Grape

Not known to transmit any human or animal pathogens.

Not known to vector any pathogens or other associated organisms. Sooty mold can develop on honeydew produced by L. delicatula, leading to disrupted photosynthesis. This can cause reduced tree growth, death of seedlings, as well as a decline in the quality and yield of grapes.

There is currently no approved trap or lure for this species. Visual survey is considered the most effective method of detection for SLF. Field trials testing the efficacy of brown, sticky tree bands and a methyl salicylate (high-release) lure are ongoing. The band and lure combination are in use as part of the spotted lanternfly emergency response program in Pennsylvania and states with recent detections. The band and lure combination will be considered for inclusion as a CAPS approved method for pest surveillance based on the outcome of field trials and observations from the SLF program.

The approved method for negative data reporting is visual inspection. Note that surveying for egg masses only, for instance when conducting gypsy moth surveys, is not sufficient for negative data reporting. Negative data may be reported if fourth instar nymphs or adults are not found and no feeding damage symptoms are observed when host material is inspected between July and November.

A Climate suitability map is now available. This survey should only be considered in the states with appropriate climate conditions and suitable hosts for this insect.

The map was produced by the SAFARIS Team. SAFARIS is a modeling framework that enables PPQ to quickly respond to emergencies, efficiently survey for pests, and assess potential pest impacts by collecting critical geospatial data and developing predictive models. SAFARIS is developed and maintained by the NC State University, Center for Integrated Pest Management (CIPM) with support from PPQ PERAL.

The SAFARIS team used a climate suitability model for spotted lanternfly occurrence in the continental United States, that was developed by PPQ PERAL and NCSU CIPM, to support CAPS survey planning. The model predicts the suitability of an area for spotted lanternfly occurrence based on the likelihood of favorable climate conditions for the insect occurring using tools and data within SAFARIS. The detailed method used in this assessment is described here.

Lycorma delicatula is very distinctive. The first three instars are black with white spots and the fourth and final instar is red with white spots and red wing pads.

This species is large and striking in appearance. It is not likely to be confused with other species found in the United States.
