Brown cockroaches, Periplaneta brunnea Burmeister, were exposed to increasing population densities of the entomogenous nematode, Steinernema carpocapsae (Weiser), All Strains. A total of 160 adult cockroaches were used, 40 for each of four treatments: 0, 3,000, 30,000, and 300,000 infective juveniles added to 50 cm3 of sand. Population densities of 30,000 and 300,000 infective juveniles per 50 cm3 sand were the most effective treatments, killing 55% of the P. brunnea. The highest population density of nematodes, 300,000 infective juveniles per 50 cm3 sand, killed 93% of the P. brunnea, and produced a more rapid mortality when compared with other population densities.
将棕色蟑螂（Periplaneta brunnea Burmeister）暴露于昆虫病原线虫斯氏线虫（Steinernema carpocapsae (Weiser)，所有品系）不断增加的种群密度环境中。总共使用了160只成年蟑螂，分为四种处理方式，每种处理40只：分别向50立方厘米的沙子中添加0、3000、30000和300000条感染性幼虫。每50立方厘米沙子中添加30000和300000条感染性幼虫的种群密度处理效果最佳，杀死了55%的棕色蟑螂。线虫最高种群密度，即每50立方厘米沙子中300000条感染性幼虫，杀死了93%的棕色蟑螂，与其他种群密度相比，死亡率上升更快。
