| Abstract | The present work aimed to determine the impact of nucleopolyhedrovirus (NPV) on the development of Eocanthecona furcellata Wolff and to measure the infectivity of NPV discharged through its faeces. Developmental time, survival rate, sex ratio and incubation period of the predator reared on different proportions of healthy and NPV infected S. litura larvae as lifetime meal did not vary significantly. However, when the proportion of infected prey in the predator’s lifetime meal exceeded 50 % significant reductions in body weight, fecundity, longevity and percent egg hatchability were noticed. The virus did not show detrimental effect on the developmental biology of the predator in the subsequent generations when offspring emerging from nymphs fed only on virus infected prey throughout their life were reared on 50 % of infected prey. Therefore, adverse effects on E. furcellata are unlikely in the field as the predator is not expected to consume more than 50 % of infected prey even if the virus application is done at recommended dose. Under field conditions, it was found that increased proportions of infected prey enhanced the dissemination of viral inoculum through the faeces of the predators and the subsequent infection in S. litura larvae ranged from 22 to 52 %. |

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.
