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.

A North Dakota Emerald Ash Borer First Detector Program has been cooperatively developed by the North Dakota Forest Service, North Dakota State University, North Dakota Department of Agriculture, National Plant Diagnostic Network and the USDA APHIS Plant Protection and Quarantine to train citizens of North Dakota to correctly identify symptoms and signs of EAB. If you are interested in becoming an EAB first detector in North Dakota, contact Aaron.D.Bergdahl(at)ndsu.edu. Also available is the 2014 Emerald Ash Borer First Detector Manual (PDF | 33.7 MB).

Palmer amaranth (Amaranthus palmeri), an aggressive pigweed species similar in appearance to waterhemp, has been positively identified for the first time in North Dakota in McIntosh County. Palmer amaranth is native to the southwestern U.S. but was accidentally introduced to other areas and has devastated crops in the South and Midwest. It had not been identified in North Dakota until now. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on Palmer amaranth and other noxious and invasive weeds is available here. To report a suspect plant, contact the North Dakota Department of Agriculture at 701-328-2250 or North Dakota State University Extension at 701-231-8157 or 701-857-7677.

As of Jul 2011, New Hampshire has banned the importation of untreated firewood without a commercial or home heating compliance agreement. Firewood is a major source of damaging insects and diseases. This ban will help protect the health on New Hampshire's forests.

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.

Palmer amaranth (Amaranthus palmeri) and houndstongue (Cynoglossum officinale L.) have been added to the state noxious weed list. Palmer amaranth is an aggressive pigweed species similar in appearance to waterhemp and was first found in the state last year. It has now been found in five counties. Houndstongue, which does not spread aggressively like Palmer amaranth, has been found in North Dakota since at least 1911 but infestations have tripled since 2008. It is now found in at least 25 counties. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on these and other noxious and invasive weeds is available at https://www.nd.gov/ndda/plant-industries/noxious-weeds.
