Hessian Fly-Infested Susceptible Wheat Seedling

Caption

A Hessian fly-infested susceptible wheat seedling before (top) and after (bottom) staining with red dye. The larvae induce the host plant cells to increase in permeability, as visualized by their ability to absorb the red stain. This increased permeability allows plant nutrients to leak to the surface where they are consumed by the larvae.
