Topic tags/keywords: zone 7 pear psylla infestation insects pear tree

Anyone have any pratical experience with this little critter? I’ve only just discovered it, though the sap from whatever it is they do has been rubbing off on me each time I brush the trees for a couple of weeks now. I’ve read that it could kill my trees, and I’m generally against that.

Thanks for any advice!

From a University of California Intigrated Pest Management Program publication.

DESCRIPTION OF THE PEST
Pear psylla is one of the most serious insect pest of pears because of its ability to develop resistance to insecticides and vector the pathogen that causes pear decline.

I have never encountered this pest, good luck with finding a solution.

God, I thought you said “Pearzilla”....I was horrified! No, never seen these creatures. Good luck with eradicating them, though! I am picturing all sorts of war movies…

A local, very reputable nursery has suggestions for me, but it involves spraying the trees. Didn’t write down what it was as I’m going to go talk to them to, but I remember him saying it isn’t harmful to mammals, but you want to wait a week before picking and eating anything, even from the nearby veggie garden. This means, of course, that it will likely kill all other insects on the tree, including beneficial ones. Arrrrggghhh!

Well, I haven’t sprayed anything yet, but I’ll likely do some sort of dormant oil, but it appears that Mother Nature has been helping a bit. Seems wasps of a particular kind or two find these critters very tasty, and have seemed to maybe saved the trees – at least saved me from spraying some nasty stuff.
