Lessons Learned from the 2019 Nebraska Floods: Implications for Emergency Management, Mass Care, and Food Security.

This qualitative study aimed to understand the actions, challenges, and lessons learned for addressing the food and water needs of flood survivors, with a special focus on vulnerable populations and the implications for food security, to inform future disaster response efforts in the U.S. Semi-structured in-depth interviews were conducted from January to August 2020 with the local, state, and national stakeholders ( = 27) involved in the disaster response to the 2019 Nebraska floods, particularly those involved in providing mass care, such as food, water, and shelter, for the flood survivors.

Restoration of susceptibility following removal of selection for Cry34/35Ab1 resistance documents fitness costs in resistant population of western corn rootworm, Diabrotica virgifera virgifera.

Background: Management of the corn pest, western corn rootworm (WCR), Diabrotica virgifera virgifera (LeConte) (Coleoptera: Chrysomelidae), relies heavily on the planting of transgenic corn expressing toxins produced by the bacterium Bacillus thuringiensis (Bt). This has resulted in the evolution of resistance to all of the four commercially available Bt toxins targeting coleopteran insects. In this study, we evaluated the susceptibility of a Cry34/35Ab1-resistant WCR colony in seedling and diet toxicity assays after removal from selection for six and nine generations.
