Abstract

Cowpea pod borer Maruca vitrata (F.) is serious pest of cowpea (Vigna unguiculata (L.) Walp) in field as it feeds on various parts of the plant. Present study is to identify new sources of resistance against this pest in cowpea accessions. 46 culitivars including wild accessions were field screened. Ten accessions (CGCFS-8, CGCFS-15, CGCFS-30, CGCFS-48, CGCFS-49, CGCFS-52, CGCFS-65, CGCFS-67, CGCFS-69, UPC-5286,) were observed to be highly resistant (0 to 20% damage); and nine accessions (CGCFS-2, CGCFS-43, CGCFS-51, CGCFS-68, CGCFS-75, CGCFS-116, CGCFS-118, CGCFS-103, CGCFS-109, CGCFS-114) were moderately resistant (21- 40% damage).
