The spotted lanternfly (Lycorma deliculata) was first identified in New Jersey in 2014, having traveled into the state from Pennsylvania. Not really a fly at all, the insect is actually a plant hopper that originated in Asia.
While some people find the insect attractive, others find it to be a bit creepy. But everyone is worried about the spread of the insect since it can infest plants in large numbers, potentially weakening or killing the plant. The spotted lanternfly is a non-native species that can attack a wide range of herbaceous plants and trees. New Jersey’s agricultural growers worry about economic damage to crops, with wine grapes being one crop of concern. Damage to home landscapes is also a worry.
Everyone can help fight the spread of the spotted lanternfly. Homeowners can inspect trees and outdoor items for the insect’s distinctive egg masses and destroy them. Likewise adults and nymphs can be destroyed by chemical or physical methods or corralled with traps. People living in infested areas should inspect their vehicles or any items to be transported for eggs or insects before travelling to areas that are currently free of spotted lanternfly populations. It is helpful to remove tree of heaven (Ailanthus altissima) from your property, perhaps leaving a few to serve as trap trees for the insect. (See the Rettke video below, starting at 56:30.)
You can report sightings of the spotted lanternfly in areas where they are not currently common. Those in Burlington, Camden, Gloucester, Hunterdon, Mercer, Salem, Somerset, or Warren Counties do not need to report sightings. Homeowners can send an email to slanternfly@njaes.rutgers.edu with the municipality and county where the insect was found, and a photo for positive identification. Those working in agriculture can send an email to slf-plantindustry@ag.nj.gov.

Let’s Talk Turkey: the Impact of Food Waste During Thanksgiving
Presented bySara Elnakib, Registered Dietitian and Family & Community Health Sciences Educator for Passaic County.
In the United States, we waste about 30-40% of the food we grow. However, on Thanksgiving Day alone, we waste approximately 172 million pounds of turkey, 40 million pounds of mashed potatoes, and 38 million pounds of stuffing. Waste has social, economic, and environmental impacts. During this session, we will discuss the impacts of food waste, as well as ways to reduce food waste on Thanksgiving and beyond.
