Along the Rio Grande in Texas, tiny insects are taking a big bite out of an invasive weed that competes for limited water resources vital to agriculture and native vegetation. Several years ago, ARS scientists released two insect species as part of a biocontrol program to kill giant reed (Arundo donax).

Emerald ash borer (EAB) is an invasive insect from Asia that kills ash trees. EAB was first detected in North America in 2002. Several tiny wasp species are helping to control EAB.

The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has analyzed the potential environmental impacts of releasing a parasitoid wasp to biologically control the Russian wheat aphid. The Russian wheat aphid is a wingless, pale yellow-green or gray-green insect lightly dusted with white wax powder that feeds and develops on grass and cereal species. The biological control agent is a small, stingless wasp called Aphelinus hordei that can be used to reduce the severity of damage caused by Russian wheat aphids. Based on our assessment and other relevant data, releasing this biological control agent will not have a significant impact on the quality of the human environment. APHIS invites the public to review and comment on the environmental assessment until June 4, 2020, 30 days after publication in the Federal Register on May 5, 2020.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is accepting comment on an environmental assessment (EA) that addresses the environmental impacts of releasing the insects Bikasha collaris and Gadirtha fusca to biologically control the invasive Chinese tallow tree (Triadica sebifera) in the contiguous U.S.

APHIS is making the EA available to the public for review and comment for thirty days starting on Jan 21, 2021. We will consider all comments that we receive on or before Feb 22, 2021 at: https://www.regulations.gov/docket?D=APHIS-2020-0035.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has issued the final environmental assessment (EA) for releasing Japanese knotweed psyllid (Aphalara itadori) to manage Japanese, giant, and bohemian knotweeds (Fallopia japonica, F. sachalinensis, and their hybrid, F. x bohemica). After careful analysis, APHIS has determined that releasing Japanese knotweed psyllid within the continental United States is not likely to have a significant impact on the environment. Based on this determination, APHIS will not prepare an environmental impact statement and will begin issuing permits for the release of Japanese knotweed psyllid.

The U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) is accepting comment on an Environmental Assessment (EA) that addresses the environmental impacts of releasing Asian leaf beetle (Lilioceris egena) to manage air potato (Dioscorea bulbifera). After careful analysis APHIS has determined that the release of Asian leaf beetle within the continental United States will likely not have a significant impact on the environment. Air potato is a twining vine that can reach lengths of more than 65 feet and is capable of climbing and out-competing native vegetation.

APHIS will review and consider all public input submitted during the 30-day comment period and use the information to complete a final environmental assessment. Members of the public can review and comment on the assessment Jan 8, 2021 by accessing it and supporting documents here: https://www.regulations.gov/docket?D=APHIS-2019-0068. This action will go into effect on Feb. 8, 2021, 30 days after publication in the Federal Register.

This guide provides photographs and descriptions of biological control (or biocontrol) agents of insect, disease, and weed pests in North America. It is also a tutorial on the concept and practice of biological control and integrated pest management (IPM). Whether you are an educator, a commercial grower, a student, a researcher, a land manager, or an extension or regulatory agent, we hope you will find this information useful.
