Despite being recognised as a serious pest of turf grasses in Australia, there has been limited research into the southern sting nematode (Ibipora lolii). This study examined its occurrence and population dynamics in the Perth region of Western Australia and assessed the level of resistance and tolerance of turf grasses to this nematode. In a systematic survey of 90 municipal sports fields on which kikuyu was the most common turf species, I. lolii was detected in 51% of sites. The mean population density was 27 nematodes/200 mL soil, but was almost eight times higher in localised areas where symptoms were severe. Infested turf tended to be relatively sparse and have a shallow root system. In a 2-year population dynamics study on a kikuyu sports field, I. lolii reproduced year-round, but exhibited a seasonal pattern of fluctuation in population density. Numbers increased when conditions were cool and wet during the winter rainfall period, peaking in October, and then declined during the hot and dry irrigation season. Although the population density of I. lolii was always greatest in the upper 10 cm of the soil profile, nematodes were consistently recovered from depths of 50–70 cm, showing that it was capable of deep vertical movement. A field experiment comparing four cultivars of couch and two cultivars of kikuyu showed that none of the cultivars exhibited resistance or tolerance to I. lolii. Nematode numbers increased rapidly in infested plots, regardless of cultivar, while in comparison with non-infested plots, the mean total plant biomass and root dry weight were reduced by 53% and 88%, respectively.

尽管在澳大利亚被认为是一种严重的草坪草害虫，但对南方刺线虫 ( Ibipora lolii ) 的研究却很有限。这项研究检查了西澳大利亚珀斯地区的发生和种群动态，并评估了草坪草对这种线虫的抵抗力和耐受性水平。在对 90 个市政运动场的系统调查中，基库尤是最常见的草皮物种，在 51% 的场地中检测到I. lolii。平均种群密度为 27 条线虫/200 毫升土壤，但在症状严重的局部地区几乎高出八倍。受感染的草皮往往相对稀疏，根系较浅。在 kikuyu 运动场的 2 年人口动态研究中，I. lolii全年重现，但呈现出人口密度的季节性波动模式。在冬季降雨期间凉爽潮湿的条件下，数量会增加，在 10 月达到峰值，然后在炎热干燥的灌溉季节减少。尽管I. lolii的种群密度总是在土壤剖面的上部 10 cm 处最大，但线虫始终从 50-70 cm 的深度恢复，表明它能够进行深度垂直运动。一项比较四个沙发品种和两个 kikuyu 品种的田间试验表明，没有一个品种对I. lolii表现出抗性或耐受性. 无论栽培品种如何，受侵染地块的线虫数量都迅速增加，而与未受侵染地块相比，平均植物总生物量和根干重分别降低了 53% 和 88%。
