| Abstract | Under laboratory conditions, we investigated the host suitability of 24 poaceous plants for Trigonotylus caelestialium (Kirkaldy) and Stenotus rubrovittatus (Matsumura). More than 50 % of the nymphs of both bugs reached the adult stage on Poa annua L., Alopecurus aequalis Sobol. var. amurensis (Komar.), Poa sphondylodes Trin., Hordeum murinum L., Agrostis clavata Trin. ssp. matsumurae (Hack. ex Honda), and Lolium multiflorum Lam. In addition, a similar number of S. rubrovittatus nymphs reached the adult stage on Dactylis glomerata L. and Digitaria violascens Link. However, a high percentage of T. caelestialium adults emerged on both spikelets and leaves of the host plants, whereas a lower percentage of S. rubrovittatus adults emerged on leaves than on spikelets. While the numbers of T. caelestialium adults that emerged on spikelets and leaves were similar, those reared on spikelets had a shorter developmental period and longer forewings than those reared on leaves, indicating that spikelets were more suitable for growth. In addition, more adults of both species emerged on plants with ears that arise during the spring and early summer than on plants with ears that arise during the summer and fall. Therefore, the development of these bugs is dependent on the season of ear emergence. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
