As with any pest, invasive or otherwise, an integrated approach to management (IPM) is key to successfully keeping the population in check. Currently, the first tool in the SLF management plan is exclusion of the pest. Spotted lanternfly populations will likely become established in New York, so delaying the infestation provides valuable time to develop management tools needed to implement a successful IPM strategy. With no, or low populations, the use of sticky bands on trees, (especially on tree of heaven), act as both a monitoring and a management tool. Sticky bands take advantage of the propensity of this insect, especially the first three instars, to move up and down tree trunks. If SLF becomes established in an area, sticky bands can’t provide a sole source of management because once they are full, remaining nymphs are far less likely to become stuck. Sticky bands are also less effective on fourth instar nymphs and adults which are either strong enough to walk across bands without getting stuck or avoid them by jumping or flying.
- Sticky bands
- Biocontrol: predators, parasitoids, and entomopathogenic fungi
- Destruction of egg masses
- Insecticides labeled for planthoppers (contact and systemic). A few 2(ee) and 24(c) have been registered for use in NYS along with other products for use on particular plant types.
- Trap trees
- Lures and trap types (none used at this time but being researched)
At the time of this writing (April 2019), there are no infestations of spotted lanternfly in New York State. Therefore, the current best management strategy is:
- Learn how to identify all life stages of spotted lanternfly and when they are present.
- Inspect all items coming from any of the quarantine zones whether it be something that you purchased or arrived with a visitor.
- When visiting a quarantine zone, keep vehicle windows closed, do not park underneath trees or areas where SLF might congregate; if loading trucks or vans, keep door closed except when loading is taking place, inspect your vehicle (inside and out) before departure.
