White Pine Weevil Adults Become Active During the Early Weeks of Spring

Many arborists & landscapers often find it difficult to prevent white pine weevil pests (Pissodes strobi), because they are typically applying fertilizer & dormant oil treatments during the control window. In NJ, the control window against feeding white pine weevil adults occurs in March & April. Adults overwinter in the duff beneath trees. The WPW adults will often crawl or sometimes fly to the top terminal leaders of pine, spruce, or Douglas-fir trees. Eastern white pine & Norway spruce species are the most severely attacked & the death of the terminal leaders of these trees will often occur.

Often by July, an infested terminal will brown & die as the weevil larvae have destroyed the vascular tissues. (Photo Credit: Steven K. Rettke, Rutgers Coop. Ext.)

Treatment timing is critical with this pest, and controlling the adult female before egg laying is necessary. Apply preventative sprays (e.g., pyrethroids) only to the terminal leaders during this time. Before mating & egg laying, adults will feed by chewing holes within the central leader, causing a characteristic pitch flow that becomes white when dry. Then females will lay eggs in new cut-out holes within the top 12 inches of the leader just below the terminal bud.

White pine weevil adults will feed within the upper terminal leaders & cause pitch flow that when dries has a white appearance. This is an early symptom that adults are active & control materials need to be applied. (Photo Credit: Steven K. Rettke, Rutgers Coop. Ext.)

February 10th – Hands on Growing Degree-days. We are going to sit down with computers (I have 10+ laptops), our cellphones, and a tablet to see how easy it is to use GDD calculators. We will then compare with the Rutgers Pest Scouting Guides (this is the guide;  https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2023/03/LONT-PSG-DISTRIB-2023.pdf)
  • Like the idea of using growing degree-days, but are unsure how to use the online calculators or other resources – THIS IS FOR YOU. On Monday 2/10 – we will be using laptop computers (I have 12 on-site), tablets, and smart cellphones to access and explore online growing degree-day calculators. We will then use the Rutgers Pest Scouting Guides to line up when to expect these pests and will discuss treatment opportunities with overlapping pest populations.

    -Each person will use all three technology methods to obtain their local growing degree-days. – By the end of the training you will be able to access and utilize this powerful tool anywhere.
February 24th – 2025 Playbook: We will be discussing emerging threats like Box Tree Moth and numerous plant diseases we need to be prepared for. The session will conclude with a 30-minute CORE credit session. 1 unit – CORE obtained-only.
Note you don’t HAVE to be from southern NJ, however I would appreciate you being with a nursery or other commercial ornamental operation. I just want to facilitate thoughtful communication. Registration greatly appreciated.
