There is a new, excellent publication from the Alabama Cooperative Extension Service related to the management of Hessian fly in wheat. This publication was developed in cooperation with several other southeastern states.

Biology and Management of Hessian Fly in the Southeast

The link above will take you to a page where you can download this publication for free.   There are hyperlinks embedded in this document that will direct you to additional information related to managing Hessian flies.  I’ve also posted this publication on UTcrops.com (link here).
