ABSTRACT
This article examines the threat pose by fall webworm to plants. Although the fall webworm has received less publicity than the gypsy moth or painted apple moth, it has a wide host range. This includes northern hemisphere deciduous hardwoods and a wide range of fruit and nut crops. Following the first discovery of the fall webworm, Hyphantria cunea, in 2003, Forest Research entomologist Nod Kay conducted an extensive host-testing study in France. His results show that the unwelcome visitor favours the hardwood species commonly found in Europe and North America, such as oak, maple and elms, putting New Zealand's urban parks and gardens at greatest risk. Overall, the fall webworm showed a similar response to gypsy moth in its acceptance, or rejection of the novel host plants that were offered.
