| Abstract | Nests of Syneuodynerus egregius, Euodynerus posticus, Ancistrocerus antilope, and A. nigricornis have a similar structure and consist of a linear row of cells separated by transverse partitions made of soil mastic. The number of cells in the nests is 1–11 (5.6 ± 0.8) in S. egregius, 1–7 (2.6 ± 0.2) in E. posticus, 1–10 (4.0 ± 0.7) in A. antilope, and 1–28 (7.9 ± 1.3) in A. nigricornis. Most nests consist of several cells in S. egregius and A. nigricornis and of one or two cells in E. posticus and A. antilope. The female to male ratio is 1.2: 1.0 in E. egregius, 1.5: 1.0 in E. posticus, 1.9: 1.0 in A. antilope, and 1.0: 1.0 in A. nigricornis. The nests of S. egregius usually contain brood of both sexes; those of A. antilope, that of one sex. The sex ratio is correlated with the diameter of the occupied nest cavities only in A. antilope. The volume of the cells with females exceeds that of the cells with males in all the species studied: by 23, 34, 54, and 98% in S. egregius, E. posticus, A. antilope, and A. nigricornis, respectively. The relative difference between the body masses of male and female prepupae is correlated with the relative difference between the volumes of their cells. The nest cells of S. egregius are separated by double partitions consisting of homologs of cell bottoms and lids. In the nests of E. posticus the partitions are single; each cell has a bottom and a lid, with “false cells” being located between them. In the nests of A. antilope and A. nigricornis, the partitions are single but all of them are homologs of the cell bottoms. The nest cells of S. egregius belong to the equilinear type; their length is relatively constant in the cavities of various diameters. The nest cells of A. antilope are of the equivolumetric type: their length is smaller in broad cavities and greater in narrow ones, the cell volume being relatively constant in the cavities of different diameters. The nest cells of E. posticus and A. nigricornis are of the intermediate type. Statistical models of nests reflecting their mean parameters and composition were built. The evolutionarily primitive and progressive features in the nest structure are discussed. |

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.
