Dear Lawnsite members,

Your post about ground pearl scale insects caught my attention.
I am a graduate student working at the American Museum of Natural History on scale insects, I try to understand their evolution with the plants they infest, that can be very useful for applied fields.

If any of you come through a ground pearl infestation in your garden, could you please contact me directly? Thank you very much.

I am an entomologist but I am based in New York City, at the American Museum of Natural History.

I can identify scale infestations if specimens are sent to me (they require slide mounting to be identified). I am mostly interested in receiving ground pearl insects for later my own research and can provide identification subsequently.

Please let me know if you have people contacting you on that matter.

Thank you.

To whom it may concern, this is the method I found and used after researching it. I found a study that was done(don't ask for a link Kiril. It was 2 or 3 years ago) using this technique and I used it with some success. The study found that by applying Merit along whith a wetting agent, you introduced a systemic insecticide that would hang in the root zone for an extended period. This would allow the turf to more readily take it up through the roots and of course, that's where the "pearls" are attached to the plant. By using tis method, there was no need to try to defeat the hard shell of the pest. They simply ingested it. I eliminated the pests in some cases and in others I signifigantly reduced numbers and kept them under control. I only had 5 or 6 cases out of hundreds of cutomers but I still have access to most of these lawns.

Maybe this one? Not really a study, but it does mention studies (without reference I might add).

I would replace "organized" with "blessed with discretionary time"

I am currently working with a scientist at NC State University on a way I have developed to kill Ground Pearl and so far all the results have been positive. The process is very simple and the effectiveness is undeniable. I am located in Wilmington NC, here the problem is massive. I would like some feedback from other areas in the country to get a feel for how extensive this problem really is.
