Indian meal moth, Plodia interpunctella (Lepidoptera: Pyralidae), is a serious pest of stored products. We assessed the efficacy of combined application of Beauveria bassiana AAD16 and azadirachtin against P. interpunctella under laboratory conditions by using filter paper dipping method. P. interpunctella larvae showed lowest LT50 in combined application of AAD16 and azadirachtin compared to the application of only azadirachtin. The mycosis rate of P. interpunctella larvae was 100% after 14 days of the combined application while AAD16 only application showed 93%. These findings suggest that B. bassiana AAD16 and azadirachtin combined solution can be an effective controlling technique against P. interpunctella larvae.

Major pests of greenhouse strawberry include Tetranychus kanzawai (Acari: Tetranychidae) and Bemisia tabaci (Hemiptera: Aleyrodidae) causing significant damage in both yield and quality. We compared control efficacy of two entomopathogenic fungus strains of Beauveria bassiana, AAD16 and GHA, against T. kanzawai and B. tabaci. Both fungus were applied as a foliar spray targeting the undersides of leaves. In preliminary studies in the laboratory, adult T. kanzawai and B. tabaci showed lower LT50 values when treated with AAD16 strain compared to GHA. In the greenhouse, the densities of the both mites (adult and nymph) and whiteflies (adult) were significantly reduced with the application of the two fungus strains compared to the control. The mycosis rate was 88-94% in T. kanzawai and 48-59% in B. tabaci on collected leaves. These findings suggest that Beauveria bassiana AAD16 can be an effective mycoinsecticide against both T. kanzawai and B. tabaci.

Bangladeshi medicinal plants (BMP) have a history of traditional use in treating chronic inflammatory diseases, but a BMP bark’s antioxidant and anti-inflammatory effects remain largely unexplored. This study assessed methanolic extracts’ antioxidant and anti-inflammatory properties from the bark of 15 medicinal plant species native to Bangladesh. The methanol extracts of BMP bark were evaluated for their total antioxidant activity and ability to counteract inflammation induced by lipopolysaccharide (LPS) in RAW 264.7 macrophages. Among the 15 bark extracts from BMP, Albizia odoratissima (A. odoratissima), Engelhardia spicata (E. spicata), and Shorea robusta (S. robusta) showed the highest total phenolic contents and total antioxidant capacity by effectively scavenging free radicals. In particular, these three bark extracts significantly reduced the mRNA expression of LPS-induced inflammatory cytokines and enzymes inducible by inflammation in macrophages. Also, the mRNA expression of NADPH oxidase 2 was significantly suppressed by the three bark extracts in LPS-induced RAW 264.7 macrophages. These results suggest that out of the 15 bark extracts obtained from medicinal plants in Bangladesh, the extracts from A. odoratissima, E. spicata, and S. robusta exhibit substantial total antioxidant capacity by efficiently scavenging free radicals and also inhibit LPS-induced inflammation in macrophages.

Background: Reproductive management practices play crucial roles to maximize the reproductive performance of cows, and thus contribute to farm profitability. We aimed to assess the reproductive management of cows currently practiced in the dairy farms in an urban farming system. Methods: A total of 62 dairy farms were randomly selected considering all size of farms such as small (1-5 cattle), medium (6-20 cattle) and large farms (> 20 cattle) from selected areas of Dhaka city in Bangladesh. The reproductive managementrelated parameters viz. estrus detection, breeding method, pregnancy diagnosis, dry cow and parturition management, vaccination and treatment of reproductive problems etc. were obtained in a pre-defined questionnaire during the farm visit. Results: The visual observation method was only used (100.0%; 62/62) for estrus detection irrespective of size of the farms; while farmers observed cows for estrus 4-5 times a day, but only for 20-60 seconds each time. Regardless of farm size, 89.0% (55/62) farms used artificial insemination (AI) for breeding the cows. Intriguingly, all farms (100.0%) routinely checked the cows for pregnancy at 35-40 days post-breeding using rectal palpation technique by registered veterinarian. However, only 6.5% (4/62) farms practiced dry cow management. Notably, all farms (100.0%) provided nutritional supplements (Vit D, Ca and P) during late gestation. However, proper hygiene and cleanliness during parturition was not practiced in 77.4% (48/62) farms; even though 96.7% (60/62) farms treated cows by registered veterinarian for parturition-related problems. Conclusions: While farmers used AI service for breeding and timely check their cows for pregnancy; however, they need to increase observation time (30 minutes/ observation, twice in a day: early morning and early night) for estrus detection, consider dry cow management and ensure hygienic parturition for maximizing production.

Since Russia-Ukraine war, India and the United States has enhanced their cooperation as evidenced by the recent engagements. Multiple meetings by officials and leaders including two Quad and 2+2 dialogue summits, have provided a clear stance on each country’s perspective on the recent conflict. The US-India dispute regarding Russia-Ukraine war demonstrates that it is a stress test for the US-India ties, as well as a test of the US leadership in the global politics. The balancing act required to settle the differences between the two countries will have implications for the Indo-Pacific region as well as global security, even though the disagreements are not yet mutually incompatible. Strengthening ties with the US is now a tightrope walk for India. While there are differences between the two countries in Ukraine, the real challenge is turning these differences into opportunities. The paper deals with the different issues arising from the Russia and Ukraine conflict in the context of US-India interface.

Soybean aphid, Aphis glycines Matsumura has been identified as a pest of soybean in Korea, Japan, and China. The use of synthetic chemical insecticides is a major option to manage this pest, but the demand for environmental-friendly insecticide is increasing. Entomopathogenic fungus is one of the alternatives which is safe for the environment. In this bioassay, leaf dipping method was used to evaluate Beauveria bassiana (Balsamo) Vuillemin ARP14 and GHA. The mortality of both adults and nymphs was not significantly different between the two fungus strains. However, faster mortality rate in both life stages of aphid was found in ARP14 compared to GHA strain. Also, the mycosis rates of both adults and nymphs were higher in ARP14 than in GHA strain. Our results suggest that B. bassiana ARP14 can be an effective and an environmental-friendly control agent for A. glycines.

Tetranychus kanzawai Kishida (Acari: Tetranychidae) is a major pest on strawberry, reducing both the quality and quantity of fruit production. We compared the virulence of an entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin ARP14 with a commercial GHA strain against T. kanzawai. In the laboratory, leaf dipping method was conducted while a one-time spray was carried out on selected planting units in strawberry greenhouse with each fungus strain and Triton X-100 as control. Adult T. kanzawai showed lower LT50 when treated with ARP14 strain compared to GHA in the laboratory. The densities of both adult and nymph mites in the greenhouse were significantly reduced in the treatment of two fungus strains compared to the control. The mycosis rate of T. kanzawai in greenhouse was 97.9% at 14 days when treated with ARP14 strain while it was 85.5% when treated with GHA strain. The results suggest that B. bassiana ARP14 can be an effective mycoinsecticide against T. kanzawai.

The choice of suitable companion plants is crucial for enhancing pest management strategies in agricultural fields. Riptortus pedestris, an important agricultural pest, has drawn attention for its serious damage on soybean. To identify an ideal companion plant for soybean, we investigated the pest’s behavioral patterns when exposed to corn seedlings in laboratory. Series of choice experiments were conducted for 4th instar nymphs and unmated female adults of R. pedestris when presented with corn and/or soybean pot against soybean or blank pot. In 4th instar nymphs, 56% preferred the treatment of corn pot plus soybean pot over soybean alone pot while 69% of unmated female adults preferred the same combination. These findings provide valuable insights into the behavior of this insect pest, which could be beneficial for establishing polycultures in agricultural fields.

The ladybird beetles have been used as biological control agents against several pest species. The aim of this study is to evaluate the compatibility between ladybird beetles and an entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin AAD16. The virulence of AAD16 strain was compared with that of commercial GHA strain on three developmental stages of two coccinellids; Harmonia axyridis Pallas and Chilocorus stigma Say. The topical application method was used for both adult and larval stage while dipping method was used for egg stage. The LT50 and mycosis rate for all life stages of two ladybird beetles tested were not significant between AAD16 and GHA strain. In larval stage, the mycosis rates of H. axyridis and C. stigma were 36 and 40% and 63 and 60% in AAD16 and GHA strain. In adult stage, the mycosis rates of H. axyridis (male and female) and C. stigma (unsexed) were 20, 23, and 23% and 26, 30, and 30% in AAD16 and GHA strain, respectively. Therefore, the two predatory coccinellids could be compatible with these two fungus strains due to their relatively lower mycosis rate.

In recent years, various steps have been taken to build strong and effective intra-BRICS economic cooperation. Brazil, Russia, India, China, and South Africa have been meeting since 2009 and gained a lot of weightages on different areas of economic relevance. In this course, the contribution of India is very significant. The paper therefore aims to elucidate the bilateral relations of India with its BRICS counterparts. The study begins by stressing the importance of BRICS as a group and its importance in the context of India. The authors hold a descriptive methodology by adopting secondary data from various sources. The paper gives an overview of the individual bilateral relationship of India in terms of trade. Further, the study suggested how a change of policy and infrastructural development can make the relationship of India with BRICS counterparts much stronger and sustainable.

Green consumption behavior (GCB) is desirable for a better world. The trend of GCB is expected to rise in the coming years. As such, it is imperative to understand the enablers of GCB. A significant majority of the investigated drivers of GCB are consumer-level factors. Studies focusing on the consumer-level showed that factors such as values, intentions, and personal norms could influence GCB. However, it is argued that compared to values or intentions, self-determined motivation can better predict GCB. The effect of self-determined motivation types (i.e., autonomous and controlled motivation) on GCB remains unclear due to prevailing gaps and contradictory findings. Furthermore, it is posited that people exhibit more self-determined behavior if they have strong self-awareness. Higher self-awareness can be achieved through mindfulness; therefore, differences in mindfulness level could affect the motivation-behavior relationship.

The application of mindfulness is increasing significantly in different areas of business studies. However, identifying how mindfulness research has evolved and the major research themes, specifically within the business studies domain, remains lacking. This study unveils the intellectual structure of mindfulness research in business studies. Using citation and co-citation analysis, the study identifies the most influential articles, annual growth, and three key research clusters constituting the intellectual foundation.

While companies and brands have always collected and used customer data for multiple purposes, the advent of smart devices, Internet of Things (IoT), and big data has made it much easier to access and utilize consumers’ personal information. For consumers, however, such ease of access to their personal data and frequent cases of data breach have increased their concerns about data privacy (Harris & Associates, 1996; Milne et al., 2004). Nevertheless, consumers continue to share their personal information with companies and brands in the digital environment (Turow et al., 2015).

Here, upon acute (96 h) and chronic (14 days) exposure, ingestion of polystyrene NPs (100 nm) and physiological, biochemical, and cholinergic modulations were analyzed in the water flea Moina macrocopa exposed to different concentrations (0.001, 0.01, 0.1, 1, 5, 10, 50, 100, and 500 μg l-1). Exposed NPs were observed in the internal organs (e.g., digestive tract and foregut) of the water flea. Chronic exposure to the relatively high concentrations resulted in significant decreases in survival, body length, and the total number of molts, whereas reproduction parameter was not affected. Significant increase in oxidative stress biomarker (malondialdehyde) and decrease in the intracellular content of endogenous antioxidant (glutathione) and enzymatic activity of antioxidant enzymes (glutathione peroxidase, glutathione reductase, catalase, superoxide dismutase, and glutathione S-transferase) were detected in response to relatively high concentrations of NPs. Transcriptional expression of the hsp70 gene was increased in response to relatively high concentrations of NPs, whereas acetylcholinesterase activity was lowered by the same concentrations of NPs. Taken together, NPs exposure would be a significant modulator on physiological and biochemical metabolism of water flea.

In today’s world, carbon-based materials research is much wider wherein, it requires a lot of processing techniques to manufacture or synthesize. Moreover, the processing methods through which the carbon-based materials are derived from synthetic sources are of high cost. Processing of such hierarchical porous carbon materials (PCMs) was slightly complex and only very few methods render carbon nano-materials (CNMs) with high specific surface area. Once it is processed, which paves a path to versatile applications. CNMs derived from biological sources are widespread and their application spectrum is also very wide. This review focuses on biomass-derived CNMs from various plant sources for its versatile applications. The major thrust areas of energy storage include batteries, super-capacitors, and fuel cells which are described in this article. Meanwhile, the challenges faced during the processing of biomass-derived CNMs and their future prospects are also discussed comprehensively.

Рrecipitation of platinum group metals (Rh, Ru, Pd, so-called MPG) from the melt essentially affects the reliability of installations for vitrification of high-level liquid radioactive waste (HLW). To date, it is difficult to find an approach which allows simultaneous recovery of all three metals. The aim of our work was to select a sorbent that would provide simultaneous up to complete recovery of given metals. The following inorganic materials were tested as sorbents – yellow blood salt (YBS).and hexacyanoferrates of iron, aluminum, copper and nickel. The degree of metal recovery was studied is influenced by the temperature and concentration of nitric acid. Only palladium was completely recovered using YBS. At the same time, specially prepared iron hexacyanoferrate (HCF-Fe) under optimal experimental conditions recovers almost all Pd and more than 95% and 90% of Rh and Ru, respectively. The behavior of fission products, including the main dose-forming components of HLW (Cs, Sr) and Mo, U, Ag, REE) in the course of MPG recovery was studied. The experiments were carried using both multicomponent model solutions and real raffinates. Options for further management of the recovered metals have been worked out. Thus, the proposed method of metal recovery seems promising for the development of a technology for the removal of MPG from nitric HLW during the reprocessing of the spent nuclear fuel (SNF) before vitrification. The recovered metals can be probably used in various technological processes. Also, this method can provide the MPG recovery from low-concentration tail solutions.
