| Abstract | The small size and cryptic nature of thrips pests often make their monitoring and the identification process difficult. With the aim to obtain accurate identification of various pest species in the order Thysanoptera, a pilot study was conducted on an invasive thrips species Scirtothrips dorsalis Hood in Florida. The specific objective of this pilot study was to assess if the thrips specimens processed to be observed under scanning electron microscopy (SEM) can be further utilized for DNA based assays. Larvae and adults of S. dorsalis were subjected to traditional morphological identification using high resolution SEM prior to their DNA extraction. Sequence results of both mtCO1 and ITS rDNA of individual larva and adult S. dorsalis were found to be in agreement with the taxonomic identification conducted using SEM and each result confirmed the other technique. Our results suggest that steps involved during specimen preparation and observation under SEM does not impact DNA analysis of the sample. The two techniques together could be used for the correct identification of various thrips species using the same specimen. The proof of concept was further tested on three other important thrips species Frankliniella occidentalis (Pergande), F. schultzei (Trybom) and Thrips palmi Karny, which confirmed the robustness of the technique. The technique has broader significance for different areas under entomological sciences especially medical, forensic and taxonomic studies where the samples put under a high beam of ions for investigation are often required for DNA analysis. |

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.
