Summary: The anti-insecticidal potential of daidzein on Spodoptera litura larvae was investigated. Results showed that the treatment with daidzein resulted in high larval mortality, prolonged pupal and total developmental period. Anti-nutritional and post ingestive toxicity were observed, accompanied by decrease in nutritional indices and immune function. Detoxifying enzyme activities were significantly increased, indicating oxidative stress in the insect. These findings suggest that daidzein can be considered as an alternative to conventional pesticides for controlling S. litura population.

Summary: Tobacco cutworm is a serious pest that attacks economically important crops. The study found that caffeic acid inhibits the growth of tobacco cutworm larvae and negatively affects their nutritional physiology and immune response. Therefore, caffeic acid can be used as an alternative to traditional insecticides to reduce the population of tobacco cutworm.

Summary: This study examines the antioxidant and detoxifying enzyme defense systems of the pest insect Spodoptera litura in response to infection by Metarhizium flavoviride. The results show that M. flavoviride directly affects S. litura's immune system and leads to decreased immunity. The entomopathogenic fungus may be an effective alternative to synthetic chemical tools in controlling S. litura larvae.

Summary: The Northern Dvina River may be a major source of microplastic pollution in the Arctic region, with coastal sediments acting as an intermediate link in the transport of microplastics to the White and Barents Seas. The study found that a significant amount of microplastic particles, particularly ABS and PS plastics, accumulate in the coastal sediments and are carried away by strong currents, leading to pollution of the Barents and White Seas.

Summary: Chemical pesticides, while effective, are considered unfriendly to the environment in controlling agricultural diseases and pests. Bio-control agents, such as Bacillus species, are seen as sustainable and safe alternatives. In our study, we focused on the application of Bacillus subtilis as a potential bio-control agent against the rice leaffolder pest, Cnaphalocrocis medinalis. The results showed that larvae fed with B. subtilis-amended diet had significantly reduced growth efficiency, highlighting the importance of B. subtilis in managing leaffolder disease.

Summary: Entomopathogenic nematodes (EPNs) are effective biopesticides used in insect control, but their low popularity is due to the reduced infectivity caused by periodic release of stored EPNs. This study focuses on storing EPNs for a longer period of time using encapsulating beads. The results show that Arabic gum-sodium alginate combination is a promising approach and semi-field trials proved the efficacy of storing encapsulated EPNs in mosquito larval control.

Summary: Black pepper, known as black gold, has been traded like gold in the past. The market value of black pepper is determined by its color, lustre, and density. Sun-drying is a common drying method, but it affects the shiny black color. Blanching is one technique to retain the color but requires extra time and resources. An experiment was conducted to find an alternative method to retain the black color without affecting quality, and covering the berries with a 100-gauge polythene sheet for 3 or 5 hours and subsequent drying under direct sunlight proved to be effective.

Summary: A study screened a marine-derived red alga and its active constituents for their biocontrol potential against major insect pests. The larvicidal activity of the red alga extract was tested against Aedes aegypti, and its enzyme inhibition, repellent activity, and non-target toxicity were also evaluated. The results showed that the extract had dose-dependent toxicity against the exposed larvae of Aedes aegypti, and it exhibited repellent activity for a duration of up to 210 minutes. The extract also showed minimal toxicity to non-target species at the tested dosage. Overall, this study provides valuable insights for the development of bioactive insecticides and highlights the potential of algal-based pesticides for eco-friendly pest control.
