| Abstract | The density and survival of leafminers were examined on 50 sun leaves from each of 65 Quercus dentata Thunb. individuals in northern Japan in 1997 and 1998. Phyllonorycter (two species), Caloptilia (one species) and Stigmella (three species) were abundant or common on this oak in the study area. These leafminers appeared after mid-June, whereas most externally feeding caterpillars occurred from late May to early June when the water content and nitrogen concentration of leaves were high. The density of these leafminers was about four times higher in 1998 than in 1997. A negative correlation was more often observed between mine density and leaf size, leaf wet weight per area or leaf toughness in the Phyllonorycter species, but the opposite correlation was more frequent for Caloptilia and Stigmella species. Conversely, no clear relation was observed between the survival of Phyllonorycter larvae and leaf traits. In all leafminers except the gregarious Stigmella species, the mine density was more often positively correlated with leaf damage by chewing insects, and also the survival of Phyllonorycter larvae was often positively correlated with leaf damage. In the Phyllonorycter species, the survival of larvae tended to increase with the increase in density at the autumn generation. The correlation in the densities of mines between the summer and autumn generations was more frequently positive in the Phyllonorycter and Caloptilia species. In addition, the densities of different leafminers were often positively correlated. Thus, relations among leafminers, between leafminers and externally feeding caterpillars, and also between herbivores and host plants are complicated. |

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.
