Project Number: 6202-22000-028-11
Project Type: Trust

Start Date: Jun 15, 2009
End Date: Sep 30, 2013

Objective:
Determine the susceptibility/tolerance/resistance of Heliothis virescens and Helicoverpa zea to Bt toxins.

Approach:
Local crops grown by agricultural producers and experimental plantings of susceptible crops/hosts made by ARS will be monitored for occurrence of larvae. When available in sufficient numbers for bioassays, larvae will be collected during the growing season, placed in plastic cups containing diet, and shipped via overnight express to the locations where bioassays are being conducted.
