Diuraphis noxia (Kurdjumov) (CABI)
Russian wheat aphid (RWA)
Eurasia (Shufran et al. 2007)
First discovered in Texas in 1986 (Michaud and Sloderbeck 2005)
Possibly arrived in wheat imported to Mexico from South Africa (Shufran et al. 2007)
Pest of wheat and barley (Shufran et al. 2007)
USDA. Animal and Plant Health Inspection Service.
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.
