| Abstract | Aqueous (physiological saline) extracts of seed kernel from seven indigenous plants were initially screened for their antimosquito activity against eggs, larvae of all instars, and pupae of Aedes aegypti. Among various seed kernels tested, the soapnut Sapindus emarginatus (Sapindaceae) extract was found to exhibit, for the first time, a strong antimosquito activity as evident from its ability to inflict 100% mortality of all the developmental stages of A. aegypti. Furthermore, the kernel extract of S. emarginatus also exerted ovicidal, larvicidal, and pupicidal activity against two other important vector mosquitoes, namely, Anopheles stephensi and Culex quinquefasciatus. Differential susceptibility of the various developmental stages of the three mosquito species exposed to soapnut extract was also noticed. The kernel extract was found to be safe for two nontarget aquatic insects tested: the larvae of Chironomus costatus and the nymphs of Diplonychus rusticus. Lethal concentration values of soapnut extract to these nontarget insects were always threefold or fivefold higher than those that produced 100% mortality of the larvae of the three mosquito species examined. The findings of this study clearly demonstrate that the aqueous kernel extract of S. emarginatus has potent antimosquito activity detectable against all the developmental stages of three important vector mosquito species as well as it is safe for nontarget aquatic organisms, and thus this new botanical resource could be used as an eco-friendly alternative biocidal agent in control of mosquitoes. |

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.
