Effects on the recently introduced dung-burying beetle, Onthophagus gazella F, on free-living stages of equine strongyles were determined on a Texas pasture. Two populations of O gazella (22 and 44 pairs) were exposed to 1-kg deposits of equine dung containing 545,000 strongyle eggs for 31 days near the end of the beetle's activity season. Weekly dung and pasture samples were taken from these plots and from control plots from which beetles were excluded to recover developing larvae. Significant differences did not occur among the 3 treatments (P less than 0.05).
在得克萨斯州的一片牧场上，研究了新引入的粪埋甲虫（Onthophagus gazella F）对马圆线虫自由生活阶段的影响。在甲虫活动季节接近尾声时，将两组粪埋甲虫（分别为22对和44对）暴露于含有545,000个圆线虫卵的1千克马粪堆中31天。每周从这些试验区以及排除了甲虫的对照试验区采集粪便和牧场样本，以回收发育中的幼虫。三种处理之间未出现显著差异（P小于0.05）。
