We had the Polyphagous Shot Hole Borer (PSHB) in Poplar trees at the Del Amo on ramp to the 710 south bound. PSHB was collected on site. The trees were felled, chipped, and tarped on site.

I am 95% sure these bugs have killed a pine tree on Raymond Hill in South Pasadena.. I have found insects flying into my apartment adjacent to the tree that match the description and photos of the insect.

I have a Kwanson(sp?) Cherry tree in my back yard that appears to probably be this pest. The tree was healthy last year but this spring failed to leaf out and has by now apparently been fully infested. I have another such tree in my front yard and so far I see no evidence of similar infestation.

I have a California Sycamore that is fully engulfed and a large 85 year old Califoria Live Oak that was transported from Elsinore in a coffee can (as a pup) which is losing large branches in spite of spraying and seemingly the best preventative care. It's sister next to it (7 feet away) isn't sharing the disease yet but may be not be suffering from a swimming pool dug fairly (who can say)to the infected one's drip line. If you hear any thing that seems to work please email above.

I have a mature Mango tree that was identified as having the polyphagous shothole borer (PSHB). The tree looks very healthy. I just recently noticed the holes and sapping. Called an arborist to find out what the holes were on my tree. NW FULLERTON

I have a 20 foot Brazilian pepper tree that is not dead. It has an infection of beetles. Apparently, they are box hole borer bettles. The tree will be removed next week. There are 2 more trees next to it that are ok.  
I live in Dana Point. Our area has many trees (Danawoods hoa) I am concerned about my citrus trees.
