| Abstract | We have investigated efficacy of a diatomaceous earth (DE) and an aerosol formulation thereof for contact and residual effects against the common bed bug, Cimex lectularius L. Efficacy of commercially available DE dust samples varied with the product. DX13TM and MotherEarth® dusts were significantly more effective than other DE dusts based on their lower lethal doses to kill 50 % of the insects, LD 50 values (LD 50s = 0.17 and 0.18 g m−2, respectively), in contact bioassays with adult bugs. DX13TM-aerosol demonstrated residual effect in both plastic box and the Petri dish methods. In large plastic boxes mortality of the bed bugs due to residual effect of the aerosol was 98 % at 24 h. The residual effect of DX13™-aerosol in Petri dishes persisted for 21 days. Time to kill 50 % of the insects, LT 50 value, increased from 10.2 h for freshly applied DE dust to 46.1 h for dust aged for 21 days in Petri dishes. Mortality of the bed bugs in the Petri dishes was >97 % at 72 h, not only for fresh DX13™-aerosol residue, but also for residues aged up to 14 days. Mortality was 81 % at 72 h for DX13™-aerosol residue aged for 21 days. Mortality of bed bugs confined on a DX13™-incorporated mattress was 100 % at 48 and 72 h for bugs introduced on the mattress 3 and 32 weeks after manufacture, respectively. We also observed horizontal transfer of DX13™-dust between dead bugs collected from the DX13™-incorporated mattress to untreated ones. We discuss potential use of DX13™ for the management of bed bugs. |

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.
