A total of 282 short-horned grasshoppers (Acrididae) was collected in a mountainous area of New Zealand's South Island and examined for hairworm (Nematomorpha) infections. Thirteen percent of female Sigaus obelisci and 3% of female S. australis harbored hairworms; males of both species, as well as male and female S. campestris, were all uninfected. All hairworms recovered belong to the species Euchordodes nigromaculatus, previously known only from wetas (Orthoptera: Stenopelmatidae). No size differences were observed between infected and uninfected grasshoppers, and there was no relationship between host size and worm length. This is the first substantiated report of nematomorphs in grasshoppers in New Zealand.
在新西兰南岛的一个山区共采集了282只短角蝗虫（蝗科），并对其进行了铁线虫（线形动物门）感染检查。13%的雌性奥氏西格蝗和3%的雌性南方西格蝗体内有线虫寄生；这两个物种的雄性以及原野西格蝗的雄性和雌性均未被感染。所有回收的线虫均属于黑斑尤线虫，此前仅在沙螽（直翅目：沙螽科）中发现过。未观察到受感染和未受感染蝗虫之间的大小差异，宿主大小与线虫长度之间也没有关系。这是新西兰蝗虫体内存在线虫的第一份确凿报告。
