Summary: This study investigates the impact of neonicotinoid insecticides on the thermal tolerance of honey bees. Surprisingly, exposure to sublethal doses of these insecticides enhances the heat tolerance and survival rates of bees. This suggests that honey bees have the ability to compensate for elevated temperatures when other stressors are present.

Summary: This study investigated the prenatal exposure to neonicotinoid insecticides (NEOs) in pregnant women in China and assessed its association with birth outcomes. The study found that exposure to NEOs may have an impact on the head circumference and ponderal index of newborns, and this association may be mediated by urinary 8-OHdG. These findings are important for understanding the effects of NEOs on human health.

Summary: Neonicotinoids are widely used insecticides due to their effectiveness and low toxicity. However, their potential adverse effects on non-target species, especially pollinators, and their presence in the environment has raised concerns. Despite increasing research, our understanding of the toxicity and risks remains limited.

Summary: The study investigated the concentrations of neonicotinoids in wild boars from hunting areas in north-eastern Poland and assessed the risk to consumers. The findings showed a high presence of neonicotinoids in samples, but the chronic and acute risk to consumers was very low.

Summary: This study analyzed NEOs and their metabolites in paired urine and blood samples collected from young adults in China. The results showed widespread detection of NEOs and their metabolites in both urine and blood samples, with gender-related differences in concentrations. Urinary levels were found to be good predictors of human exposure to NEOs and their metabolites.

Summary: Neonicotinoids are widely used insecticides that have raised concerns over their impact on non-target ecosystems, specifically surface waters. A meta-analysis of 173 peer-reviewed studies found a lack of exposure information in over 90% of agricultural areas globally. The study revealed low acute risks but significant chronic risks, especially for multispecies endpoints.

Summary: This study examines the association between exposure to neonicotinoid insecticides (NEOs) and liver disease. The results show that NEOs are frequently detected in the blood samples of individuals, with higher concentrations found in females. Additionally, the concentrations of NEOs and their metabolites are positively correlated with the prevalence of liver cancer. These findings suggest that exposure to NEOs may increase the odds of developing liver cancer.

Summary: The study found that Varroa destructor and neonicotinoid insecticides may interact synergistically to negatively affect the survival of adult drones, but have antagonistic effects on emergence mass. While the impact of Varroa destructor and combined exposure on sperm quality remains unclear, neonicotinoids were observed to have no influence on sperm concentration or viability. This highlights the diverse effects of concurrent exposure to stressors on honey bees and suggests that Varroa destructor and neonicotinoids can severely affect the number of sexually mature adult drones available for mating.

Summary: This study investigated the exposure of infants in South China to neonicotinoid insecticides (NEOs). The results showed that infants had detectable levels of NEOs in urine and blood samples, breast milk, infant formula, and tap water. The concentrations of specific NEOs varied in different samples, with dinotefuran and imidacloprid being the most abundant in urine, blood, breast milk, infant formula, and tap water. Older infants had higher NEO exposure than younger infants. Blood samples had higher concentrations of NEOs compared to urine samples, indicating that NEOs readily enter the bloodstream. Breast-fed infants had higher exposure levels than formula-fed infants. The study also found that external sources contributed to the majority of NEO exposure in infants.

Summary: This study evaluated the temporal variability of neonicotinoid biomarkers in urine samples over one year in Chinese young adults, and found that most neonicotinoid biomarkers had poor reproducibility in spot urine samples. At least 2-4 spot urine samples are recommended for assessing one-year neonicotinoid exposure.

Summary: This study found that sublethal, field-realistic concentration of the neonicotinoid imidacloprid has a significant impact on the foraging and recruitment behaviors of honey bees. Honey bees treated with imidacloprid showed decreased foraging frequency and duration, potentially affecting their food intake and colony health.

Summary: A nitrogen-rich urchin-shaped covalent organic framework (U-COF) was synthesized and used as an adsorbent to remove neonicotinoid insecticides (NEOs). The U-COF exhibited good adsorption capacities for imidacloprid, acetamiprid, and thiamethoxam. The nitrogen-rich structure and abundant π electron system of U-COF improved the adsorption capacity for NEOs.

Summary: This study found that urinary concentrations of neonicotinoid insecticides (NNIs) were associated with an increased risk of gestational diabetes mellitus (GDM). Oxidative DNA damage, RNA damage, and lipid peroxidation mediated these associations. Maternal age and pre-pregnancy BMI modified the association between NNIs and GDM.

Summary: This study measured the concentrations of nine major neonicotinoid insecticides and ten main metabolites in urine samples from pregnant women. The results showed widespread exposure to these compounds in the human body, with concentrations decreasing throughout the trimesters. The study also found that maternal age, educational level, and household income were associated with the concentrations of these compounds.

Summary: By analyzing honeybee samples from China, this study detected 21 pesticide residues, with pyrethroid pesticides having the highest detection frequency. Compared to Apis cerana cerana, Apis mellifera ligustica showed higher acute toxicity to four pyrethroid pesticides, and had a higher survival rate when exposed to the same concentration of beta-cypermethrin.
