Tolerance as a potential method for hessian fly control

It has long been known that reducing selection pressure on insect pests will help to reduce the evolution of virulence within pest populations.  One potential method of controlling a pest without increasing selection pressures is to exploit the use of tolerance in a plant line.  In this work, we have used two related Pioneer brand wheat lines, 25R75 (susceptible to Hessian fly) and 25R78 (tolerant to Hessian fly) as well as Newton (unrelated control) to look at the effects of Hessian fly infestation on the wheat growth and yield and on Hessian fly development.
