New K‑State Extension publication helps identify and manage European pine sawfly

K‑State Extension bookstore has released a new publication to help people who care for pine trees identify and manage European pine sawfly. European pine sawfly is an insect pest whose larvae feed on older pine needles below new growth, potentially ruining their aesthetic appearance.

European pine sawfly, also known as Neodiprion sertifer, has larvae that look like caterpillars, but they are actually related to ants, bees and wasps, which is an important distinction when considering management methods.

The two‑page, full‑color publication explains the sawfly’s biology, the damage it causes and how to scout for problems early. It also includes management options, such as removing larvae by hand, using a strong spray of water and applying insecticides when needed.

The publication, European Pine Sawfly: Insect Pest of Pine Trees (MF3735), is available to read or download for free from K-State Extension Bookstore.
