(Association for Advancement of Entomology, 2024) Paul Pop; Nivedita Pattanaik; Kuldeep Singh Barwal; Harminder Pal Singh; Puneet Pandey; Sanjay Sondhi; Randeep Singh
In the first ever enumeration of moth diversity of Bilaspur district, Himachal Pradesh, India, located mostly in the Shivalik range, 82 species/morphospecies were reported, at least 22 of which are new records for Himachal Pradesh, and five are new records for Western Himalayas. In addition to a list of moths for the district supplemented with photographs, identification keys for similar species, larval host plants for species, and a near exhaustive dataset of distribution of the species/genera within and outside India are also provided. © 2024 Association for Advancement of Entomology. © 2024 Association for Advancement of Entomology.
Alleviation of salt stress using PGPR
(Nova Science Publishers, Inc., 2023) Palak Thakur; Damini; Kushal Thakur; Kirti Raina; Ruchika Kumari; Rohit Sharma; Randeep Singh; Amandeep Singh; Ashun Chaudhary
Nowadays, increased salt content in agricultural fields has become an acritical environmental concern, posing a threat to the human population worldwide regarding food security. Salinity can occur for several reasons, both natural and man-made. Natural soil salinization is caused by the weathering of high-salt-content rock minerals and sediments, fossil salt deposits, coastal land salinization, and salt transport in rivers. Anthropogenic activities result in salinization via improper irrigation, excessive groundwater extraction, land clearing for agriculture, the utilization of waste effluents, and excessive usage of chemical fertilizers. The freshwater supply is gradually dwindling and there is an urgent need for elucidation of the threat caused by salinity. Cultivating salt tolerance through classical breeding programmes is a much-preferred scientific purpose, but with modest success. Starting to introduce salt-tolerant microorganisms that increase crop development is another method for boosting crop salt tolerance. The salt-impacted region around the vicinity of plant roots provides a source of PGPR that can aid plants in adjusting to and growing in high-salinity conditions. Eco-friendly and plant growth is influenced by PGPR in direct and indirect ways with no detrimental effects on the environment. Direct mechanisms include phytohormone biosynthesis, siderophore, increased nitrogen fixation, and increased phosphate solubilization. Indirect mechanisms include phytopathogen inhibition, synthesis of antibiotics, siderophores, and ACC deaminase. By influencing elemental cycling as well as nutrient management, effective PGPR can help to manage salt stress, accelerate the production of crops, and diminish the use of fertilizers. © 2024 Nova Science Publishers, Inc.

Factors Affecting Immune Responses in Honey Bees: An Insight
(Sciendo, 2021) Gurleen Kaur; Rohit Sharma; Ashun Chaudhary; Randeep Singh
Honey bees pollinate various crops and wild plants which ensures food security. However, in this modern world, bees are suffering. Decreasing global domesticated and wild bee populations while the demand for agricultural pollination services is increasing is a matter of concern. Colony losses are driven by such factors or interactions as changing environmental conditions, exposure to agrochemicals, parasite and pathogens attack and decreased flower abundance and diversity. All these stresses individually or together affect the immune system of bees and consequently bee fitness. Poor nutrition is the key stressor as it directly suppresses the immune system and reduces host resistance to other stressors. To cope with these stresses, honey bees have well-developed individual and social immune systems which initiate several defence reactions, but its activation, maintenance and use are detrimental for bee survival as it occurs at the cost of bee health. This review summarizes the causal factors and their possible interaction responsible for immune suppression in honey bees. © 2021 Gurleen Kaur et al., published by Sciendo 2021.
Mechanistic role and potential of Ayurvedic herbs as anti-aging therapies
(Walter de Gruyter GmbH, 2023) Kirti Raina; Ruchika Kumari; Palak Thakur; Rohit Sharma; Randeep Singh; Abhinay Thakur; Vikas Anand; Ashun Chaudhary
Introduction: Medicinal plants and herbs are the most important part of the Ayurveda. The term Rasayana in Charaka Samhita confers long life, youthfulness, strong body, freedom from diseases and the plants mentioned in Rsayana possess antiaging property. Aging is the collective term used for the complex detrimental physiological changes that reduce the functional ability of the cell. Oxidative stress, telomeres shortening, inflammation, and mitochondrial dysfunction are the main factors that regulate the aging process. Chronological aging is an irreversible process but the factors causing biological aging can be controlled. Ayurvedic herbs are better for the management of age-related problems. There are several natural bioactive agents present in plants that can delay the aging process in humans. They trigger actions like enhancing gene longevity and telomerase activity, ROS scavenging furthermore regeneration of tissues. Content: The plants mentioned in the Rasayana of Ayurveda have antiaging potential and can be used to solve modern problems related to aging. Some Ayurvedic plants and their antiaging potential has explained in this review. The main causes of aging, medicinal plants and their use as potential antiaging mediator are covered in this study. Summary: The process of aging is still an enigma. It is a complex, irretrievable, dynamic process that involves a number of factors and is subject to a number of environmental and genetic influences. Rasayana aspect has not been much investigated in clinical trials. Aging is considered to result from free radical damage. According to Charaka, Rasayana drugs open the partially or fully blocked channels. Many Rasayanas show free radical scavenging activity and has the potential to mitigate the effects of aging. It gives an overview of the significance of Ayurvedic medicinal plants as a source of inspiration and the use of these plants as remedies for antiaging. Outlook: This study briefly outlooks the causes of aging and how medicinal plants can be used to reverse the aging process. In this study, we discussed the antiaging potential and mechanistic roles of Ayurvedic herbs. These herbs have the properties to slow down the natural process of aging and can successfully manage common age-related problems. © 2023 Walter de Gruyter GmbH, Berlin/Boston.
