  1. Asiatic Garden Beetle Grub Sampling Methods Paper Published in Crop Protection

    Dec 13, 2022

    Tilmon Lab research on the 'Active and passive sampling methods for grubs of the Asiatic garden beetle, Maladera formosae (Coleoptera: Scarabaeidae), in a corn-soybean rotation' was recently accepted and published in the journal, Crop Protection. This research was led by former Tilmon Lab Ph.D student, Dr. Adrian Pekarcik and included co-authors Amy Raudenbush, Eric Richer and Kelley Tilmon. The article focuses on AGB grub sampling in corn fields in northwest Ohio. The paper evaluates multiple sampling methods that growers/researchers could use to monitor for AGB grubs.

  7. AGB Summit

    Mar 1, 2022

    The annual Asiatic Garden Beetle Summit was hosted virtually on Monday February 28th via Zoom. The meeting was organized by Tilmon Lab Ph.D. Candidate, Adrian Pekarcik. Adrian presented on a number of topics including AGB history, sampling methods, biology. In addition, Dr. Elizabeth Long (Purdue), presented updates on AGB in mint and Amy Raudenbush (OSU) presented results from semi-field bioassays. Lastly Joe Bruce from AMVAC Corporation joined in to explain the latest spray technology offered for growers. 

  8. Asiatic Garden Beetle Bulletin Update

    Jan 10, 2022

    The Identification, Monitoring, & Management of Asiatic Garden Beetle in Field Crops bulletin was updated for 2022 and is available to view or print on the Aginsects website. This bulletin is a collaboration between The Ohio State University and Michigan State University and is authored by Adrian Pekarcik, Kelley Tilmon and Eric Richer (OSU) and Chris DiFonzo and Bruce Mackellar (MSU). 

  9. Research Update: Asiatic garden beetle grub density research presented at ESA

    Nov 9, 2021

    Kyle Akred, Tilmon Lab MS student, presented his research at the annual Entomological Society of America conference in Denver, CO. Kyle has been evaulating how increasing Asiatic garden beetle (AGB) density impacts corn plant health, particularly plant height under both greenhouse and outdoor microplot conditions. Grub densities evaluated were 0, 1, 2 and 3. Overall, results indicated that corn plant height was negatively impacted as AGB density increased. Furthermore, 30% of corn plants with 3 grubs did not germinate compared to 4.3% in the treatment with 0 grubs.
