In June of 2011, Robert Jetton (NCSU Camcore) and Fred Hain (NCSU Department of Entomology) received a $45,040 grant from the US Forest Service Southern Research Station for a new research project titled, “Evaluating Techniques for Artificially Infesting Hemlocks (Tsuga spp.) with the Hemlock Woolly Adelgid (Adelges tsugae) and Assessing Variation in Adelgid Susceptibility Among Carolina Hemlock (T. caroliniana) Half-sib Families.”

The Alliance for Saving Threatened Forests (ASTF) is hosting a one-day (9a.m.-5p.m.) symposium reporting on host resistance research to the hemlock and balsam woolly adelgids.  The conference will take place October 26^th at the Haywood County Extension Center, across from the Mountain Research Station (MRS) in Waynesville, NC. The day will include an afternoon tour of ASTF activities on the MRS facility.  The objectives of the conference are: 1) To bring together scientists researching adelgid resistance to discuss  their most recent findings in laymen’s terms.  2) To educate the public and the media about the work of ASTF and the potential for restoring hemlocks and firs.  3) To attract potential donors for support of the ASTF mission.  We invite you to attend this conference so that we can develop a stronger partnership to save our forests. The symposium is being sponsored by the Friends of the Smokies, the NC Nursery and Landscape Association, and the NC Christmas Tree Association. To register for the symposium, click here:

ASTF is partnering with Share Our Shoes, also known as “SOS”, for our upcoming 5K!

SOS is a shoe charity dedicated to helping those in desperate need of shoes. There are billions of shoes sitting in closets nationwide and there are millions in the world who have never owned a pair of shoes… doesn’t seem right, does it?  We’ll have bins set up at the race so bring your gently used shoes to donate!  You can also donate the shoes off of your feet after the race, dedicated to those walking barefoot without a choice.  To find out more about SOS, visit www.ShareOurShoes.org

When: October 16, 2011 at 2:00 pm

Where: NCSU Centennial campus

Details: All participants will receive a pint glass and both the first place male and female runners will receive two cases of beer from LoneRider!

Questions: Contact Erin Mester at ecmester@ncsu.edu

HWA Presentation from Rhode Island (PDF) (33 MB file)

This presentation illustrates some of our findings on existing host resistance to hemlock woolly adelgid in native hemlock stands and exotic hemlocks. The author, Kelly Oten, graduate research and teaching assistant, won third place for the presentation at the student competition during the Southeastern Branch Entomological Society of America meeting this year.

HWA resistance PDF for ASTF website (PDF file) (This will open the presentation in a new window, so you can read the presentation and look at the comments to see what each slide is about)

Comments for slides:

Slide 5:  Since the hemlock woolly adelgid (HWA) is wingless, it must be transported passively, on the bodies of birds and/or deer or via the wind.  Therefore, the adelgid’s ability to location its habitat and host are not in its control.  We are interested in the acceptance of the feeding site, in this case the base of the hemlock needle, of HWA.  The next slides will detail out investigations into how the feeding site is selected by HWA.

Slide 6: We are interested in understanding host acceptance because it has implications for host plant resistance.  Know the characteristics to look for in resistance trees will make for rapid identification of resistant trees in naturally occurring stands as well as screening for resistance in breeding programs.

Slide 7:  Trichomes are sometimes used as defense to herbivores; these images show eastern hemlock (T. canadensis) covered in trichomes, indicating that trichomes do not deter HWA feeding.

Slide 8: We investigated the thickness of the layer HWA must penetrate to feed.  This is currently inconclusive; our future plans are to inspect Chinese hemlock.

Slide 11: The next three slides show sensillae that will be looked at under higher magnification.  Investigating the morphology of sensillae may give us a clue as to their function.

Slide 15: Please view the video posted below.  This shows the selection of the feeding site by HWA.
