| Abstract | Flight dimorphism has been considered to result from a balance of costs and benefits between flight capability and reproduction. The validity of the hypothesis, however, has been challenged recently. In this study, we examined the effect of flight time on trade-off between flight capability and reproductive development in Velarifictorus aspersus and we found that flight of 5 min did not promote reproductive development of long-winged (LW) adults, but flight of 30, 60, or 120 min could promote reproductive development both in female and male crickets. The results indicate that flight time may serve as a signal for LW V. aspersus to switch from migration to reproduction, and trade-off between flight ability and reproduction may be attenuated when flight time reaches a critical threshold. In addition, rapid reproductive development occurred before dealation when LW insects were allowed to fly for 30 min, which indicates that flight may influence reproductive development directly. Food consumption of short-winged adults was significantly higher than that of unflown LW adults or LW adults with 5 min flight, but similar to that of LW adults with 30, 60, or 120 min flight, suggesting that difference of reproductive development may be positively correlated with their food consumption. |

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.
