... In this work, a highly sensitive immunochromatographic test strip (ITS) based on Scandium-Tetrakis (4-carboxyphenyl) porphyrin (TCPP) metal–organic framework nanocubes (ScTMNs) was developed for ultrasensitive and facile visual determination of imidacloprid (IDP). TCPP as the porphyrin-based planar ligand and Sc³⁺ as the metal center were applied to form the ScTMNs via coordination chelation. Givi ...

Abstract:
... Multiple pesticides are heavily applied in crops grown in China's tropics due to the prevalence of diseases and pests, thus posing potential risks to nontarget organisms (e.g., honeybees, lacewings, ladybugs, and humans). However, there is little information on this topic. This study is the first assessment of the occurrence, driving factors, and ecological/human health risks of 32 current-use pes ...
... The use of pesticides is one of the causes that contribute to the decline of bumblebees worldwide. Some effects of neonicotinoids are known on bumblebees from temperate climates; however, there are no studies carried out with species from tropical climates, in which there could be different effects since they have different ecological traits. We demonstrated that in a neo-tropical bumblebee, B. ep ...

Abstract:
... The most widely used assays for pesticides currently rely on the inhibition of natural enzymes, which are particularly sensitive to the surrounding environment, leading to some unreliable results. Up till now, there are few studies explored chemical detection methods for these stable pesticides. Here, we reported a novel chemosensor system and polymer materials for highly sensitive detection of im ...

Abstract:
... Ten different IPM modules were evaluated against mustard aphid, Lipaphis erysimi (Kalt.). The treatment schedule comprising two sprays of imidacloprid 17.8 SL (0.005%) caused maximum reduction of aphid population with the cumulative mean of 77.29 and 79.11% after 3 days of spray, during 1st and 2nd years, respectively. It was followed by the treatment thiamethoxam 25 WG @ 0.005%. The maximum seed ...

Abstract:
... Biochar has been widely used in advanced oxidation processes (AOPs) for the decomposition of organic contaminants. However, the role of intrinsic metals in hyperaccumulator biomass in the physico-chemical properties and performance of peroxodisulfate (PDS) activation by biochar is still unclear. This work employed hyperaccumulator biomass containing Fe, Mn and Zn, respectively. Result showed that ...

Abstract:
... BACKGROUND: The red imported fire ant, Solenopsis invicta Buren, is a significant urban, agricultural, and medical pest with a wide distribution in the world. Surface or mound treatment using contact insecticide is one of the main methods to control S. invicta. In the present study, cycloxaprid, a newly discovered neonicotinoid insecticide, was evaluated for S. invicta control and compared with tw ...

Abstract:
... Blattella germanica (L.) (Blattodea: Blattellidae) is one of the major household pests worldwide, commonly named German cockroach. Application of gel baits is one of the most efficient management methods. This study investigated the effect of 3 commercially available Imidacloprid gel baits on the palatability of dead cockroaches and, consequently, on the efficacy of secondary killing. German cockr ...

Abstract:
... A novel luminescent UiO-66-NH₂ (UN) demonstrated great potentials to sense imidacloprid (IM) and thiamethoxam (TH) pesticides with high sensitivity and desirable selectivity. The UN exhibits superb luminescence emission properties, which have been found to enhance the aggregation-induced emission (AIE) of IM and TH. The enhanced AIE of IM and TH on UN has been applied for the sensitive sensing of ...

Abstract:
... Neonicotinoids have been detected in many species of wild birds; however, few studies have quantified population-level exposure. We examined population-level exposure to 7 neonicotinoids in 2 species that use agricultural areas, sharp-tailed grouse (Tympanuchus phasianellus) and greater prairie-chickens (T. cupido). We sampled fecal pellets at leks in spring and collected livers from hunter-harves ...

Abstract:
... Honey bee Apis mellifera L. colonies produce two distinct phenotypes of workers during summer and winter to cope with drastic seasonal variations in climate and food resources. Imidacloprid (IMP) is a neonicotinoid insecticide widely used in agriculture for pest management control. In this study, we investigate the influence of seasonal phenotype and emerging conditions on the diet behavior of bee ...

Abstract:
... The levels of pesticides reaching the biological wastewater treatment plants have been increasing. Operational conditions leading to the most efficient removal of pesticides in these plants should be evaluated first before attempting tertiary-level treatment options. This study investigated the influence of solids retention times (SRTs) on the removal of three pesticides (carbendazim, imidacloprid ...

Abstract:
... Recently, the high toxicity of neonicotinoids to the survival and reproduction of adult earthworms has become apparent in standard 56‐day toxicity tests. The persistence of some neonicotinoids and/or their repeated application may lead to long‐term exposure, possibly also affecting other parts of the life cycle of earthworms. The present study aimed at providing insight into the sublethal effects ...
