![]() ![]() Whatever banding method is used, bands should be monitored on a regular basis (at least once a week). To limit this type of capture, a narrower band can be used to limit the surface area that is contacted by the larger animals or a cage made of chicken wire can be used to limit unwanted captures. However, when choosing the type of band to use, its stickiness is an important consideration as the use of stronger sticky bands can bring the unwanted consequences of capturing beneficial insects and pollinators, squirrels, bats and birds. Stickiness of the band used will determine how effective it is in capturing the various stages of spotted lanternfly.Įarly instars are more easily captured using bands that are less sticky but 4th instars and adults of this pest have shown the ability to walk over a less sticky band, or avoid them entirely. Because of this movement, sticky bands have been found to play a part in the monitoring and management of this pest.Īccording to work done in the quarantine zone in Pennsylvania, placing bands about 4 feet from the bottom of a tree has captured this insect both going up and coming down. Spotted lanternfly has a habit of moving up and down trees during the day, particularly the first three instars. 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. 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 take advantage of the propensity of this insect, especially the first three instars, to move up and down tree trunks. 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. A piece of vinyl window screening secured above the sticky band, secured with push pins at the top and flared out at the bottom several inches below the band can help prevent unintentional catches of other insects and birds. Sticky band traps encircling the trunk can be effective but they must be accompanied by a barrier to prevent the capture of beneficial insects and animals such as birds. Many egg masses could have been laid in the tree canopy above the trap, and the adult stage can fly into the higher branches without climbing the trunk. Although a trap may catch large numbers of insects it will not completely prevent spotted lanternfly's presence on that tree. The traps are best set by early May to capture the nymphs as they emerge from the egg masses. But they have their favorites, including the tree of heaven ( itself an invasive species) and grapevines.Traps can be useful to catch the spotted lanternfly nymphs and adults as they climb the tree trunk. "They have a pretty diverse palate and can feed on over 100 different plant species," Eshenaur said. "We've updated it twice a week, even just to keep up with all the new counties in the Northeast and out in the Midwest that are having infestations," he told NPR. At that time, the project warranted maybe an update two to three times a year. But they do pose a serious risk to agriculture.Įshenaur, with the New York State Integrated Pest Management Program, said he and his team started monitoring the spotted lanternfly in 2018. These insects are not dangerous to humans or pets - they don't bite or sting, and they aren't venomous. ![]() Recent reports indicate the bugs have settled in New York, Canada, Maryland, Virginia and North Carolina, and now, according to Brian Eshenaur, they have migrated over to the Midwest. ![]() A spotted lanternfly creeps on the ground during a baseball game in Pittsburgh in 2021.Įver since the spotted lanternfly first appeared in Berks County, Pa., in 2014 (arriving from its home in Asia), this invasive species has been booking it across the United States.
