    Acaricidal and Ovicidal Effects of Vitex negundo, Against Oligonychus coffeae, A Common Pest Found in Tea Gardens of North Bengal, India
    (University of North Bengal, 2023) Ghosh, Sandipan; Sen, Gargi; Ghosh, Chandra; Sen, Arnab
    Tea, a widely consumed and economical beverage across 65 nations, confronts substantial challenges from pests, notably the destructive Red spider mites, which pose significant hurdles for the industry due to their resilient nature and severe impact. Chemical pesticides, while effective against pests in tea production, degrade tea quality, prompting exploration into natural alternatives like floral diversity for pest control. A study in North Bengal, India, aims to the pest-controlling abilities of common weed found in tea gardens in the Terai and Dooars regions.The aqueous extracts of Vitex negundo L. as biocide employed in this study demonstrated substantial acaricidal and oviposition deterrent action against the tea Red Spider Mite Oligonychus coffeae after 48 hours of application. In the future, this aqueous extract could prove to be a fairly priced and efficient acaricide.

    Underutilized Fruits of Northeast India and its Potential Benefits on Human Health - Review
    (University of North Bengal, 2023) Banerjee, Swarnendra; Sen, Arnab
    The Indian Himalayas, a global biodiversity hotspot, is home to 2532 species from temperate regions of Europe, China, Burma, the Sahara, and Africa. India's plant biodiversity includes 21 agroecosystems, including farmed fruit and wild, under-utilized fruit crops. These underutilized fruit crops have potential but are rarely planted, infrequently available on the market, or not farmed commercially. They are disease-resistant and adapted to heat and cold extremes, blessing tropical nations like India. Underutilized fruit crops have medicinal properties and are often used by Native Americans to heal ailments and for the financial well-being of tribal people in rural regions. The use of wild fruits as nutritional supplements or less expensive alternatives to commercial fruits is growing worldwide. Identifying and utilizing underutilized species is crucial for a diverse and nutritious diet, especially for rural poor and socially vulnerable populations in emerging countries. India's North-Eastern Hill region is an agrobiodiversity hub characterized by diverse ethnic and cultural backgrounds. It is rich in wild agricultural plant relatives, particularly underutilized fruit crops, and mixed temperate, tropical, and subtropical fruits from various genera. Fruits, vegetables, and other plants naturally produce important polyphenol metabolites that influence their sensory and nutritive qualities, potentially curing various conditions.

    PhytoResp : A Database for Medicinal Plants of Darjeeling, Against Respiratory Ailments
    (University of North Bengal, 2022) Das, Anushka; Banik, Ananya; Datta, Sutapa; Sen, Arnab
    PhytoResp is a digital, manually curated database developed at the Department of Botany, University of North Bengal (NBU). The database has been created with the help of 200 published research articles and the eleven volumes of ‘Chiranjib Banousadhi’ series, written by Shibakali Bhattacharya. Here, we provide the names of 329 medicinal plants that are available in the Darjeeling district region of North Bengal and are traditionally used in the treatment of respiratory diseases. The list of reported plants is included, along with their parts used. They are known to cure 38 respiratory diseases. Among these, 113 plants have already been reported as a cure for COVID-19 (in silico or in vivo). Also, we have taken a step to evaluate the efficiency of the phytocompounds through in-silico methods.

    Persepectives on Extremophilic Actinobacteria - A Review
    (University of North Bengal, 2022) Sen, Gargi; Ghosh, Sandipan; Sarkar, Indrani; Sen, Arnab
    Actinobacteria are considered as the most potential and biotechnologically viable prokaryotes because of their ability for the production of bioactive metabolites. They have immense biosynthetic prospect that remains unopposed without a competent organism from other microbial collections. But the prospect of finding highly potential actinobacteria from ambient habitats is reduced due to the wide exploitation for antibiotic production. So attention has been diverted to the unexploited extremophilic habitats such as marine sediments, mangroves, deserts, rocks, glaciers, etc. Extremophilic actinobacteria are competent producers of new secondary metabolites that show a wide range of antagonistic activities against bacteria, fungi, cancer and also exhibit insecticidal and enzyme inhibition. This review is an attempt to explore extremophilic actinobacteria that may form the source for the synthesis of novel drugs that could be used to combat resistant pathogens and also for xenobiotic degradation.
