Cereal Leaf Beetle on Organic Cereal E-Fields Report

Jan. 11, 2024

Our 2023 summer student assistants, Rebecca DiScipio, Kylie Harbert and Stephanie Pflaum were given the opportunity to collaborate with Dr. Ryan H aden (OSU ATI) on a research trial in organic small grains. The objective of this research was to determine if there was a difference in the number of larvae and plant damage in 11 different varieties of organic small grains. Data was collected by counting the total number of larvae per 10 plants in each plot. In addition, damage was also assessed on a visual rating scale. Results indicated that there were significantly less cereal leaf beetle larvae on triticale compared to the oat and barley varieties evaluated. 

The cereal leaf beetle is a sporadic pest of small grains including oats, barley, wheat and rye. Larvae feed directly on plant tissue resulting in skeletonized leaves, leaving a frosted appearance to the field. The larvae are small globular-shaped insects that are often mistaken for slugs.
