Boxwood blight is a disease affecting plants in the family Buxaceae including boxwoods (Buxus), Pachysandra, and Sarcococca plants. First detected in the U.S. in 2011, it has since been found in multiple states and provinces from the East Coast to the West Coast. Boxwood blight has now been confirmed on boxwood nursery stock in New Hampshire. New Hampshire nurseries, landscapers, town officials and residents responsible for boxwood plantings should learn the symptoms associated with boxwood blight. Watch for black lesions on stems, "zonate" brown spots on leaves leading to chlorosis, and leaf drop. If boxwood blight is suspected on recently purchased boxwoods, or plants in proximity to recently purchased boxwoods, please contact the Division and collect a sample for analysis by the UNH Plant Diagnostic Lab.

The Asian Longhorned Beetle (ALB) was found in Worcester, MA in August 2008 and in Boston in July 2010. This insect pest poses a serious risk to trees and forests. ALB has not yet been found in New Hampshire. Help us by looking at the debris from your swimming pools. Whenever you clean your pool, look at the debris you collect in your filter and skimmers. Use this fact sheet (PDF | 1.22 MB) to compare collected insects to common insects. Upload pictures of any insect you think is a longhorned beetle.

Although Asian gypsy moths are not established in Oregon, they were detected in the summer 2015 in Forest Park, North Portland and in Washington state. Since the Asian gypsy moth was just detected recently, we have a unique and small window of opportunity to ensure the population does not become established in Oregon. If we are able to terminate any early infestations of gypsy moth caterpillars that hatch this coming spring, then we can avoid the species establishing a population in our forest. To help respond to the AGM situation, the Oregon Forest Pest Detector program organized several AGM monitoring workshops in spring 2016 for community members and OFPD program graduates. You can also access the AGM presentation (PDF | 3.4 MB) from the workshop to learn more about the AGM management plan, egg mass identification, and visual survey.

As of February 2015, brown marmorated stinkbug (BMSB) has been confirmed in 20 New Hampshire towns/cities. With the exception of a confirmation on nursery stock (shipped several months earlier from Long Island, NY), no specimens have yet been found on any crop. The vast majority of specimens have been found on or in buildings. We need your help. We want to find out where BMSB occurs in New Hampshire. Let us know if you see this species in or on your New Hampshire home. Verbal descriptions are not much use, but clear, close-up photos or specimens are helpful. We want to track this insect in NH and how it builds in numbers.
