Sawfly larvae on JBP
I have what I think to be sawfly larvae on the needls of my JBP . . . I just noticed them this afternoon on a small branch . . . they look very much like this:
 Any suggestions on getting rid of these guys? I physically removed as many as I can get to, but I know there are more that I can't see. I have readily available a Neem oil spray, but obviously can get my hands on other stuff.

I like Neodiprion sertifer with saltines. They came in via New Jersey 70 years ago.

I usually just hose them off with a stream of water. You can nail them with an insecticide if you like, but they are easy to remove manually. In my experience with these critters, by the time you've noticed them, they've already munched the needles from a branch, so the damage is done.

G'day 007...
If those sawflies were invading my JBP, my first "response" would be a stream of clear water. If "clear water" didn't work, my second "response" would be Carl's Soap Solution, applied according to Carl's directions. If "Carl's Soap" didn't work, my third "response" would be, find the right POISON...a "cide" that is indicated for use ON JBP infected with SAWFLY, and apply according to instructions on the label. It's best to avoid the use of "cides" whenever possible...last resort use, only. It's my learned OPINION that the "first" or "second" "reponse" would do the job...might work for you. Or not. Pat

I have used Bayer's Tree and Shrub Systemic granduals on my JBP for several years now with no problems. For that matter I use it on my Chinese Elms last year and this year as well with no problems.
