| Abstract | The seeds of high-yielding and earlier-maturing cowpea cultivars, IT83E-761, TVNu-72, TVx3236 and Ife Brown were compared for their pods resistance to Callosobruchus maculates, a cosmopolitan field-to-store pest and principal post-harvest pest of cowpeas. Parameters used for comparison were mean number of eggs laid on each cultivar, mean percent egg hatched, mean percent larval mortalities, mean percent pupal mortalities, mean percent emerging adult mortalities, mean percent adult emergence, developmental periods and percent weight loss of seed. TVNu-72, Tvu 3236 and TVu 3000 demonstrated significant resistance to C. maculates compared to IT83E-716 and Ife brown with pods showing more resistance than seeds. These cultivars caused both larval mortalities and significant deterrence to oviposition. In comparison, C. maculates showed significant preference for Ife brown and IT83E-716 compared to others as significantly more eggs were laid on the former than the latter (cultivars). It is suggested that pod wall hairiness and thickness, seed coat oviposition deterrent factor(s) and cotyledonal antibiotic factor(s) are involved in conferring polygenic resistance on TVNu-72 and Tvx 3236 cultivars. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
