| Abstract | Material brought to midden piles of leaf-cutting ants is considered to be hazardous. It is therefore expected that midden workers should not re-enter the colony, to reduce pathogen transmission. Here, we examined whether the midden workers of Atta sexdens rubropilosa remain confined to the waste compartment and, if not, whether they could perform many different behaviors in the absence of specialized nestmates. Eleven subcolonies received either midden workers or non-midden workers in addition to pupae and 50 mL of fungus garden. Survival, fungal and brood care, foraging and waste manipulation were observed daily until subcolonies death. Subcolonies maintained by midden workers died earlier: average survival times were 13.92 and 22.66 days for midden and non-midden workers, respectively. Midden workers cared for the brood and foraged as non-midden workers did but they were not as efficient in caring for the garden. Activities related to waste manipulation were more frequently performed by midden workers. These results show that midden workers are not a behaviorally rigid caste and retain many labor capabilities being able to leave the waste compartment and perform internal activities in the absence of specialized internal workers. |

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.
