Summary: The use of the pesticide imidacloprid in agriculture has been associated with declines in bee populations. This study investigated the effects of oral exposure to imidacloprid on the midgut and fat body of Apis mellifera worker larvae. The results showed that imidacloprid exposure led to changes in the midgut epithelium and disruption of the glycocalyx layer. Additionally, the fat body cells exhibited changes in lipid droplet size and protein content. These findings suggest that imidacloprid negatively impacts non-target organs during the larval development of A. mellifera.

Summary: Understanding the cumulative risk of chemical mixtures at environmentally realistic concentrations is crucial in honey bee ecotoxicology. Ecotoxicogenomics, specifically transcriptomics, can provide insights into the mechanisms underlying phenotypic responses and link them to population impacts. In this study, gene expression profiles of honey bee larvae exposed to the pesticide imidacloprid and acaricide thymol, both separately and in combination, were analyzed using RNA-seq. The separate and combined treatments had distinct gene expression profiles, affecting different signaling and metabolic pathways. The molecular signature of the mixture revealed additive interactions in stress responses and non-additive interactions in secondary responses. Novel impacts on eye development genes correlated with long-term defects in visual learning performance. Establishing mechanistic links between molecular and phenotypic responses is important when predicting the effects of chemical mixtures on populations.

Summary: This study investigated the effects of imidacloprid (IMD) on honey bees. The results showed that field-realistic doses of IMD negatively affected honey bee energy metabolism in different ways at low and high concentrations. At low concentrations, IMD caused a decrease in body weight, flight capability, and energy metabolism, similar to insulin resistance and diabetic symptoms. At high concentrations, IMD led to an increase in body weight and a decrease in energy metabolism.

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: Pollination services by honey bees are critical in ecosystems, but increased death rates in bee colonies in recent years stem from complex stressors. Studying specific cellular processes and stress responses impacted by multiple stresses is crucial in understanding these interactions.

Summary: In this study, the homing ability of honey bees was investigated from the perspective of energy supply. The results showed that imbalance in energy supply caused by pesticides can lead to a reduction in wingbeat frequency and impair the flight ability of worker bees.

Summary: Agricultural intensification and pesticide use have negative effects on the homing ability of pollinators, with the new pesticide sulfoxaflor having higher toxicity. Homing ability tests can be used to assess the impact of these pesticides on bee health and provide valuable data for predicting colony health effects.

Summary: Honey bees are important pollinators and model organisms for studying social behavior, development, and cognition. Researchers have engineered a bee gut bacterium, Snodgrassella alvi, to induce a sustained host RNA interference response that reduces the expression of targeted genes. This method offers a streamlined and scalable approach for studying honey bee biology.

Summary: A challenge in bee protection is to assess the risks of pesticide-pathogen interactions. This study found that both Lotmaria passim parasite and imidacloprid pesticide may affect the physiology, behavior, immunity, microbiome, and lifespan of honey bees. Cage experiments showed that imidacloprid increased the infection rate and load of L. passim in individual bees. Proteomic analysis revealed that imidacloprid neutralized the effect of L. passim on transferrin 1 expression.

Summary: Honey bees are commonly used for pesticide risk assessments, but this approach may underestimate risk to non-target species. A study found that a solitary ground-nesting bee, L. paahaumaa, was more sensitive to imidacloprid compared to honey bees, highlighting the need for more comparative toxicity studies.

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 impact of Chlorella supplementation on the health and physiology of honey bees. The results showed that Chlorella significantly improved food consumption, longevity, gland development, muscle formation, and gene expression compared to pollen or sugar diet alone. The best outcome was observed with 2% Chlorella supplementation to the pollen diet.

Summary: Strength auditing of European honey bee colonies is critical for colony health management. This study evaluates the use of temperature sensing technology in colony strength assessment and identifies key parameters linking temperature to colony strength. The presence of bees in hives significantly affects hive temperature and range, and sensor placement across the width of the hive is important when linking sensor data with colony strength. Statistical models can be used to predict colony strength from temperature sensor data.

Summary: The arboreal marsupial monito del monte is a key species in the temperate rainforest, as it acts as the main seed disperser for endemic plants. It is also one of the few hibernating mammals in South America, able to reduce energy expenditure during winter. Despite low reproductive rates, this marsupial shows high densities due to its unique habitat. However, immediate actions are needed to protect the species from habitat destruction and climate change.

Summary: Heat stress affects the fertility of dairy cattle, but supplementing vitamins E and coenzyme Q10 can alleviate its adverse effects on oocyte maturation and embryo development. Vitamin E was found to be more effective than vitamin C and coenzyme Q10 in improving maturation and cleavage rates, as well as increasing the count of blastocyst cells.
