| Abstract | A search for means of biologically controlling the red palm weevil (RPW) Rhynchophorus ferrugineus resulted in the isolation of several microbial cultures belonging to bacteria, actinomycetes and fungi. Among the obtained cultures, three potent spore-forming bacilli were further isolated from natural habitats associated with insect-damaged date palms in Egypt. The isolated bacterial cultures, (strains 73, 15 and 27) were identified as variants of Bacillus sphaericus, B. megaterium and B. laterosporus, respectively. Under standard bioassay conditions, the mortalities of the second-instar larvae of the target insect induced by the three isolated bacilli variants ranged between 40 and 60%. The most active culture (strain no. 73) was identified as B. sphaericus. This isolate formed spherical endospores and crystalline endotoxin comparable to those of B. sphaericus standard strain 2362, which is pathogenic to mosquito larvae, as shown by electron microscopy. However, the amino acid composition of the spore-endotoxin complexes was markedly different. |

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.
