| Abstract | The parasitoid Encarsialahorensis has been present in Israel since its import in 1980 for biological control of Dialeurodes citri, a serious pest of citrus. The larvae of D. citri secrete honey dew, which is colonized by sooty mould fungi, leading to aesthetic impairment of the fruit as well as leaf drop and yield loss. In a process which took about 3years, the parasitoid reduced the pest to low levels and maintained the population beneath the economic damage threshold for several years. This study, carried out in a citrus orchard during the years1987–1991, was intended to demonstrate the existence of efficient biological control by comparing the pest populations before and after the unhindered introduction of the natural enemy to a new region. In the course of two years, the pest population decreased from a peak level of 122 eggs to 2–7 per half-leaf. Concurrently, the population of the vulnerable fourth nymphal in star decreased from a maximum of 12 to 3 perhalf-leaf. Thereafter, D. citri was maintained at this low level, with peaks of parasitism ranging from20 to 50%. It was concluded that D. citri is under successful biological control in Israel by the specific parasitoid E. lahorensis. |

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.
