Can you detect invasive plants from the air? Yes you can! I mean, it's not as easy as it sounds, but it can be done...

Screwworm imported from Argentina, caught at border inspection in Florida. The interception isn't itself cause for alarm and shows the government is still functioning.

Still, it's a demonstration of propagule pressure, and the re-establishment of screwworm here is likely a matter of when, not if.

Potentially Invasive Spider Spotted at Santa Barbara County Business - edhat A potentially invasive Joro Spider was spotted at a Santa Barbara County business, confirmed the Santa Barbara Museum of Natural History

Good news: they changed it to a Joro! Nice work folks.
Bad news: it looks like some AI generated stuff...

It's one thing to know *what* an #invasivespecies is, and it's another to know *how* to impact real change. This course will teach you the latter, and (we hope) will equate to measurable on-the-gound action to help battle the invasive species problem in the U.S. and abroad. Check it out!

Jorō Spiders: Pretty, Big, and Not Very Bitey Two new studies offer good news about Jorō spiders: Common spider control products are effective against them, and their bites are both unlikely and generally harmless.

Well...it turns out that the stuff in dish soap degrades the cuticle of most arthropods (including beneficial insects). I don't know how long the residue persists from that, but it's not completely safe for non-target stuff. Careful application is key, as you know!

They’re Huge, They’re Creepy, and They’re Back—An Expert’s Tips for Joro Spider Season An entomologist answers your questions about the Joro invasion this fall.

Joro spiders want 3 things: to not be touched or held, to not be in your house, and to not bite you.

I'm not saying that stuff doesn't work (we tried it, and it does) but I'm a state employee so my official company policy is to recommend folks only used labeled products.

Entomologists have been saying this for a while, but new evidence published confirms: Joro spiders are not a major health risk. See original thread for link to research papers

They're definitely negatively impacting native spider diversity. Our team has been conducting our "spider surveys" for 4 years now and there's a clear impact of Joros on native orbweavers: more Joros = less (or often no) native orbweavers. We'll probably publish this info after this season.

Chemical management strategies for the invasive Jorō spider, Trichonephila clavata (Araneae: Araneidae) Abstract. Historically, spider management has received relatively little attention in the literature compared to insect pests, and few studies have examine

Want to get rid of Joro spiders? This #bioinvasion can be managed using commonly available products. Sure, other things work, but please just stick to the labeled stuff (i.e., don't spray machine lubricant all over the place). New #openaccess study in @entsocamerica.bsky.social's JEE provides info.

Keep calm and carry on: bites from Trichonephila clavata are unlikely and cause minimal discomfort Abstract. Arachnophobia is a widespread phenomenon, despite the fact that the vast majority of spiders pose no meaningful threat to people. The introductio

Will Joro spiders (a #bioinvasion in the SE US) bite you, and if they do will it hurt? Turns out they won't bite without a LOT of provocation, and their bites are akin to a mosquito bite - some redness, swelling, and largely gone in a day. Study is #openaccess in @entsocamerica.bsky.social's JME.

Super psyched to have a bunch of our ALB work come out in this special issue! #bioinvasions

Modelling biological processes can be hard, and even harder when scientists and land managers aren't on the same page. We need better communication between these groups, especially with #bioinvasions. Communication matters, y'all.

The boxtree moth was recently found in several new states (MD, VA, WV) and is likely to keep spreading. This #invasivespecies is a recent #bioinvasions that threatens boxwoods - a very common landscape plant. This OA paper in @entsocamerica.bsky.social's JIPM gives a good summary of this pest.

Large chunks of people's favorite trees seemingly go leafless overnight this time of year, usually thanks to caterpillars. Our paper (w/ @kellyoten.bsky.social & #nobluesky Robert Jetton) in @entsocamerica.bsky.social's JIPM highlights several species in the SE US: academic.oup.com/jipm/article...

I agree! I think it's a nice piece of work and it definitely gets read. Thanks for leading the charge!

How do you get rid of invasive Elaeagnus in a forested landscape? We found that you have to get herbicide to the stem or stump because the drooping growth pattern creates an umbrella, preventing good foliar coverage. A simple, yet useful study!
