Briefings

Researchers report a new pest outbreak of the wheat stem sawfly in Colorado's Eastern Plains, which has shifted its preference from native grasses to wheat, causing $70 million annual losses. The insect has spread across the state's agricultural fields, threatening the state's top wheat crop. The article notes the pest's recent adaptation to wheat, which is the foundation for bread and pastries, but does not specify the exact date of the initial pest arrival or the specific number of infested acres beyond the general impact of the pest.

Key points

• The wheat stem sawfly has spread across Colorado's Eastern Plains, shifting its preference from native grasses to wheat.
• The pest causes $70 million in direct and indirect losses annually to Colorado's top agricultural commodity, wheat.

Context

Colorado's Eastern Plains are a major agricultural region where wheat is the foundation for flour used in bread, noodles, and pastries. The pest's shift to wheat has caused significant economic damage, making this a critical issue for the state's food security and agricultural economy.

Limitations

The evidence does not specify the exact date the pest arrived in Colorado or the precise number of infested acres. It also does not provide details on the specific number of sawfly larvae or the exact timeline of the pest's spread across the state's Eastern Plains.
