Red turpentine beetle activity

Head's up! Potential activity from red turpentine beetles has been reported from an IPM scout (and thanks for that lead!). The link goes to a USDA Forest Service resource. Robin

"Watch for Red Turpentine Beetle!

Looking at some Pinus nigra last night and found piles of sawdust/frass near the base with holes just above it.  Have yet to catch the adult, but it sure looks like the trees are being attacked by Red Turpentine Beetle."

Pale green weevil

They come in droves, these weevils. The pale green weevil is quite attractive, bright metallic green and usually shows up this time of year in the valley. They are frequently caught in flagrante delicto on one of their many host plants such as oak, river birch, or elm. Look for notching on the edges of leaves. They are mostly not a problem, their damage largely cosmetic, except on smaller plants or on lead terminals, which cannot tolerate much leaf feeding. A bit of information and images can be found at the link. Robin
