Abstract

The brown marmorated stink bug (Halyomorpha halys), a native of Asia, has become an invasive pest in North America and Europe. Given the severity of H. halys and the need for better and environmentally-friendly control methods for this pest, we evaluated the virulence four entomopathogenic nematode species (Heterorhabditis indica, Oscheius myriophilus, Steinernema eapokense and Steinernema pakistanense) that occur naturally in soils in southern Việt Nam and compared them with that of a commercially available strain of S. carpocapsae. We report for the first time the pathogenicity of Oscheius myriophilus towards BMSB. The commercial strain of S. carpocapsae was most virulent against BMSB. However, the strain of S. pakistanense isolated from soil in southern Việt Nam has potential for the biological control of this pest. To achieve this potential, further work is needed including evaluation in the field and with the formulation of the nematode inoculum.

在实验室条件下Việt Nam昆虫病原线虫对褐纹臭虫的防治效果。

原产于亚洲的褐纹臭虫（Halyomorpha halys）已成为北美和欧洲的一种入侵害虫。鉴于halys的严重程度和对这种害虫的更好和环保的控制方法的需要，我们评估了四种昆虫病原线虫（Heterorhabditis indica, Oscheius myriophilus， Steinernema eapokense和steinerma巴基斯坦）在Việt南土壤中自然存在的毒力，并将它们与市售的S. carpocapsae菌株进行了比较。我们首次报道了嗜肉芽奥舍伊菌对BMSB的致病性。商品菌株对BMSB的毒力最强。然而，从Việt Nam南部土壤中分离的S. pakistani菌株具有生物防治该害虫的潜力。为了实现这一潜力，需要进一步的工作，包括实地评价和线虫接种物的制定。

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.
