Technical Abstract: The Hessian fly is the major insect pest of wheat in the southeastern United States and has traditionally been controlled through the utilization of Hessian fly resistance (R) genes in wheat. Such R genes are a limited resource, and once deployed lose their field effectiveness with time. Using 21 of the named R genes, a recent evaluation determined that only 5 of the R genes tested were able to provide adequate protection for wheat. Thus, there is a need for novel genetically engineered resistance to this pest. One approach to genetically engineered resistance in wheat is the possible application of plant mediated RNAi to target Hessian fly genes essential in its biology and interactions with wheat. To identify efficacious targets for plant mediated RNAi in transgenic resistance we are utilizing the newly available Hessian fly genome sequence to annotate Hessian fly genes involved in essential metabolic and biosynthesis pathways. Here, we report on the annotation of the genes involved in some of these pathways.
