| Abstract | Effective biological control of a weed cannot be achieved unless agents can inflict sufficient damage for the plant’s growth and reproduction to be significantly depressed. The leaf-mining fly Hydrellia lagarosiphon is being considered for release in Ireland and New Zealand as a biocontrol agent for the invasive African macrophyte Lagarosiphon major. However no leaf-mining biological control agent has achieved successful control of any submerged macrophyte to date. Pre-release efficacy experiments help predict the likelihood of the biocontrol agents impact provided trials take into account expected agent densities and field conditions. Sustained damage induced by consecutive generations of the leaf-mining fly was capable of halting plant growth and undamaged shoot fragments produced 100 % more shoot biomass in just 70 days when compared with those exposed to larval damage. The number of larvae required to induce this level of damage was less than the maximum number of larvae a plant can sustain under both laboratory and natural field conditions and was between three and four larvae per shoot tip. Larval damage to L. major also had a significant effect on the subsequent establishment of detached apical shoots under field conditions. All control shoots displayed 100 % establishment whereas medium (three larvae per shoot) and high larval density plants (five larvae per shoot) had 85 and 25 % establishment, respectively. Pre-release trials indicate that relatively low larval abundances of H. lagarosiphon can contribute to the suppression of plant growth and reduce the establishment of shoot fragments, making this species a potentially effective biocontrol agent. |

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.
