| Abstract | Cannibalism occurred frequently in a laboratory population ofEpisyrphus balteatus. The third instar larva was the most voracious cannibal and are mainly eggs. Pupae were never eaten. Egg cannibalism was inversely dependent on aphid density, but even occurred when prey was present in excess. Syrphid larvae can complete their development on conspecific eggs.Dans les conditions de laboratoire, on observe du cannibalisme chezEpisyrphus balteatus. Les larves de troisième stade sont les plus voraces et consomment surtout des œufs. Les pupes ne sont par contre jamais dévorées. Le cannibalisme des œufs est inversement proportionnel à la densité de pucerons disponibles. Toutefois, il se produit même lorsque les pucerons sont très abondants. Selon les résultats expérimentaux, les œufs de syrphes constituent une nourriture propice au développement des larves cannibales.Les syrphes aphidiphages pondent leurs oeufs isolément ou en petits groupes à proximité immédiate des colonies de pucerons. Ce comportement réduit probablement l’incidence du cannibalisme en conditions naturelles. |

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.
