According to Bladmineerders almost any poplar (bladmineerders.nl/parasites/an...) - the psyllids appear to be seldom recorded in the UK so well worth a look! I found them by looking for galls, I think my trees are 'Canadian' Poplar?

Mine keep getting destroyed by psyllids that give the plant bacterial wilt. Spent so much on organic pesticides that don’t even work. Hate these mfers 🤬

David Richmond and various county recorders past and present have put together a set of species guides to particular groups. These can be used alongside other ID resources to help give a picture of Norfolk's wildlife: norfolknaturalists.org.uk/wp/publicati...

Welp, ladybug eggs purchased. Fingers crossed that they arrive soon and can get rid of the psyllids where our pesticides can't reach.
Ngl I'm kinda anxious about when we put them in, since we won't be able to spray anymore. 3-5 weeks of complete vulnerability xwx'

These Leuronota trichiliae show why a lot of folks avoid psyllids. That’s a finger in frame, and if you work with these, you’re expected to dissect the genitalia at this scale. Reliably and repeatedly over many specimens. Irreplicable entomologists.

No worries. There are other species guides on there too including Grasshoppers, Psyllids, Harvestmen, Orchids , mammals, fish, woodlice snd Shieldbugs which are all worth a look too. norfolknaturalists.org.uk/wp/publicati...

Hackberry nipple galls formed by hackberry nipple gall psyllids (one of the jumping plant lice) as part of their life cycles. Flying adults are tiny with pinchy bites as they check to see if you are a hackberry tree. These bites ARE NOT harmful, but they are annoying.

The Tr*mp administration recently fired Jonah Ulmer, a leading USDA expert on invasive pests like thrips and Asian citrus psyllids, so that more farmers may face #citruscanker and the price of OJ continues to increase.

USDA experts have been swept up in the Trump administration’s frenzied and turbulent efforts to drastically shrink the federal workforce.

For your aphid, there is a good Aphid, Psyllids etc group on Facebook. I've also heard good things about influentialpoints.com and that they are quite responsive to emails.

I would have suggested asking department of agriculture for some of the psyllid-eating wasps (that I used to get paid to breed) but I think they stopped that program?? There's no stopping the psyllids really, they are here to drink the plant juice with their impossible smallness

Culturing psyllids in the lab is REALLY hard, so there's not much data on the temperature dependent psyllid traits.

The only scalable intervention in use is heavy pesticides to kill the psyllids that transmit it, and labor-intensive scouting/isolation. It’s challenging to study, but there’s been a very recent potential breakthrough with genetic modification to give the plants natural defense to psyllids.
Researchers explore breakthrough approach to combat devastating citrus greening disease
Scientists at the University of Florida are testing a new type of citrus tree that can fight off the tiny insects responsible for citrus greening.

Those are galls. They result from little insects called psyllids essentially injecting the leaf to induce a growth hormone (oversimplification, but close enough) that the insect then uses as a nest to lay it's eggs. They are pretty much harmless.

Looks like the wasps didn't get *all* of the ladybugs, yay~ I hope that they repopulate soon!
Also I've taken to smacking the remaining wasps with the fly paper we've had to redeploy for the psyllids. It's cathartic.

I’m grateful to @norwichbirder.bsky.social (county recorder for jumping plant lice) for confirming that the Cacopsylla rhamnicola I knocked out of a pine tree in the Brecks earlier this month was the first record for Norfolk.
