Lycorma delicatula (WHITE):
A Planthopper in the Family Fulgoridae
About 129 Genera, 696 Species in the world
Only 9 Genera and 17 species in North America
Lycorma is represented by 7 species worldwide
Like most planthoppers, Lycorma pierce the stems of plants or trees with their proboscis.

Adults: July 24-DecemberEgg Laying:
October 13-November Eggs: October-June
Hatch and 1st Instar: May 12- June
Second Instar: June 03- JulyThird Instar: June 24-Mid July
One Generation Per Year
Fourth Instar: July 7-September
Adults begin to appear in late summer, feed preferentially on Ailanthus, mate, and lay eggs
In South Korea females lay eggs twice before dying
Males and females mate multiple times
The Pest:
Adults and late instars are rarely caught on bands, but can be easily captured with other active techniques
The eradication program relies on cooperation.
Local officials, state agencies, and extension lead the organizational charge
PDA crews, volunteers, property owners and businesses work in concert
Spotted lanternfly pays the price!

Removal-Trap Tree Method
Though this method targets Adult Lycorma, it
also impacts the immature stages
About 7,484 sites surveyed across the state by Apiary Inspectors, Plant Inspectors and other agencies
PDA extended the state quarantine to 17 Townships in 5 Counties
Similar to gypsy moth quarantine
Citizens self-check
Businesses operate under compliance agreement
2015 Research Highlights:
• Miriam Cooperband, USDA-OTIS: Host volatiles, chipping, trap efficacy
• Rick Turcotte, Craig Larcenaire USFS: Degree Day Study
• Greg Setliff, Kutztown University: Host Range Study
• Mike Saunders, PSU: Impact on Grape
• Julie Urban, NC Nat History Museum: DNA Analysis
• Julie Gould, USDA-OTIS: Parasitoid Studies
• PA DCNR, Bureau of Forestry: Ailanthus distribution
Host Range Study
FIG 1. Brown sticky band on Betula lenta with 2nd instar SLF; FIG 2. Feeding damage on Ailanthus altissima; FIG 3. Egg laying on Salix sp. (cryptic egg masses indicated)
• 3,600+ SLF killed on sticky bands• Bands were effective for capturing 1st–3rd instars only • 24 new North American tree species added to SLF host list • SLF preference for Ailanthus confirmed (compared to other spp.)• 1st-3rd instars as likely to be on non-Ailanthus trees as Ailanthus• Few SLF adults were on non-Ailanthus trees (Aug-Nov); however, large
adult congregations were observed on Ailanthus during this period

agreement with Chinese Academy of Forestry for foreign exploration.
• USDA-APHIS has imported into quarantine Lycorma eggs parasitized by Anastatusorientalis.
• Current emphasis on rearing Lycorma and the parasitoids and initiating
• Dr. Houping Lui, DCNR-PA working on parasitoids found in PA lanternfly populationshostspecificity testing.
Allium Leafminer
• Found in December 2015
• PA first in US to find and official ID
• 2 generations per year –Spring and Fall
• Significant crop loss in onion and leeks
