Pest Profile: Spotted Lanternfly

We have seen many high-profile examples of insect invasions, and as gardeners, we have probably come across some of these species in our very own landscapes and experienced their impacts first-hand.

If you live in the Eastern part of the United States, you have probably already heard about one of these invasive insect species that is currently wreaking havoc. The Spotted Lanternfly (SLF), Lycorma delicatula, is a 1 inch long planthopper native to China, and has since spread to Japan, South Korea, and the United States.… Continue reading this article “Pest Profile: Spotted Lanternfly”

When Plants Attack! (each other)

When you talk about killer plants, your mind may conjure images of a man-eating plant in “Little Shop of Horrors,” insect-eating Venus flytraps or poisonous plants like deadly nightshade.

While all of those scenarios are interesting in and of themselves, what about plants that attack other plants?

I’m talking, of course, about parasitic plants. These plants thrive on stealing nutrients from other plants, either weakening them or, quite possibly, killing them.

Parasitic plants connect themselves to a host plant and siphon off the sugars that plant produces and the nutrients it pulls from the soil.… Continue reading this article “When Plants Attack! (each other)”

You think YOU had a bad day…!?!

Just downloading some photos from the end of the summer, and found this. Rarely can I work up sympathy for a tomato hornworm (Manduca quinquemaculata). Though the moth is quite lovely, the caterpillars really did a number on my tomatoes (and two spindly eggplants) this year, and I recall joyously taking this photo in August.

However, I’ve had a rough Monday, and can kind of relate to being covered in Braconid wasp pupae. The larvae have chewed their way through the caterpillar, to spin their grisly cocoons of death (would have made a great post a couple of weeks ago) and dangle there in the breeze until emerging.… Continue reading this article “You think YOU had a bad day…!?!”

Beetlemania

File this under “if it’s not one thing, it’s another.”
Which may be, upon further reflection, the most profoundly absurd statement ever when it comes to gardening. It’s nature! Of course there’s always something!
Here in the Blue Ridge mountains of Virginia, we’ve had insect pests come and go, with each summer featuring something different.

Two years ago? Chewing up everything in the vegetable garden plus lots of perennials… Blister beetles!

Last year we had record rainfall, which brought out the gnats in gnumbers we’d never seen before.… Continue reading this article “Beetlemania”

Garden Professors – More Efforts on Your Behalf

We’re out there for you, our loyal readers. 

Debunking myths, reviewing the literature, setting people straight, battling blister beetles, flying in balloons… and taking out those pesky deer, one at a time.

Yes, indeed, that is fur in my windshield.

So that’s why they’re called blister beetles…

I’ve had several discussions with gardening folks in the region on one of our more annoying pests, the blister beetles.  Big appetite, eats lots of things we value, and darned hard to get rid of.  Someone invariable says “yep, they bite, too” and “be careful – you’ll get blistered.” However, I’ve yet to hear any first-hand experience with the personal-injury aspect of blister beetles.

I’ve suffered from the heartbreak of blister beetles for two summers in a row. … Continue reading this article “So that’s why they’re called blister beetles…”

Everything is obvious once somebody shows you…

It’s amazing how many things in life seem complex when we try to figure them out for ourselves but then we end up smacking ourselves on the forehead when someone shows us how simple it really is.  The infield fly rule comes to mind.  Some colleagues of mine here at Michigan State may be on their way to such a solution for the problem of white grubs in lawns.  Drs. Dave Smitley (Entomology), Kurt Steinke, and Trey Rogers (Crop and Soil Science) are investigating the effect of mower height on turf damage from grubs.… Continue reading this article “Everything is obvious once somebody shows you…”
