| Abstract | Social parasitism, including temporary paratisism, slave-making, and inquilinism, is one of the most intriguing phenomena in ant societies. Inquiline ants are workerless, completely rely on the worker force of their host ants, and have evolved numerous traits to exploit the host’s resources and to increase their own fitness. We examined the inquiline ant Vollenhovia nipponica, which is a social parasite of the congeneric species Vollenhovia emeryi. Host nests collected in the field usually contained multiple V. nipponica queens, suggesting that it is polygynous. However, the average number of queens in a nest decreased from spring to summer, and many old queens were found dead after the eclosion of new sexuals in late summer. Vollenhovia nipponica therefore appears to have a short life span as found in other inquiline ants. Laboratory observation revealed that inseminated queens were aggressive towards each other. Queen-queen antagonism led to the formation of dominance hierarchies, in which only a few dominant queens developed their ovaries and laid eggs. Subordinate queens frequently left the nests by themselves. The system is very similar to “functional monogyny”. |

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.
