| Abstract | Background Global climate change significantly impacts ecosystems, particularly through temperature fluctuations that affect insect physiology and behavior. As poikilotherms, insect pests such as the globally devastating diamondback moth (DBM), Plutella xylostella, are especially vulnerable to rising temperatures and extreme heat events, necessitating effective adaptive mechanisms. Results Here we demonstrate the roles of zinc finger proteins (ZFPs) in mediating thermal adaptability in DBM. We utilized a comprehensive approach involving cloning and bioinformatics analysis of three ZFPs, PxZNF568, PxZNF93, and PxZNF266, measurement of their expression levels in hot-evolved and control strains, and assessment of catalase enzymatic activity and total antioxidant capacity. We also employed CRISPR/Cas9 technology to create five stable homozygous knockout strains to elucidate ZFP functions in high-temperature tolerance. Survival rates under high-temperature stress and the critical thermal maxima (CTMax) of the knockout strains were significantly lower than the wild-type strain, and exhibited marked decreases in antioxidant capacity. Conclusion Findings reveal the importance of ZFPs in thermal adaptability of DBM, contributing critical insights for future pest management strategies in the context of a warming climate and laying the foundation for further exploration of ZFP functionality in agricultural pest control. |

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.
