Molecular Identification of Sunn Pest some Vital Genes and Analysis Effect of Different hosts on Polygalacturonase Expression

Abstract

Sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) is a serious pest of cereals which causes severe quantitative and qualitative damage to crops. Since there is less molecular data about this important pest, Sunn pest molecular gene identification can be targets for developing new tools in pest control. This study described for the first time in the world, molecular identification of Sunn pest V-ATPase subunit E, cytochrome P450 and polygalacturonase transcripts, which might serve as possible targets for integrated pest management. Also the tissue specific relative gene expression levels of polygalacturonase was determined under different host kernels (wheat, barley, rye and triticale) feeding conditions. Result showed that host plant quality can significantly influence the Sunn pest polygalacturonase expression and wheat fed larvae had higher mRNA abundant.
