The following is a guest article written by Allison Medrano from CLIP Lawn Care. It is all about the Spotted Lanternfly – very important information for those of you that live in the areas Allison mentions.
You can contact CLIP Lawn Care through their website.
Take it away Allison!
SLF presents a significant threat to Pennsylvania agriculture, including the grape, tree-fruit, hardwood and nursery industries, which collectively are worth nearly $18 billion to the state’s economy. This non-native pest attacks grapes, apples, stone fruits, pines, and other species.
SLF is on the move in Pennsylvania and now has been found in Delaware, Virginia, New Jersey, and most recently Suffolk Co. New York. It has also now been confirmed in Maryland.
- October 25, 2018, Maryland Department of Agriculture Press Release: https://news.maryland.gov/mda/press-release/2018/10/25/first-spotted-lanternfly-confirmed-in-maryland/
- In Pennsylvania, SLF has spread into 13 counties.
- A press release issued from the Delaware Department of Agriculture dated November 20, 2017, confirmed the finding of SLF in New Castle County, Delaware.
- SLF was reported and confirmed in Frederick County, Virginia as of January 10, 2018.
- Become familiar with the different life stages of this pest (see below)
- SLF females prefer to lay their eggs on the tree-of-heaven (Ailanthus) but will lay their eggs on
any flatvertical surface, including other trees, stones, vehicles ( moving theminto other areas), outdoor furniture, and many others. Egg masseswill hatch in the spring.
**Both nymphs (immatures) and adults of spotted lanternfly cause damage when they feed, sucking sap from stems and leaves. This can reduce photosynthesis, weaken the plant, and eventually contribute to the plant’s death. Additionally, spotted lanternfly feeding creates a sugary substance called honeydew. This honeydew, in addition to being attractive to ants, wasps, and other insects, is readily colonized by sooty mold, which can cause parts of the plants to become blackened and look unsightly.**
If you live in Maryland and observe any egg masses or insects which look similar to this, please try to collect them, and inform the Maryland Department of Agriculture at (410) 841-5920 or [email protected] as soon as possible (please attach photos if sending an email).
If you live in Pennsylvania, Penn State is conducting a survey to gather information from horticultural growers, field crop farmers, and forest landowners on the potential economic impact of the spotted lanternfly (SLF) on agriculture and forestry.
If you grow field crops, fruit crops, vegetables, nursery crops, Christmas trees, harvest timber, or tap maple tree, Penn State would like to hear from you.
The objective of the survey is to better inform us of potential damage by the SLF and help focus extension and research efforts on managing this pest. We want to find out what crops you grow and how concerned you are about SLF damage
For those growers in the quarantine zone, we’d also like to know about any management practices you are using and any damage you might have experienced. The results of the survey will be used by Penn State Extension and researchers to fine-tune management advice for the SLF and help prioritize future research and outreach activities.
If you’d like to participate, the survey should take you no more than 10-15 minutes to complete. Click on the link to begin the survey: Penn State Spotted Lanternfly Impact Survey
Your survey responses will be confidential, and the data collected will only be reported in summaries. Your participation is voluntary, and you can decide not to answer a given question if you choose.
If you have any questions about the Spotted Lanternfly Impact Survey, please contact Jayson Harper by e-mail at [email protected] or call 814-863-8638.
To stop the spread of spotted lanternfly, the Pennsylvania Department of Agriculture issued a quarantine for counties where the presence of this pest has been confirmed
Life Cycle of Spotted Lanternfly
Summer Update: I applied bifenthrin with my battery backpack sprayer and so far haven’t seen any signs of Lanternflies. I will update this post with further results as the season progresses.
