The oak lace bug (OLB), Corythucha arcuata (Hemiptera: Tingidae), was first identified as an invasive pest in Europe in northern Italy in 2000 and since then it has spread rapidly, attacking large forested areas in European countries. The OLB is a cell sap-sucking insect that is native to North America, with Quercus spp. as its main host. Its rapid expansion, successful establishment in invaded countries, and observations of more damage to hosts compared to native areas are most likely due to a lack of natural enemies, pathogens and competitors. In its native area, various natural enemies of OLBs have been identified; however, little is known about the occurrence and impact of OLB pathogens. None of the pathogenic fungi found on OLBs in natural conditions have been identified until now. In this study, we provide evidence of four entomopathogenic fungi that are naturally occurring on invasive OLBs found in infested pedunculate oak forests in eastern Croatia. On the basis of their morphology and multilocus molecular phylogeny, the fungi were identified as Beauveria pseudobassiana, Lecanicillium pissodis, Akanthomyces attenuatus and Samsoniella alboaurantium. The sequences generated for this study are available from GenBank under the accession numbers MT004817-MT004820, MT004833-MT004835, MT027501-MT27510, and MT001936-MT0011943. These pathogenic species could facilitate biological control strategies against OLBs.

昆虫病原真菌鉴定为侵入性橡树花边臭虫（Corythucha arcuata（Say））的自然发生的昆虫（半翅目：ing科）

橡木鞋带臭虫（Crythucha arcuata（Hemiptera：Tingidae））最早于2000年在意大利北部的欧洲被确认为入侵害虫，此后迅速蔓延，袭击了欧洲国家的大片森林地区。OLB是一种吸吮细胞的昆虫，原产于北美，与栎属spp。作为其主要主机。由于缺乏天敌，病原体和竞争者，它的迅速发展，在被入侵国家的成功建立以及与当地相比对寄主的破坏更多是可能的。在其原产地，已经发现了OLB的各种天敌。但是，关于OLB病原体的发生和影响知之甚少。迄今为止，尚未发现在自然条件下在OLB上发现的致病真菌。在这项研究中，我们提供了四种昆虫病原真菌的证据，这些真菌是在克罗地亚东部受侵染的有花梗的橡树林中发现的侵入性OLB上自然产生的。根据真菌的形态学和多位点分子系统发育，将其鉴定为假小球孢白僵菌，小便Lecanicillium pissodis。，弱链霉和沙膜藻。可从GenBank以登录号MT004817-MT004820，MT004833-MT004835，MT027501-MT27510和MT001936-MT0011943的形式从GenBank获得此研究产生的序列。这些病原体可以促进针对OLB的生物控制策略。
