Worcester commission notes arrival of spotted lanternfly; staff shares state guidance, limited municipal response planned
Loading...
Summary
Staff shared MassDAR materials after local detections of spotted lanternfly. The commission discussed monitoring, treatment in managed parks, and the likely role of state and federal agriculture agencies if commercial orchards are affected.
Commissioners were briefed on the detection of the spotted lanternfly in Worcester and received informational materials from the Massachusetts Department of Agricultural Resources (MassDAR) during the Oct. 9 meeting.
Rob, the parks staff liaison, said the department had placed the MassDAR management guide and a flyer on the commission agenda to help commissioners answer constituent questions. “If we come across it in a public park, and we’re in there doing cleanup, we’ll deal with it there,” he said, but added the city does not have resources to undertake broad removal on private property or across right-of-way.
Commissioners asked whether the city planned systematic removals of tree-of-heaven (Ailanthus altissima), a preferred host. Rob said the city would not undertake widescale removals at present and noted many established specimens are 50–60 feet tall; the managed park stock appears largely free of infestation to date. He indicated that stronger state or federal intervention would likely follow if orchards and vineyards show measurable economic damage, at which point APHIS (U.S. Animal and Plant Health Inspection Service) and state agriculture resources would coordinate more active responses.
Commissioners shared anecdotal observations about locally visible “hot spots” and noted research on biological and cultural controls is active; speakers referenced emerging work on attractant plants and natural predators in other states. The commission filed the lanternfly item for follow-up and agreed to circulate MassDAR materials to commissioners and on the commission’s information channels as appropriate.
No regulatory or removal program was adopted at the meeting; commissioners emphasized reliance on state guidance and targeted response when crews encounter lanternfly during routine park maintenance.
