摘要

这是一种昆虫病原线虫和一种自由生活的噬菌体线虫混合感染的报告，它们都入侵了mellonella幼虫，显然表现出强烈的种内竞争。通过光镜、电镜、ITS和28S核糖体DNA区测序和系统发育分析，将分离得到的昆虫病原性线虫分为kankabi Heterorhabditis n. sp.和Metarhabditis rainai。M. rainai噬菌体线虫被认为是兼性坏死线虫，因为它消耗昆虫病原线虫获得的食物资源，直接影响后者的生命周期，阻止它们的发育，迫使它们离开G. mellonella寻找新的宿主。

A new entomopathogenic nematode species and its association with a facultative necromenic nematode.

This is the report of mixed infection of an entomopathogenic nematode and a free-living bacteriophage nematode both invading Galleria mellonella larvae, apparently showing strong intraguild competition. The entomopathogenic nematodes isolated in this study were classified as Heterorhabditis kankabi n. sp., and Metarhabditis rainai through light and electronic microscopy, sequencing of ITS and 28S ribosomal DNA regions, and phylogenetic analyses. The bacteriophage nematode M. rainai was recognized as a facultative necromenic nematode, as it consumed the food resources obtained by entomopathogenic nematodes, directly affecting the life cycle of the later by stopping their development and forcing them to leave G. mellonella in search of new hosts.

期刊介绍： Helminthologia (HELMIN), published continuously since 1959, is the only journal in Europe that encompasses the individual and collaborative efforts of scientists working on a different topics of human, veterinary and plant helminthology. The journal responsibility is to enrich the theoretical and practical knowledge in very specific areas and thus contribute to the advancements in human and veterinary medicine and agronomy. Taking the advantage of comprehensive and multidisciplinary approaches journal still maintains its original spirit and is principal source of fresh scientific information regarding helminths, endoparasites and plant parasites. Addressing the most up-to date topics journal gained rightful and exceptional place next to the other high-quality scientific journals publishing in its field.
