Survival and development of Lycorma delicatula (Hemiptera: Fulgoridae) on common secondary host plants differ by life stage under controlled conditions

Host range assessment for emerging invasive insects is a vital step toward fully defining the issues insect may pose. Spotted lanternfly (SLF) an species that rapidly expanding its presence in United States. The primary hosts facilitating this spread are tree of heaven, plant from SLF’s native range, and economically important winegrape. Black walnut also implicated as common host plant. This study investigated survival development SLF on diets included variety crop plants or absence heaven. following species, ‘Honeycrisp’ apple, ‘Reliance’ peach, silver maple, heaven were paired with winegrape black throughout study. had strong high diet alone, Survival parameters reduced all other pairings. In particular, peach treatment did not develop past third nymphal instar. A second experiment evaluated early late instar nymphs adult life stages three specialty crops – ‘Cascade’ hops, muscadine grapes, kiwifruit over two-week period. Nymphs survived longer than adults, first hops differing control treatment. stage best kiwi grape. Our results show only single sufficient complete development, while require additional nutritional quality survival.
