Abstract

Vespa orientalis is spreading across the Italian and European territories leading to new interactions among species, which could lead to the transmission of pathogens between species. Detection of honey bee viruses in V. orientalis has already been revealed in both adults and larvae, while no information is available regarding parasitic occurrence. Sixty adult hornets collected across apiaries in the South of Italy were subjected to cytological, histopathological and biomolecular examination to evaluate the occurrence of Nosema ceranae, Ascosphaera apis, Lotmaria passim, Crithidia mellificae, and Crithidia bombi.

Cytological examination revealed the presence of Nosema spores in 38.33% of individuals while histopathological analysis showed the presence of L. passim-like elements in the rectum of two examined specimens and the presence of fungal hyphae in the small intestine of another hornet. Biomolecular investigation revealed that N. ceranae was the most prevalent pathogen (50.0%), followed by A. apis (6.66%), L. passim (6.66%) and C. bombi (6.0%).

1771 年东方灶神 Vespa in Orientalalis linneus 中 Nosema ceranae、Ascosphaera apis 和 trypanosomatids 的出现。

东方蜂（Vespa orientalis）正在意大利和欧洲领土上蔓延，导致物种之间产生新的相互作用，这可能导致病原体在物种之间传播。已经在东方大黄蜂的成虫和幼虫体内发现了蜜蜂病毒，但还没有关于寄生虫发生的信息。对在意大利南部各养蜂场收集的 60 只成年大黄蜂进行了细胞学、组织病理学和生物分子检查，以评估 Nosema ceranae、Ascosphaera apis、Lotmaria passim、Crithidia mellificae 和 Crithidia bombi 的发生情况。细胞学检查显示，38.33%的个体体内存在诺斯马孢子，而组织病理学分析表明，两只受检样本的直肠中存在类L. passim元件，另一只大黄蜂的小肠中存在真菌菌丝。生物分子调查显示，N. ceranae 是最常见的病原体（50.0%），其次是 A. apis（6.66%）、L. passim（6.66%）和 C. bombi（6.0%）。

期刊介绍： The Journal of Invertebrate Pathology presents original research articles and notes on the induction and pathogenesis of diseases of invertebrates, including the suppression of diseases in beneficial species, and the use of diseases in controlling undesirable species. In addition, the journal publishes the results of physiological, morphological, genetic, immunological and ecological studies as related to the etiologic agents of diseases of invertebrates. The Journal of Invertebrate Pathology is the adopted journal of the Society for Invertebrate Pathology, and is available to SIP members at a special reduced price.
