Getting rowdy at the adelgid dance party
One benefit of very cold spells in winter is that it can kill or limit the spread of harmful pests and pathogens. I don't know yet whether this cold snap is enough to limit two of our major introduced insects, emerald ash borer and hemlock woolly adelgid. Does anyone know?

If you're in the region impacted by #onstorm please check downed hemlock branches for evidence of hemlock woolly adelgid, like in the photo below. You can report sightings on @inaturalist.bsky.social or here www.invasivespeciescentre.ca/invasive-spe...

Adelgid of the week! Adelgid (Gilletteella) cooleyi. Native to western North America, from Yukon Territory to Durango. Introduced in eastern North America, Australia, and Europe.

Living in NC, I can only imagine how hard this problem is even with the best scientists on it
The balsam woolly adelgid obliterated fir trees in the Blue Ridge Mountains, and scientists still haven't figured out a workable-at-scale solution after decades of funded research

2. Though the specific problem here is a orange tree blight.
Gee sure wish we had a great scientific community to work on solving that

I'm just a girl, standing in front of a hemlock woolly adelgid population, asking it how much genetic variation is present.

We covered the adelgid in my Environmental Econ class in undergrad ~20yrs ago, and it had created the "ghost firs" another 20-40yrs before that
The only solution was "pray evolution works things out"
Feels like they're facing a similarly intractable problem here

Beware of Balsam and Hemlock Woolly Adelgid! These two pests harm balsam fir and hemlock trees, severely impacting N. America's Coniferous Forests. Early detection is key to managing their spread. #NISAW #InvasiveSpecies #entomology 🧪 🌎

Pine bark adelgid (unlike the notorious hemlock wolly adelgid) doesn’t typically harm healthy adult trees. Large infestations can make a tree’s trunk appear as if it was covered in snow.

In between the two, at least in NC. The general approach here is to designate a wad of $$$$$ to one of the Research I universities and have them spend as appropriate, along with public-private partnerships. For the adelgid, that was NCSU's College of Ag + Extension program

I’m always curious what “funding” looks like for this kind of thing. It might be “more funded” than average ecology, but are we talking Stanford CS program funding or 2 full professors, a couple post-docs, and an E series van to carry them and filled out with PhD students and a gas card?

The invasive hemlock woolly adelgid is a serious pest of hemlock trees in North America, and early detection is critical for adequate response. Researchers in Canada have developed a wide funnel trap that can detect infestations up to three years before they become visually evident.

This cluster of tiny grey eggs on a Larch twig is that of a Larch Adelgid, Adelges laricis. Many eggs from these clusters have hatched and the nymphs are visible as black flecks on the Larch needles. These were in a Norwich park this evening.
