Research Project: Evaluating Potential Cross-Resistance between Bacterial Proteins for Western Corn Rootworm and Baseline Toxicity Assays for Northern Corn Rootworm

Location: Plant Genetics Research

Project Number: 5070-21000-041-20-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Apr 9, 2020
End Date: Apr 8, 2021

1. Evaluate baseline susceptibility of the northern corn rootworm to Cry3Bb1 in diet toxicity assays.

Diet toxicity assays will be conducted using increasing doses of Cry3Bb1 for the northern corn rootworm using an in-house ARS diet for northern corn rootworm in order to evaluate susceptibility of northern corn rootworm to Cry3Bb1. These studies will be performed using ARS’ “Brookings” non-diapausing colony, as well as wild northern corn rootworm insects.
