Disease and Insect Resistant Ornamental Plants: Viburnum
nysipm.cornell.edu 2018 hdl.handle.net/1813/56379 Disease and Insect Resistant Ornamental Plants Mary Thurn, Elizabeth Lamb, and Brian Eshenaur New York State Integrated Pest Management Program, Cornell University VIBURNUM Viburnum pixabay.com Viburnum is a genus of about 150 species of de- ciduous, evergreen and semi-evergreen shrubs or small trees. Widely used in landscape plantings, these versatile plants offer diverse foliage, color- ful fruit and attractive flowers. Viburnums are relatively pest-free, but in some parts of the US the viburnum leaf beetle can be a serious pest in both landscape and natural settings. Potential diseases include bacterial leaf spot and powdery mildew. INSECTS Viburnum Leaf Beetle, Pyrrhalta viburni, is a leaf-feeding insect native to Europe and Asia. In North America, the beetle became established around Ottawa, Canada in the 1970’s and was first detected in the United States in Maine in 1994 and in New York in 1996. It has since spread through much of the northeastern US (15). Reports of viburnum leaf beetle in the Midwest include Ohio, Michigan, Wisconsin and Illinois (1) and Washington and British Columbia, Canada in the Pacific Northwest (7). The beetle is host-specific and feeds only on Viburnum, but there are preferences within the genus (6). Species with thick leaves tend to be more resistant and feeding is more likely to occur on plants grown in the shade (17). Feeding by both larvae and adults causes tattered leaves and may result in extensive defoliation – repeated defoliations can kill the plant.

Management of the Viburnum Leaf Beetle at the Morris Arboretum Abstract Pyrrhalta viburni (Coleoptera: Chrysomelidae), or the viburnum leaf beetle (VLB), is an invasive pest on viburnums in North America, where native species of the plant have little natural resistance. Resistance can be conferred by leaf texture, leaf chemistry, or a wound response that crushes VLB eggs. The beetle does not immediately kill host plants, but repeated defoliation is fatal after several years. Because viburnum is a common forest and landscape plant in the eastern United States, VLB is a serious concern. The Morris Arboretum has a large collection of viburnums, including many native and non-native species. While VLB had already been observed in passing, this project included a thorough baseline survey of VLB damage throughout the Arboretum. Data were collected for the number of twigs infested with VLB, the number of cavities on each twig, and whether a wound response had been produced. -

Oviposition by Pyrrhalta Viburni (Paykull) on Dead Plant Material: Successful Reproductive Strategy Or Maladaptive Behavior?1
Oviposition by Pyrrhalta viburni (Paykull) on dead plant material: successful reproductive strategy or maladaptive behavior?1 Gaylord A. Desurmont2, Charissa M. Fritzen3, and Paul A. Weston4 Abstract. Viburnum leaf beetle, Pyrrhalta viburni (Paykull, 1799), is a Eurasian chrysomelid recently introduced to North America, where it has become a major landscape pest. P. v ibur ni deposits eggs in the terminal twigs of infested viburnum shrubs, in small cavities that are then covered by the female with a frass-like secre- tion. In the fi eld, fresh P. v ibur ni egg masses are sometimes laid on dead plant mate- rial, prompting the current study to investigate the frequency and proximate causes of this behavior. In the fi eld, P. v ibur ni females were found to lay signifi cantly more eggs on live twigs than on dead twigs, and to lay more eggs on dead twigs that had been infested the previous growing season and contained remains of old egg masses than on non-infested dead twigs. In laboratory choice-tests, females laid signifi cantly more eggs on dead twigs if they contained remains of old egg masses, but did not show preferences between young and old infested twigs. We conclude that the pres- ence of remains of egg masses deposited the previous growing season is stimulatory to P. v ibur ni females and triggers oviposition on dead plant material. Keywords. Pyrrhalta viburni, oviposition behavior, insect-plant interactions, repro- ductive strategy, site selection. 1. Introduction Viburnum leaf beetle, Pyrrhalta viburni (Paykull, 1799), is a chrysomelid belonging to the subfamily Galerucinae and the tribe Galerucini. -

Integrated Control of the Viburnum Leaf Beetle with Minimally Toxic Methods
Title: Integrated control of viburnum leaf beetle with minimally toxic methods Project Leader(s): Paul A. Weston, Senior Research Associate, Department of Entomology, Cornell University, Ithaca, NY Abstract: Viburnum leaf beetle continues to spread throughout the state and region, impacting production and landscape use of several popular species of shrubs (mainly cranberrybush and arrowwood viburnum). If left uncontrolled, this insect kills established shrubs within a few years owing to repeated defoliation by larvae and adults. We evaluated several newer control options that are less toxic than current control tactics, but were expected to provide adequate control. The treatments included horticultural oil applied to egg masses, insecticidal soap applied to larvae, and covering plants with a physical barrier (agricultural fabric) to exclude adults. Insecticidal soap provided excellent control of larvae, but the other treatments were largely ineffective. Experiments with biological control agents revealed that Harmonia axyridis adults released into test plots significantly reduced larval feeding damage, but had no impact on adult feeding or egg laying. Insecticidal soap is now demonstrated to be a viable alternative to synthetic, more persistent pesticides commonly used for control of viburnum leaf beetle, and should have less adverse impact on the environment. Background and Justification: The viburnum leaf beetle (VLB), Pyrrhlata viburni (Paykull), is a leaf-feeding beetle from Eurasia that became established in the northeast in the mid 1990s, and has quickly spread to inhabit portions of all the New England states, New York, Pennsylvania, Ohio, and Washington. Both larvae and adults feed extensively on the foliage of many species of viburnum, killing the most susceptible species within a few years of their arrival. -

Edited Viburnum Leaf Beetle Pyrrhalta Viburni Revised
Fact Sheet (June 5, 2015) Viburnum Leaf Beetle (Pyrrhalta viburni) Prepared by Tom Tiddens, supervisor, Plant Health Care, Chicago Botanic Garden The viburnum leaf beetle (VLB) is a relatively new high-consequence invasive insect that has found its way to Illinois. The VLB damages many types of viburnum, causing defoliation that may lead to death. This insect of great concern, as viburnum is a very common ornamental shrub found in many home landscapes in our area. The VLB is native to most of Europe. It was first found in the United States in Maine in 1994. The VLB was found in Illinois in 2009 (specifically in Cook County). In 2012 and 2013 there were increasing reports in Cook County and the beetle was also found in DuPage County. In 2014 the number of reports increased in Cook County and many reports indicated defoliation in late summer. Some of the 2014 Cook County reports came from as close as Winnetka, only five miles from the Chicago Botanic Garden. Once the VLB becomes established in an area, it is most likely there for good, like the Japanese beetle invasion. Current distribution in United States: Maine, New York, Connecticut, Massachusetts, New Hampshire, Vermont, Pennsylvania, Ohio, Wisconsin, and Illinois (only Cook and DuPage Counties); and let’s not forget Canada, where it first was discovered in North America. The Garden’s Plant Health Care staff and volunteers have been monitoring the Garden’s viburnum collection very closely. On June 2, 2015, viburnum leaf beetle was found for the first time at the Garden. Two separate discoveries were made. -

Pests of Woody Landscape Plants: An Integrated Pest Management Scouting Guide Abstract Effective pest and disease management is a vital part of maintaining Morris Arboretum’s plant collection. The plant protection intern is responsible for scouting the living collection, researching treatment strategies and using integrated pest management techniques to treat infested/infected plants. To facilitate this process, Morris Arboretum is in need of an updated scouting guide that not only lists key Arboretum pests and diseases, but gives detailed information on when and how to scout for these problems and what to do when such problems arise. With the plant protection internship being only a year long, the intern often starts out from scratch each June, with no detailed records or clear-cut timeline for scouting the Arboretum’s living collection. To help solve this problem, I have created a scouting guide outlining ten key pests that frequently affect the Arboretum’s woody plant collection.
