Increasing densities of Steinernema glaseri infective juveniles (IJs) in soil affected penetration efficiency and reproduction of the nematodes in larvae of the greater wax moth Galleria mellonella. The penetration efficiency and the proportion of penetrated IJs developing to adults decreased significantly with increasing numbers of IJs present in the soil and entering the hosts, respectively. The number of progeny produced/host cadaver initially increased, with the highest production being between 20.7 +/- 3.3 and 58.0 +/- 6.6 IJs established/host +/- SE and decreased at higher densities. Above 184.4 +/- 37.7 IJs established/host, no progeny emerged from the cadavers.
土壤中格氏斯氏线虫感染性幼虫（IJs）密度的增加影响了线虫对大蜡螟幼虫的穿透效率及繁殖。随着土壤中存在并进入宿主的IJs数量增加，穿透效率以及穿透后发育为成虫的IJs比例分别显著下降。每个宿主尸体产生的后代数量最初增加，在每宿主建立20.7±3.3至58.0±6.6条IJs时产量最高，而在更高密度时下降。每宿主建立超过184.4±37.7条IJs时，尸体中未出现后代。
