| Abstract | Eretmocerus sudanensis = E. nr. emirates was released in 1992 into South Florida from Sudan to control Bemisia tabaci. It has since become the dominant Eretmocerus species in southwest Florida. Specimens were recovered at the Southwest Florida Research and Education Center in Collier County from a population of B. tabaci on collard Brassica oleracea, and the parasitoid described as new species, though as yet unpublished. Here we report results of studies conducted to evaluate the biology of this parasitoid of B. tabaci biotype B under laboratory controlled conditions (26°C ± 0.5, 13 h light, 62% ± 6 HR). No preoviposition period was observed for E. sudanensis. Females lived an average of 13.2 days and in this time deposited an average of 161 eggs at a mean oviposition rate of 13 eggs per day. The total compared favorably with published values for E. melanoscutus (123 eggs) and was similar to E. mundus (171 eggs). E. sudanensis showed the same tendencies of preference and suitability for the intermediate host stages (2nd and 3rd) as reported for these same 2 species. However, parameters such as development time from egg to adult (16 days) and net reproductive rate (Ro = 91.3 eggs/female) were shorter and greater, respectively, compared to published results for either E. melanoscutus or E. mundus under similar conditions. Such differences in demographic parameters could indicate a significantly greater reproductive potential for E. sudanensis. |

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.
