Over the last few decades, increasing human population, infrastructure development, and land-based economic development in many tropical countries in Asia have significantly reduced the area and quality of forests. Lim et al. (2017) and Chen et al. (2023) reported that forest conversion into plantations and infrastructure development are the main triggers of forest degradation and deforestation in Southeast Asia.

Vaccination has made an enormous contribution to global health. Treatment resistance for infectious diseases is growing quickly, and chemotherapeutic toxicity in cancer means that vaccines must be made right away to save humanity. But subunit vaccinations alone don’t give enough strong and long-lasting protection against infections that can kill. Nanoparticle (NP)-based delivery vehicles, such as dendrimers, liposomes, micelles, virosomes, nanogels, and microemulsions, offer interesting ways to get around the problems with traditional vaccine adjuvants. The nanovaccines (50–250 nm in size) are most efficient in terms of tissue targeting, staying in the bloodstream for a long time. Nanovaccines can improve antigen presentation, targeted delivery, stimulation of the body’s innate immune system, and a strong T-cell response without putting people at risk. This can help fight infectious diseases and cancers. Also, nanovaccines can be very helpful for making cancer treatments that use immunotherapy. So, this review highlights the various types of NPs used in the techniques that have worked in the new paradigm in viral vaccinology for infectious diseases. It gives a full rundown of the current NP-based vaccines, their potential as adjuvants, and the ways they can be delivered to cells. In the future, the best nanovaccines will try to be more logically designed, have more antigens in them, be fully functionalized, and be given to the right people.

Northeast India has various water bodies including the tributaries of the Brahmaputra and Barak river systems, wetlands, lakesand beels. These water bodies support the diversity of many fish species. Seasonal changes in the number of fish species inthe SIS category were also observed and they are most abundant during the winter and least abundant during the monsoonseason. Many researchers collected fish data from Assam's rivers and wetlands, particularly small indigenous species (SIS).Small Indigenous Species (SIS) of fish are a vital and conveniently accessible source of rare protein, vitamins, and minerals intraditional diets. The present study aimed to review Assam's small indigenous fish species and their nutritional worth. Thesources of the review article were Google Scholar, Web of Science, ScienceDirect, and PubMed for SIS nutrition composition,fish nutritional profile, and fish proximate composition. Northeast India’s rural inhabitants get their sustenance from fish SIS. TheSIS of Northeast India fish species contain proteins, lipids, vitamins, minerals, and vital macro- and micronutrients. The proteincontent of SIS range from 12.49% to 18.30% (12.49–18.30g/100 g), lipid content from 0.7% to 19.63% (0.7–19.63g/100 g),moisture content from 65.88% to 82.8% (65.88–82.8g/100 g), and ash level from 2% to 6.8% (2–6.8g/100 g). This review suggests SIS has adequate nutritional benefits because it is an excellent source of proteins, lipids, vitamins, minerals, and omega-3 fatty acids necessary for optimal health. Northeast India’s impoverished region might achieve their nutritional demands by eating more SIS of fish.

The effects of the application of aqueous extracts of a selection of five traditional plants (Murraya paniculata, Cassia tora, Amphineuron opulentum, Tithonia diversifolia, andCassia alata) were compared with that of synthetic acaricide in reducing the population of red spider mite (Oligonychus coffeae), a major tea pest, alongside their impact on natural enemies and green leaf yield. Analysis of large-scale field trials showed that all the five plants extract treatments resulted in similar yield; this was analogous to the application of synthetic acaricide. A reduction in the pest population was observed to be on par with the synthetic acaricide, with a higher number of natural enemies treated using the pesticide-plant-treated plot in comparison to the synthetic acaricide-treated plot, which indicated pesticidal plants had a lower impact on natural enemies. A phytotoxicity study on tea leaves indicated that aqueous extracts of selected plants are non-phytotoxic and do not impart any taint to the prepared tea samples. Therefore, the present investigation outlines how plant extracts used as a botanical pesticide display toxicity against red spider mite on tea plants without harming the beneficial insects, increasing the yield and avoiding any lethal consequence for the tea plants or consumers.

COVID-19 is possibly the greatest and most enormously significant crisis against humans in the planet's modern history. The group of Coronaviridae includes viruses with very long RNA genomes of up to 33,500 nucleotides. SARS-CoV-2 belongs to the Sarbecovirus family, with an approximate genome size of 30.000 nucleotides (Wu et al., 2020). SARS-CoV-2 has four main structural proteins: spike (S), envelope (E), membrane (M), and nucleocapsid (N). Additionally, some other non-structural proteins are encoded in the pp1a and pp1ab polyproteins, essential for viral replication (Wu et al., 2020; Baruah et al., 2020; Baruah et al., 2021; Sharma and Baruah, 2021). The coronavirus has upended our way of life, but it's also having a dramatic impact on animals across the globe too, from black rhinos being poached in Botswana to a coughing tiger in New York and emboldened goats on the streets of Wales.

Abstract Background Entomopathogens are pathogenic to insect pests. Several types of naturally occurring, viz. fungus, bacteria, viruses, and nematodes, infect a range of insect pests and help manage crop growth. They offer several advantages over chemical pesticides, including being precise, safe, and ecologically sustainable. Agricultural systems are streamlined, and changes to natural ecosystems occur. Viruses, bacteria are host-specific, while fungi have a greater host range, and they may infect both soil-dwelling and aboveground pests. Main body The study highlights the current state of knowledge on entomopathogenic microorganisms (EM) (entomopathogenic fungi, nematodes, viruses, bacteria, etc.) as it relates to their current usage as biological pest management. It is essential to enhance our understanding of the ecology of EM and their role in nature to use a variety of biological control techniques against insect hosts. This article may help to comprehend their accomplishments in the significant field. Some recent researches indicated common patterns in interactions between insect pests and EM. Conclusion More focus has been placed on the use of natural enemies like entomopathogens for pest control in recent years. EM expands possibilities for insect control. Eco-friendly alternatives to existing agricultural pesticides are being developed which are utilized to control insect pests and support agricultural sustainability.

Background: Tea is a natural beverage made from the tender leaves of the tea plant (Camellia sinensis Kuntze). Being of a perennial and monoculture nature in terms of its cultivation system, it provides a stable micro-climate for various insect pests, which cause substantial loss of crop. With the escalating cost of insect pest management and increasing concern about the adverse effects of the pesticide residues in manufactured tea, there is an urgent need to explore other avenues for pest management strategies.Aim: Integrated pest management (IPM) in tea invites an multidisciplinary approach owing to the high pest diversity in the perennial tea plantation system. In this review, we have highlighted current developments of nanotechnology for crop protection and the prospects of nanoparticles (NPs) in plant protection, emphasizing the control of different major pests of tea plantations.Methods: A literature search was performed using the ScienceDirect, Web of Science, Pubmed, and Google Scholar search engines with the following terms: nanotechnology, nanopesticides, tea, and insect pest. An article search concentrated on developments after 1988.Results: We have described the impact of various pests in tea production and innovative approaches on the use of various biosynthesized and syntheric nanopesticides against specific insect pest targets. Simultaneously, we have provided support for NP-based technology and their different categories that are currently employed for the management of pests in different agro-ecosystems. Besides the broad categories of active ingredients (AI) of synthetic insecticides, pheromones and natural resource-based molecules have pesticidal activity and can also be used with NPs as a carriers as alternatives to traditional pest control agents. Finally, the merits and demerits of incorporating NP-based nanopesticides are also illustrated.Conclusions: Nanopesticides for plant protection is an emerging research field, and it offers new methods to design active ingredients amid nanoscale dimensions. Nanopesticide-based formulations have a potential and bright future for the development of more effective and safer pesticide/biopesticides.

Hyposidra talaca is a vicious pest of tea plants in the Eastern Himalayan’s Darjeeling foothills and NE India. The infestation of this pest leads to crop loss, as early instars prefer to feed the young harvestable leaves and late instars feed the matured leaves, which leads to loss of photosynthetic capacity of the entire tea bush. Among the few accessible methods to control H. talaca is the baculovirus H. talaca nucleopolyhedrovirus (HytaNPV). DNA-binding protein (DBP) plays a significant role in HytaNPV during viral replication and transcription. The present study attempted to predict the structure and the functional analysis of two crucial DNA-binding proteins (DBP-1 and DBP-2) in the absence of experimental structures. Analysis of sequence, prediction of structure, functional characterization, and evolutionary analysis based on UniProtKB studied the amino acid sequences of DBP-1 and DBP-2 proteins. Modeling of these two proteins was presented using ab-initio modeling. QMEANDisCo 4.0.0 global and local per-residue quality estimates verified the structure as high quality. Phylogenetic analysis of both HytaNPV DBP-1 and DBP-2 proteins revealed a close evolutionary relationship with Buzura suppressaria nucleopolyhedrovirus. Tunnel analysis revealed multiple tunnels in DBP-1 (six) and DBP-2 (eleven), indicating a large number of transport pathways for small ligands that influence their reactivity. The theoretical structures and statistical verifications were successfully deposited in the Model Archive. They will be useful for advanced computational analysis of each protein’s interactions for detailed functional analysis and understanding of viral pathogenesis in the absence of a complete experimental structure.

Abstract The red spider mite, Oligonychus coffeae Nietner (Acari: Tetranychidae), is a prevalent mite pest damages tea crops. The present study evaluated the efficacy of L. alba essential oil against O. coffeae. GC and GC-MS analysis of L. alba essential oil revealed geraniol (52.19%) and neral (34.13%) as major compounds. The L. alba essential oil applied at 1500 ppm exhibited 100% mortality of treated mites 48 h after exposure through fumigant toxicity method, while 99% ovicidal activity of essential oil was achieved at 1000 ppm. Similarly, in fumigant bioassay LC50 value against O. coffeae was 87.75 ppm for geraniol and 103.49 ppm for neral at 72 h after exposure. The findings suggest that L. alba essential oil and its major constituents geraniol and neral could be used as eco-friendly acaricide, and can be incorporated as one of the components in IPM after multi-location field trials.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a single-stranded RNA genome that encodes 14 open reading frames (ORFs), eight of which encode accessory proteins that allow the virus to infect the host and promote virulence. The genome expresses around 29 structural and nonstructural protein products. The accessory proteins of SARS-CoV-2 are not essential for virus replication but do affect viral release, stability, and pathogenesis and finally contribute to virulence. This paper has attempted the structure prediction and functional analysis of two such accessory proteins, 9b and ORF14, in the absence of experimental structures. Sequence analysis, structure prediction, functional characterization, and evolutionary analysis based on the UniProtKB reviewed the amino acid sequences of SARS-CoV-2 9b (P0DTD2) and ORF14 (P0DTD3) proteins. Modeling has been presented with the introduction of hybrid comparative and ab initio modeling. QMEANDisCo 4.0.0 and ProQ3 for global and local (per residue) quality estimates verified the structures as high quality, which may be attributed to structure-based drug design targets. Tunnel analysis revealed the presence of 1-2 highly active tunneling sites, perhaps which will able to provide certain inputs for advanced structure-based drug design or to formulate potential vaccines in the absence of a complete experimental structure. The evolutionary analysis of both proteins of human SARS-CoV-2 indicates close relatedness to the bat coronavirus. The whole-genome phylogeny indicates that only the new bat coronavirus followed by pangolin coronaviruses has a close evolutionary relationship with the novel SARS-CoV-2.
