Technical Abstract: Hessian fly, Mayetiola destructor (Say), is one of the major pests of wheat, which cause enormous economic loss. Several lines of evidence suggest that Hessian fly larvae inject saliva into host plants during feeding, causing severe stunting and plant death at seedling stage. To identify components injected into host plants by the Hessian fly, we adopted an EST approach to identify and characterize cDNAs and genes that encode proteins with a secretion signal peptide. BLAST nucleotide similarity searches indicated that two of the identified clones encode for protease inhibitors. Northern blot data shows that the identified clones were found to be expressed only in the larvae of the first instar which is critical for the larvae to establish infestation
