Abstract

Lycorma delicatula White (Hemiptera: Fulgoridae) is an invasive phloem feeder with a broad host range that includes both hardwood trees and cultivated temperate fruit crops. Here, we evaluated acceptability of wild hosts, A. altissima and Juglans nigra L. (Fagales: Juglandaceae) and cultivated hosts Vitis vinifera, Malus domestica (Rosales: Rosaceae), and Prunus persica L. Batsch (Rosales: Rosaceae) to L. delicatula under field conditions. Fluorescent-marked early instar nymphs, late instar nymphs, or adult L. delicatula were released at the base of single potted host plants and the number of individuals retained was recorded over 24 h. Paired choice trials with A. altissima and another host plant were conducted. Individuals retained on or moving between plants were recorded over 24 h. Sentinel A. altissima, J. nigra, V. vinifera, M. domestica, and P. persica potted plants were deployed at 5 sites and the number of L. delicatula present on each plant was recorded weekly. In single and paired host trials, early instars and adults were generally retained in higher numbers on A. altissima and V. vinifera, and late instars were retained on A. altissima and J. nigra. Significantly more L. delicatula were present on sentinel A. altissima compared with other host plants, except J. nigra during the period when late instars were the most prevalent lifestage in the field. These results indicate that wild hosts such as A. altissima and J. nigra are likely supporting establishment of L. delicatula populations, and that presence of cultivated V. vinifera may contribute to population establishment and growth.
