This work provides the results of a survey of entomonematodes parasites of grasshoppers in grasslands of the Pampean Region, Argentina. Nymphs of Staurorhectus longicornis Giglio-Tos, Laplatacris dispar Rhen, 1939, Dichroplus elongatus Giglio-Tos, 1894 and Metaleptea brevicornis (L.) (Orthoptera: Acrididae) were collected. Mermithidae was the only family registered with seven species: Agamermis decaudata Cobb, Steiner and Christie, 1923, Amphimermis bonaerensis Miralles and Camino, 1983, Amphimermis dichroplusi Camino and Lange, 1997, Amphimermis ronderosi Camino and Lange, 1997, Hexamermis coclhearius Stock and Camino, 1992, Hexamermis ovistriata Stock and Camino, 1992, and Longimermis acridophila Camino and Stock, 1989. The values of parasitism ranged between 1-12%, and intensity not overcome the number of 5.0 nematodes per larva. The nematodes observed showed specificity, not registering the same species of parasite in more than one host species. The Pampean region constituted an area with high diversity of mermithids where new species could be consider as bioregulator agents of this troublesome insect pests in agricultural areas of Argentina.
本文给出了对阿根廷潘帕斯地区草原上蝗虫体内昆虫线虫寄生虫的调查结果。采集了长角星蝗（Staurorhectus longicornis Giglio-Tos）、异色拉普拉蝗（Laplatacris dispar Rhen, 1939）、长翅异距蝗（Dichroplus elongatus Giglio-Tos, 1894）和短角异爪蝗（Metaleptea brevicornis (L.)）（直翅目：蝗科）的若虫。索线虫科是唯一被记录的科，包含7个物种：去尾索线虫（Agamermis decaudata Cobb, Steiner and Christie, 1923）、布宜诺斯艾利斯索线虫（Amphimermis bonaerensis Miralles and Camino, 1983）、异距蝗索线虫（Amphimermis dichroplusi Camino and Lange, 1997）、朗德罗斯索线虫（Amphimermis ronderosi Camino and Lange, 1997）、科氏六索线虫（Hexamermis coclhearius Stock and Camino, 1992）、纹卵六索线虫（Hexamermis ovistriata Stock and Camino, 1992）以及嗜蝗长索线虫（Longimermis acridophila Camino and Stock, 1989）。寄生率在1%至12%之间，感染强度未超过每只幼虫5条线虫。观察到的线虫具有特异性, 没有在一种以上宿主物种中发现相同的寄生虫物种。潘帕斯地区是索线虫种类高度多样的区域，新物种可被视为阿根廷农业区这类害虫的生物调节因子
