at corn seeding time at the rate of 10,000 infective-stage juveniles per linear meter of corn row. The chemical insecticide fonofos provided significantly better control than either nematode species.
昆虫病原线虫斯氏线虫属的费氏斯氏线虫和比氏斯氏线虫不会穿透玉米（Zea mays）的根部去感染在根内取食的北方玉米根虫（NCR，Diabrotica barberi）幼虫。针对一龄期北方玉米根虫的实验室生物测定表明，墨西哥品系的费氏斯氏线虫（致死剂量=49条线虫/昆虫）比比氏斯氏线虫（致死剂量=100条线虫/昆虫）毒性更强。在谷物玉米作物中，于玉米播种时以每线性米玉米行10000条感染期幼虫的速率施用这两种线虫，均可减少北方玉米根虫幼虫的数量。化学杀虫剂地虫硫磷提供的防治效果明显优于这两种线虫中的任何一种。
