Abstract

The current study reports the first records of an aphid-like pest and leaf pathogen on oak species in Bulgaria. In 2020-2023, leaf samples presenting characteristic yellow spots and lesions were collected from mature trees of Quercus petraea, Q. cerris, Q. frainetto and Q. robur in different localities of the country. Damage caused by oak obligate leaf pathogen Microstroma album, the leaf phylloxera, Phylloxera glabra, and the oak lace bug, Corythucha arcuata were identified on the lower surface of oak leaves. M. album was identified on all studied Quercus species. Angular white patches, the fruiting stage of the fungus, appeared on the lower surfaces of the leaves. P. glabra caused yellowish mosaic discoloration on the leaf surface of Quercus cerris, Q. frainetto and Q. pertaea. Sucking damage displayed a stippled pattern of yellow, brown, or whitish dots. In places where M. album develops, the invasive oak lace bug was often found as the only sucking species on oak leaves, which is most likely also a vector of the disease. Severe damage caused by established both obligate pathogen (M. album) and sucking insect pests (P. glabra, C. arcuata) could result in a weakening of the oak trees. On sufficiently weakened trees, secondary fungal pathogens or boring insects, commonly infested oak trees, can cause their death.
首次记录保加利亚橡树林中的 Microstroma album (Desmazières) Saccardo, 1878 (Basidiomycota: Microstromataceae) 和 Phylloxera glabra (von Heyden, 1837) (Hemiptera: Phylloxeridae)
目前的研究报告首次记录了保加利亚橡树物种上的蚜虫类害虫和叶片病原体。2020-2023 年,研究人员从保加利亚不同地区的栎树(Quercus petraea、Q. cerris、Q. frainetto 和 Q. robur)成熟树上采集了叶片样本,这些样本呈现出特征性黄斑和病变。在栎树叶片的下表面发现了栎树叶片固有病原体白微囊螨、叶枕蚜和栎树花边蝽造成的损害。在所有研究的栎树品种上都发现了槲皮螨。叶片下表面出现角状白斑,这是真菌的子实体阶段。P. glabra 在柞树、栎树和栎树的叶片表面造成淡黄色马赛克褪色。吸食损害显示出黄色、棕色或白色小点组成的条纹图案。在栎树花边蝽生长的地方,入侵的栎树花边蝽往往是栎树叶片上唯一的吸食物种,很可能也是病害的传播媒介。已确定的病原体(白粉病菌)和吸食性害虫(P. glabra、C. arcuata)造成的严重损害会导致橡树衰弱。在树势充分衰弱的情况下,常见于栎树的次生真菌病原体或蛀虫会导致栎树死亡。
