| Abstract | Bird cherry-oat aphid, Rhopalosiphum padi (L.), is one of the most serious pests of cereals, with an almost worldwide distribution. A primary screening test was carried out to gauge the resistance or susceptibility of 40 wheat lines to R. padi, and follow-up experiments were conducted to determine the development and fecundity rates of R. padi on eight lines. The forty wheat lines examined were classified into two major classes and four subclasses: A (e.g., ERWYT 87-1) and B (e.g., ERWYT 87-20, ERWYT 87-11), with the highest average number of aphids 14 days after infestation, subclass C (e.g., ERWYT 88-8, ERWYT 87-6, ERWYT 87-4), with the lowest average number of aphids, and subclass D (e.g., ERWYT 88-12, ERWYT 88-13), with intermediate status. Aphid nymph developmental time and survival both differed among the wheat lines. Differences were also observed in the fecundity of R. padi, the intrinsic rate of increase (r $_{m}$), and other parameters among the wheat lines tested. The highest and lowest values of r $_{m}$ were obtained for ERWYT 87-1 and ERWYT 88-8 (0.36 and 0.26 nymphs/female/day, respectively). Three lines (ERWYT 87-4, ERWYT 87-6, ERWYT 88-8) were relatively resistant to R. padi, which could prove useful in the development of IPM programs for this aphid in wheat fields. |

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.
