The isopod, Armadillidium vulgare (Latreille) (Isopoda: Armadillidiidae), and the millipede, Ommatoiulus moreletii (Lucas) (Diplopoda: Iulidae), are increasingly being reported as pests of emerging broadacre crop seedlings in southern Australia. This is thought to be due to the increased adoption of stubble retention practices, leading to increased abundance of these soil-dwelling organisms. Here, we evaluate the propensity of A. vulgare and O. moreletii to damage a range of crop seedlings. Through the combined analysis of a controlled feeding trial and field reports, we show A. vulgare is able to feed on and damage a range of pulses, legumes, cereals, and oilseeds, as emerging seedlings. O. moreletii had a more restricted range of feeding, being limited to lupin, lucerne, and canola in the feeding trial. These results are discussed in the context of developing pest management guidelines for these species.
潮虫，即普通鼠妇（Armadillidium vulgare (Latreille)，等足目：鼠妇科），以及千足虫，即莫氏马陆（Ommatoiulus moreletii (Lucas)，倍足纲：姬马陆科），越来越多地被报道为澳大利亚南部新兴的大面积作物幼苗的害虫。据认为，这是由于留茬做法的采用增加，导致这些土壤栖息生物的数量增加。在此，我们评估了普通鼠妇和莫氏马陆对一系列作物幼苗造成损害的倾向。通过对一项对照饲养试验和田间报告的综合分析，我们表明普通鼠妇能够以一系列豆类、豆科植物、谷物和油籽的幼苗为食并造成损害。在饲养试验中，莫氏马陆的取食范围较窄，仅限于羽扇豆、苜蓿和油菜。本文在为这些物种制定害虫管理指南的背景下讨论了这些结果。
