| Abstract | Silkworms (Bombyx mori L.) accumulate 1-deoxynojirimycin (DNJ), a mulberry iminosugar, by feeding on mulberry leaves. DNJ is a potent α-glucosidase inhibitor that helps prevent diabetes. However, iminosugars are toxic to many insects. In this study, we analyzed the concentrations of three major mulberry iminosugars—DNJ, 2-O-α-d-galactopyranosyl-DNJ (GAL-DNJ), and fagomine—in the larvae of mulberry-feeding insect species (two mulberry specialists and six non-specialists), to clarify the differences in accumulation, metabolism, and excretion of iminosugars between specialists and non-specialists. DNJ and fagomine concentrations in the two Bombyx larvae were much higher than those in the other larvae. GAL-DNJ concentrations were low in all species. DNJ and fagomine concentrations in the excrements of Agrotis segetum (Denis and Schiffermüller) and Sarcopolia illoba (Butler) larvae were lower than in those of the other larvae. Further, iminosugar concentrations in the hemolymph of B. mori, B. mandarina Moore, and S. illoba larvae were analyzed. DNJ and fagomine concentrations in the hemolymph of the two Bombyx larvae were much higher than in that of S. illoba. DNJ concentrations in the whole bodies of the two Bombyx larvae decreased as they developed. Similarly, DNJ, and fagomine concentrations in the hemolymph of B. mori larvae decreased with growth. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
