Summary: Overusing imidacloprid (IMI) inhibits secondary metabolism and plant growth. Its impact on metabolites, rhizosphere, and plant-microbe interaction in pepper plants is not well-studied. This study investigated IMI's effects on plant signaling components, secondary metabolism, and microbial communities. The findings showed that IMI primarily affects the leaves and suppresses secondary metabolites including flavones, phenolic acids, and phytohormones. IMI exposure disrupts the balance between plants and microbes, decreasing microbial populations and inhibiting plant growth.

Summary: The study found that imidacloprid-resistant and reciprocal crosses strains had lower relative fitness and fecundity, with some differences in specific parameters, while the CR2 strain showed no fitness cost in most parameters. Demographic parameters were lower in the Imida-RS strain, while the Imida-RS and CR1 strains had shorter generation time and other indicators compared to the SS and CR2 strains. These findings could inform the development of effective control strategies for D. koenigii.

Summary: An investigation was conducted to characterize the susceptibility of 43 cotton aphid populations to imidacloprid over a 2-year period. The study found variable levels of resistance in the populations, with higher resistance associated with greater cotton production intensity. Rotating modes of action and limiting insecticide use are recommended to delay the evolution of insecticide resistance in cotton aphid populations.

Summary: Rhizosphere microbial communities, formed through the interaction between plant and soil, play important roles in plant growth and health. This study found that soil origin was the primary factor causing divergence in rhizosphere microbial community, with plant genotype playing a secondary role. There were no significant differences in the rhizosphere microbial communities of different cotton genotypes, but the relative abundance of Acidobacteria phylum was higher in G. barbadense compared to G. hirsutum.

Summary: This study investigated the efficient degradation of imidacloprid (IMI), a first-generation commercial neonicotinoid, in soil using a thermally activated persulfate (PS) process. The degradation efficiency of IMI ranged from 82% to 97% with a dosage of 10 mM, while the initial concentrations of IMI in the soil were 5-50 mg/kg. The degradation of IMI followed a pseudo-first-order kinetic model at different reaction temperatures. Inhibition effects of common inorganic anions on IMI degradation were observed, with chloride (Cl-) showing the highest inhibitory effect. Soil pH and organic matter content were also found to be important factors affecting the degradation of IMI. Additionally, the thermally activated persulfate process showed high degradation efficiencies (64-97%) for three other typical neonicotinoids, suggesting its potential use for remediating neonicotinoid-contaminated soil. Quenching experiments revealed that the major reactive species in IMI degradation were sulfate radicals (SO4 .-), superoxide radicals (O2 .-) and hydroxyl radicals ( . OH). Finally, degradation intermediates of IMI were identified, and the degradation pathways of IMI included hydroxylation, denitrification, C-N bond breakage and further oxidation.

Summary: Sublethal doses of imidacloprid have long-term destructive effects on honey bees at both individual and colony levels. The molecular effects include changes in immune response, detoxification, oxidation-reduction response, phototransduction, behavior, and somatic muscle development. Despite higher tolerance in worker larvae, molecular evidence suggests potential impacts, with gene expression changes observed in larvae, pupae, and adults. Early transcriptomic switch from nurse bees to foragers indicates possible precocious foraging activity.

Summary: Long-term continuous cotton cropping leads to a decrease in soil quality and organic carbon, which negatively impacts cotton yield. The application of organic amendments, such as cotton straw and organic manure, can improve soil fertility and increase cotton yield. This study found that the combination of cotton straw and organic manure significantly improved soil quality, stability, and sustainability of cotton yield.

Summary: The study isolated Xanthomonas campestris pv. Translucens and Aspergillus fumigatus as microbial isolates capable of degrading dimethoate and methomyl residues in water. These isolates showed fast growth and degradation rates in water spiked with pesticides, with up to 97.8% and 91.2% of dimethoate, and 95% and 87.8% of methomyl being biodegraded within 32 days. Toxicity tests on rats confirmed the absence of remaining toxicity after treatment with these microbial isolates, indicating their high potential for complete degradation of pesticide residues.

Summary: We assessed the contamination, dynamics, and health risks of several pesticides in marine samples from the Seto Inland Sea in Japan. The study found that pesticide concentrations were highest near the coastline, with cyanazine being the most frequently detected pesticide in sediments, and diazinon, simetryn, and cyanazine being detected in fish and other edible marine organisms. The results indicate that plankton, fish, and marine animals bioaccumulated pesticides.

Summary: This study reviewed the trends of fenobucarb usage in Japan between 1969 and 2020 and analyzed its ecotoxicological and health risks in river water. While the amount, residues, and potential hazards of fenobucarb have decreased significantly over the past two decades, it still poses a significant threat to aquatic life in many rivers. However, it does not represent a major risk to human health through water. Therefore, monitoring pesticide usage trends and assessing risks to aquatic organisms and human health are important.

Summary: Glyphosate, the most widely used herbicide globally and in Japan, has raised concerns for its environmental and health effects due to its abundance in surface waters. This study examined the temporal use of glyphosate-based herbicides in Japan from 1989 to 2019, as well as the concentrations of glyphosate in river water. The findings suggest that glyphosate poses moderate threats to the Japanese aquatic environment and human health, emphasizing the need for regular monitoring and reassessment.

Summary: This study aimed to investigate the patho-biochemical toxicity of repeated low oral doses of malathion, metalaxyl, and cymoxanil pesticides on male rats. The results showed that low doses of these pesticides did not cause significant symptoms or histopathological changes in treated rats, while medium and high doses led to adverse signs and symptoms of toxicity. Cymoxanil was found to be the most toxic pesticide, followed by Malathion and metalaxyl. Hepatotoxicity and nephrotoxicity were evident in rats treated with cymoxanil, while neuronal and pulmonary changes were similar across all doses of the pesticides. Overall, this study recommends examining the potential adverse effects of pesticides on animals and humans before their application in agricultural fields.
