Differential Susceptibility of Six Euonymus Species and Cultivars to Euonymus Scale, Unaspis euonymi (Comstock)
Journal of Environmental Horticulture, 1995Co-Authors: David K. Jefferson, Peter B. SchultzAbstract:Abstract The susceptibility of Euonymus species and cultivars to infestation by Euonymus scale was studied in both field-grown and container plants. Significantly lower levels of Euonymus scale were observed on Euonymus kiautschovicus ‘Manhattan’, E. japonicus, and E. fortunei in the field studies. In contrast, E. japonicus ‘Albo-marginatus’ and E. japonicus ‘Microphyllus’ had the highest infestation levels, indicating greatersusceptibility to Euonymus scale. In container studies, E. japonicus ‘Albo-marginatus’ was the most susceptible of the species and cultivars; however, none of the remaining 5 differed significantly from one another

Distribution of Natural Enemies of Euonymus Scale, Unaspis euonymi (Comstock), in Virginia
Journal of Entomological Science, 1995Co-Authors: David K. Jefferson, P. B. Schultz, M. D. BryanAbstract:The colonization of Chilocorus kuwanae (Silvestri) (Coleoptera: Coccinellidae) and Cybocephalus nipponicus (Endrody-Younga) (Coleoptera: Nitidulidae), introduced predators of Euonymus scale, Unaspis euonymi L., was evaluated on evergreen Euonymus scale, Euonymus japonica L., by regional and statewide surveying. This study determined the statewide distribution of the native parasites of Euonymus scale, Aspidiotiphagus spp. and Encarsia spp. (Hymenoptera: Aphelinidae). Highest recovery incidences were from 18 of the 41 survey sites on 25 May. The survey established the survival and dispersal of C. kuwanae in metropolitan areas of Virginia with recoveries in 8 of the 12 cities.

Full genome sequence of a novel potexvirus from Euonymus bungeanus Maxim based on RNA-Seq analysis.
Archives of virology, 2019Co-Authors: Caixia Yang, Li Liang, Qiushi Hou, Junzhu Wang, Shuang Gang, Song Zhang, Mengji CaoAbstract:In July 2018, a yellow mottle leaf disease was observed on the leaves of Euonymus bungeanus Maxim plants in Liaoning Province of China. Typical flexuous filaments (diameter, 13 nm; length, ca. 500 nm) were observed in extracts on the symptomatic leaves. Transcriptome sequencing indicated the presence of a potexvirus in the infected samples. The complete viral genome, determined to be 6,784 nucleotides in length, excluding the poly(A) tail, contains five open reading frames and is most closely related to that of Euonymus yellow vein associated virus (EuYVAV, MF078061) (41.0%). Based on the coat protein gene, this virus shares the highest sequence similarity with cymbidium mosaic virus (CyMV, EF125179), with 43.9% nucleotide and 38.8% amino acid sequence identity, respectively. Phylogenetic analysis indicated that the virus clustered with potexviruses and is most closely related to EuYVaV. This virus is a distinct member of the genus Potexvirus, for which the name "Euonymus yellow mottle associated virus" (EuYMaV) is proposed.

Characterization of the complete genome of Euonymus yellow vein associated virus, a distinct member of the genus Potexvirus, family Alphaflexiviridae, isolated from Euonymus bungeanus Maxim in Liaoning, Northern China.
Archives of virology, 2017Co-Authors: Caixia Yang, Tong Han, Liao Yiming, Sha ChenAbstract:In August 2016, a yellow vein disease was observed on leaves of Euonymus bungeanus Maxim (Euonymus, Celastraceae) in Liaoning, China. Virions measuring 750 × 13 nm were observed in a sample from the diseased plant. A potexvirus was detected in the sample by small-RNA deep sequencing analysis and recovered by traditional cloning. The genome of this potexvirus consists of 7,279 nucleotides, excluding the poly(A) tail at the 3’ end, and contains five open reading frames (ORFs). Based on the nucleotide and amino acid sequences of the coat protein gene, the virus shared the highest sequence similarity with white clover mosaic virus (WCMV, X16636) (40.1%) and clover yellow mosaic virus (ClYMV, D00485) (37.1%). Phylogenetic analysis showed that the virus clustered with potexviruses and is most closely related to strawberry mild yellow edge virus. These results indicate that this virus is a distinct member of the genus Potexvirus, for which the name Euonymus yellow vein associated virus (EuYVAV) is proposed. To our knowledge, this is the first report of a potexvirus on E. bungeanus.
