| Abstract | In coastal forests of Cameroon, colonies of the ant Aphomomyrmex afer are found in hollowed twigs of two species of trees, most commonly the myrmecophyte Leonardoxa africana T3. Established colonies of this ant are always associated with coccoid homopterans (the pseudococcid Paraputo anomala or the coccid Houardia abdita, or both) within hollow twigs, and ants appear to be dependent on these sap-sucking trophobionts. We dissected domatia of juvenile host-plants that had not yet acquired an established colony to determine (1) how colonies are founded, and (2) when and how trophobionts are acquired. Colony foundation is claustral. A single queen chews an entrance hole into an unoccupied domatium that serves as the founding chamber. The entrance hole is partially closed by debris and later by callus growth. Nineteen foundresses were located while still in the claustral phase, with no workers or a few nanitic workers. Of the 19 foundresses, 12 had at least a single Paraputo anomala individual in the same domatium. One of the queens had two female P. anomala nymphs attached to her body. The remaining 7 foundresses were not associated with coccoids.¶These results indicate that mealybug and ant may co-disperse by phoresis of juvenile female mealybugs on founding queens. Association with mealybugs should provide foundresses with a food source during claustral foundation. The coccid Houardia does not seem to co-disperse with ants, and foundresses originating from adult colonies that tend only coccids must acquire trophobionts later. |

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.
