This is a preliminary list compiled by Dr. Paul Weston, Woody Plant Entomologist, Cornell University. It reflects our experiences so far. Just because a species is listed as most resistant doesn't mean that it won't be infested.
Highly susceptible species are the first to be attacked, and are generally destroyed in the first 2-3 years following infestation.
Susceptible species are eventually destroyed, but usually are not heavily fed upon until the most susceptible species are eliminated.
Moderately susceptible species show varying degrees of susceptibility, but usually are not destroyed by the beetle.
Resistant species show little or no feeding damage, and survive infestations rather well. Most species in all susceptibility groups exhibit more feeding damage when grown in the shade.
Highly susceptible:
- V. dentatum complex, arrowwood viburnums
- V. nudum, possum-haw, smooth witherod viburnum
- V. opulus, European cranberrybush viburnum
- V. opulus var. americana (formerly V. trilobum), American cranberrybush viburnum
- V. propinquum*, Chinese viburnum, Taiwanese viburnum
- V. rafinesquianum, Rafinesque viburnum
Susceptible:
Moderately susceptible
- V. alnifolium (syn. V. lantanoides), hobblebush
- V. burkwoodii, Burkwood viburnum
- V. x carlcephalum, Carlcephalum viburnum
- V. cassinoides, witherod viburnum
- V. dilatatum, linden viburnum
- V. farreri , fragrant viburnum (except 'Nanum', which is highly susceptible)
- V. lantanoides (syn. V. alnifolium), hobblebush
- V. lentago, nannyberry viburnum
- V. macrocephalum, Chinese Snowball Viburnum
- V. x pragense, pragense viburnum
- V. prunifolium, blackhaw viburnum
- V. x rhytidophylloides, lantanaphyllum viburnum
- V. tinus*, laurustinus viburnum
