Viburnum Beetle: A Serious Threat to Viburnum Plants in Stock Blocks, Production, and the Landscape

Robert E. McNiel, Paul A. Weston and Brian C. Eshenaur

pp: 419-421


The genus Viburnum is represented regularly in landscapes from the Canadian border to the Gulf Coast in the Eastern United States. Diverse flowering, fruit, leaf, and form characteristics lead to a range of landscape uses. The diversity in this group of shrubs is botanically described by Krássman (1984). Table 1 lists his nine sections within Viburnum.

Viburnum leaf beetle (Pyrrhalta viburni) is a pest of Viburnum and the insect is now established in the United States. Viburnum leaf beetle, a European native which is established from Great Britain to Italy, was first detected in North America in Ontario, Canada. Since then it is believed to have migrated over land into Maine and across the Niagara Isthmus or St. Lawrence seaway into New York. In New York it was first detected in 1996 along the shores of Lake Ontario.

This work was initiated to learn more about the insect and the extent of damage it causes to viburnums.
