Abstract

Purpose

The brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae), is an invasive and a highly polyphagous species with a strong dispersal capacity. Unfortunately, there is currently no effective control method that can prevent or reduce the economic loss caused by this pest. Among natural enemies, microsporidia cause infections in insects so that they can generally shorten life span, reduce fertility and inhibit growth.

Methods

Current study involved field study, light and electron microscopy and molecular phylogenic analyses of a microsporidian pathogen in the populations of H. halys in Türkiye.

Results

The microsporidian infection were mostly observed in malpighian tubules and fatty tissue filled with high spore density. Fresh uninucleate spores are oval, measued as 3.73 × 2.01 µm in dimensions. The mature spore wall is relatively thick and measures 75–85 nm and consists of a clear endospore (40–50 nm) and an electron-dense, uniform, thin exospore (25–30 nm). The polar filament is isofilar, 85–110 mm in diameter and has 7–8 coils. It is found to be most closely related to Nosema maddoxi isolate Mn.6 isolated from H. halys in Georgia in phylogenetic tree.

Conclusion

The spore morphology and structural features of the isolate from H. halys identify it as Nosema maddoxi. The phylogenetic analyses confirm both light and electron microscopic observations. This is the first microsporidian record from H. halys and also from the order Hemiptera in Türkiye. It is also confirmed that the invasive pest, H. halys carries its natural pathogen, N. maddoxi to new geographical locations during its distribution.

中国褐纹蝽Halyomorpha Halys(半翅目:蝽科)种群中微孢子虫病原微孢子虫Nosema Maddoxi的首次记录和鉴定。
目的:褐纹臭虫(半翅目:蝽科)是一种高度多食性的入侵物种,具有很强的传播能力。不幸的是,目前没有有效的控制方法可以预防或减少这种害虫造成的经济损失。在天敌中,微孢子虫引起昆虫感染,一般会缩短昆虫寿命,降低生育力,抑制生长。方法:目前的研究包括野外调查、光镜、电镜和分子系统发育分析等。结果:微孢子虫感染多见于孢子密度较高的马尔比氏小管和脂肪组织。新鲜的无核孢子呈椭圆形,尺寸为3.73 × 2.01µm。成熟孢子壁相对较厚,长度为75-85 nm,由一个透明的内孢子(40-50 nm)和一个电子密集、均匀、薄的外孢子(25-30 nm)组成。极性长丝是等丝,直径85-110毫米,有7-8个线圈。在系统发育树上,发现它与从乔治亚州的H. halys中分离的Nosema maddoxi分离株Mn.6亲缘关系最密切。结论:该分离株的孢子形态和结构特征鉴定为麦地小孢子虫。系统发育分析证实了光镜和电镜观察结果。这是在海蝇中发现的第一个微孢子虫记录,也是在台湾地区发现的第一个半翅目微孢子虫记录。此外,还证实了入侵害虫halys在其分布过程中携带其天然病原体maddoxi到新的地理位置。

期刊介绍: Acta Parasitologica is an international journal covering the latest advances in the subject. Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews. The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
