Summary: This study examines the long-term neurological effects of neonicotinoids on nematodes and finds that the neonicotinoid thiacloprid impairs serotonergic and dopaminergic neuromuscular behaviors. It also shows that different neonicotinoids may have diverse effects on neural endpoints. Furthermore, the study suggests that further research into the neurochemistry of nontarget organisms is necessary for a comprehensive assessment of neurotoxicity by neonicotinoids.

Summary: Neonicotinoid mixtures are commonly found in streams worldwide, but their ecological impacts are not well understood. This study shows that exposure to neonicotinoids above certain thresholds can lead to a loss in taxa abundance and richness, disrupted adult emergence, and altered trophodynamics. The presence of neonicotinoid mixtures in California streams also poses greater than expected risks to stream health.

Summary: The research highlights the differential toxicity of neonicotinoid insecticides to freshwater insects, with imidacloprid showing higher toxicity. This implies a need for stricter regulation to control its use. Furthermore, the study suggests that neonicotinoid mixtures may deviate from additive toxicity and exhibit complex interactions.

Summary: The study found that IMI and THM significantly impacted the locomotor behavior and transcription of genes related to synaptic transmission in zebrafish, indicating neurotoxicity of these insecticides.

Summary: Adding habitat within agricultural ecosystems is important in supporting pollinators. Pesticide exposure to pollinator habitat near crop fields is necessary for risk assessments. Research found that neonicotinoids detected in milkweed leaves were at concentrations unlikely to negatively impact monarch butterfly larvae.

Summary: A study proposes an efficient method using an activated carbon/magnetite mixture adsorbent for fast removal of neonicotinoid insecticides. The adsorption capacity of the adsorbent was 192 mg g-1, and the removal of the target molecule was achieved in only 10 minutes. This research demonstrates the potential applications of the studied mixture in water cleaning technologies and analytical systems.

Summary: The European Union instigated a moratorium on neonicotinoid seed treatments in 2013, but allowed their use on non-flowering crops like winter wheat. While clothianidin detection rates remained constant over three years, thiamethoxam residues disappeared and imidacloprid detection was infrequent but persistent. The highest neonicotinoid residues were associated with honey produced by foraging on oilseed rape and wild plants, leading to a full EU ban in 2018.

Summary: The study characterized the bioremediation potential of six bacterial species on neonicotinoid insecticides, finding that maximal removal of the insecticide occurred at 30 degrees Celsius for all bacterial species assessed.

Summary: A study found multiple metabolites of neonicotinoid insecticides (NNIs) in drinking water in mainland China and Hong Kong, with urea and desnitro/decyano metabolites being the main types. Metabolite levels were significantly higher in urban areas compared to nonurban areas, with higher metabolite levels in the south possibly due to lower soil pH, higher temperatures, and greater light intensities.

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: Neonicotinoids negatively affect pollinators, leading to a decline in their population, mainly by affecting the nicotinic acetylcholine receptor and thus impacting the behavioral attributes of pollinators. Future research will further clarify the main cause behind this loss.

Summary: A dispersive micro-solid phase extraction (D-mu-SPE) method was investigated for the microextraction and preconcentration of neonicotinoid insecticide residues, followed by high-performance liquid chromatography analysis. The method showed good linearity, low limit of detection, and high enrichment factor. It was successfully used for the determination of neonicotinoid insecticide residues in different samples, with high recoveries achieved.

Summary: The study investigated the combined effects of water temperature, chemical concentration, and duration of exposure to the neonicotinoid thiacloprid on marbled crayfish. It was found that at higher temperatures, both concentrations of thiacloprid showed a synergistic effect on biochemical indicators, leading to changes and damage in blood and tissue structures.

Summary: Despite the environmental concerns, neonicotinoid insecticides remain the most widely used group of insecticides due to their reported insecticidal efficacy and potential plant bioactivation. However, the potential double benefit and interconnection with neonicotinoids have been little explored, particularly considering the whole plant phenology. This study found that neonicotinoid application on soybean seeds showed hormesis effect on certain parameters of the plants, but did not show evidence of cascading plant-mediated hormesis to the whiteflies.

Summary: This comparative study investigated the heterogeneous photocatalytic degradation of two neonicotinoids, revealing differences in transformation and mineralization influenced by various additives, matrices, and inorganic components. The role of (OH)-O-center dot and direct charge transfer in transformation was highlighted, with implications for ecotoxicity changes and the formation of hardly oxidizable intermediates. Fluorination of TiO2 had no significant impact on transformation rates but altered product distribution, enhanced dechlorination, and hindered mineralization. The negative effects of tap water and biologically treated domestic wastewater were significant, suggesting a complex interaction between matrices and radical scavenging capacity.
