| Abstract | The braconid parasitoid wasp that attacks exposed lepidopteran larvae, Meteorus pulchricornis (Wesmael), is a common natural enemy of pest caterpillars and may serve as a biological control agent. Recently spreading nighttime lighting for the control of noctuid moths may affect the behavior of the parasitoid if it is nocturnal, but little is known about its daily activity patterns. This study investigated the locomotor activity of M. pulchricornis under various light conditions. Over a daily 16-h light:8-h dim light cycle (16L8Dim), the wasps were inactive during most of the photophase (16L), gradually becoming active late in the photophase, with activity levels peaking just after the switch to the scotophase (8Dim). Subsequently, during the scotophase, activity decreased to a moderate level and continued at that level until the switch to the photophase. In addition, after transfer from daily light/dim light cycles (16L8Dim), daily fluctuations in activity persisted for at least 1 day under continuous light or dim light conditions. This is the first report describing the nocturnal activity rhythm of parasitoid wasps and the suppression of their activity under strong light conditions. |

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.
