| Abstract | Paper previously exposed for short periods to first instar larvae ofChrysopa oculata Say (Neur.: Chrysopidae) deters conspecific females from ovipositing. The deterrent effect was not reduced by keeping the substrates at temperatures of up to 140°C for one hour.The oviposition-deterring pheromone is volatile. If contaminated substrates were kept in the open air for 3–4 weeks they no longer deterred females from ovipositing. However, the deterrent effect did not decrease significantly when the substrates were kept for 20 weeks in small Petri dishes. Clean paper substrates enclosed for one day above glass previously walked over by larvae also deterred females from ovipositing.Un morceau de papier préalablement exposé pendant de courtes durées à des larves de 1° stade deChrysopa oculata Say (Neur.: Chrysopidae) empêche de pondre les femelles de la même espèce. Cet effet n’est pas réduit si on place le substrat à des températures allant jusqu’à 140 °C pendant une heure.Cette phéromone anti-oviposition est volatile. Si les substrats contaminés sont conservés en plein air pendant 3–4 semaines, ils n’empêchent plus la ponte. Cependant l’effet anti-oviposition ne diminue pas significativement au bout de 20 semaines de conservation du substrat dans des boîtes de Petri. Des substrats de papier intact placés pendant une journée au-dessus d’un morceau de verre sur lequel se sont auparavant déplacées des larves empêchent aussi les femelles de pondre. |

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.
