| Abstract | The way in which species coexist is an important ecological question. Often, several parasitoid species may share a common host species. Five species of Ooencyrtus Ashmead (Hymenoptera: Encyrtidae) co-inhabit the egg clusters of Stenozygum coloratum Klug (Hemiptera: Pentatomidae), in the East Mediterranean region. Their relative abundance and spatial and seasonal occurrence were investigated. Parasitism and parasitoid male ratios gradually increased to about 50 and 26.8 %, respectively, from May to October. O. telenomicida Vassiliev was dominant in Mediterranean climatic regions and absent from arid areas, O. fecundus Ferrière and Voegelè dominated semi-arid areas, and O. near nigerrimus was the commonest in hot-arid areas. O. near fecundus occurred everywhere but was most abundant in the more extreme weather conditions. O. pityocampae Mercet was uncommon in most areas and absent from arid ones. O. telenomicida abundance was positively, and that of O. fecundus negatively, correlated with annual rainfall. O. near fecundus and O. near nigerrimus abundance was positively correlated with temperature extremes. The results display a clear picture for climatic based spatial niche partitioning, although there is evidence that interspecific competition also plays a significant role in the frequency of occurrence of the studied Ooencyrtus spp. |

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.
