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

Egg masses have on average between 30-50 eggs and can be laid on trees or any smooth surface

Egg masses have been found on many different objects and often are well hidden

Egg masses have been found on many different objects and often are well hidden

Immature stages migrate up and down trees/plants each day and are easily caught on tree bands

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!

Outreach

• Signs for municipalities• Compliance training

tools for industry• Compliance tools for

local hunting/gun clubs• Mailings

Removal-Trap Tree MethodMost Ailanthus are removed or killed with herbicide

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

• Found in December 2015

• PA first in US to find and official ID

• 2 generations per year –Spring and Fall
