| Abstract | First-generation adults of the rice water weevil, Lissorhoptrus oryzophilus Kuschel were collected from Yueqing (28.1°N latitude, 120.9°E longitude), Zhejiang, China, during late June and mid-July and reared on rice plants (cultivar Shanyou 63) in the laboratory (28±1 °C, 16L:8D) to examine their reproductive capacity. On plants aged 16–22 days, adults from the field and collected in mid-July could reach oviposition onset more rapidly and deposit more eggs than those collected earlier. Adults that emerged in late June and early July displayed a greater tendency to become reproductive, compared with those which emerged in mid-July. However, each of these groups of adults, either field-collected or newly emerged, deposited only 3–14 eggs within 60 days of feeding. Reproductive capacity was greatly related to plant age, with plants aged below 20 days being most favorable; on plants aged over 20 days, reproductive development could take place, but little oviposition was observed. These results indicate that the reproductive capacity of first-generation adults in Zhejiang is dependent upon the time of adult emergence and post-emergence, as well as on the age of rice plants. |

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.
