Abstract:
... The present study sought to investigate the levels of multi-pesticide residues in highly consumed edible fungi in China's western regions. A total of 354 edible fungi samples were collected from the local markets, and the concentrations of 53 pesticides in these samples were determined through high performance liquid chromatography mass spectrometer (HPLC/MS/MS). Carbendazim, acephate, procymidone ...

Abstract:
... Meta-analysis was used to compare yield protection and nematode suppression provided by two seed-applied and two soil-applied nematicides against Meloidogyne incognita and Rotylenchulus reniformis on cotton across 3 years and several trial locations in the U.S. Cotton Belt. Nematicides consisted of thiodicarb- and fluopyram-treated seed, aldicarb and fluopyram applied in furrow, and combinations o ...

Abstract:
... The reniform nematode, Rotylenchulus reniformis (Linford and Oliveira), remains a common, widespread nematode pest of cotton across the southern United States. Trials were conducted during 2017 at three non-irrigated locations: one location in Hamilton, MS, and two locations in Tchula, MS, in field settings with a history of cotton production and documented economically-damaging reniform nematode ...
... A simple, sensitive and rapid fluorometric system has been developed for the detection of aldicarb (ALD) based on inner filter effect (IFE) of gold nanoparticles (AuNPs) on fluorescence (FL) intensity of carbon quantum dots (CQDs). Addition of CQDs into AuNPs, gets them aggregated due to electrostatic interaction resulting in quenching the FL intensity of CQDs. With addition of ALD into AuNPs, an ...
... The cehA gene is the earliest reported and most widely found carbaryl hydrolase gene. CehA detoxifies carbaryl and other carbamate pesticides via de-esterification. Currently, there is no systematic research available on substrate preference or the mechanism of CehA action in different hosts. In this study, we found that CehA from different hosts is highly conserved, with more than 99% amino acid ...

Abstract:
... In many European regions, people may use pesticides, particularly carbamate and organophosphorus insecticides, to deliberately poison wildlife in response to various resource-based conflicts. Repercussions of this largely illegal practice are well-documented in macro-scavengers (vultures). In southern Spain, our environmental agents are trained to gather evidence at suspected scenes of wildlife/en ...
... Originally designed as a general alternative to acute fish toxicity testing (AFT), the fish embryo toxicity test (FET) has become subject to concerns with respect to neurotoxic substances. Whereas oxygen uptake in the fish embryo primarily occurs via diffusion across the skin, juvenile and adult fish rely on active ventilation of the gills. As a consequence, substances including, e.g., neurotoxica ...

... Acetylcholinesterase (AChE; EC 3.1.1.7) from aquatic organisms have been used to evaluate the exposure of specimens to pesticides and heavy metals at sublethal levels in environmental samples. AChE of Mytella charruana was extracted to characterize its physicochemical and kinetic properties as well as the effect of organophosphate (dichlorvos, diazinon, chlorpyrifos, methyl-parathion and temephos) ...

Abstract:
... In-furrow nematicide application is a primary method for managing Rotylenchulus reniformis (Linford and Oliveira, 1940) in cotton (Gossypium hirsutum L.). Fluopyram is a relatively new non-fumigant nematicide and field data is needed to determine its efficacy at managing R. reniformis (reniform nematode, RN) in cotton production. To investigate, two experiments, consisting of multiple small plot f ...

Abstract:
... Long Island, New York, has a mix of urban/suburban to agricultural/horticultural land use and nearly 3 million residents that rely on a sole-source aquifer for drinking water. The analysis of shallow groundwater (<40 m below land surface) collected from 54 monitoring wells across Long Island detected 53 pesticides or pesticide degradates. Maximum concentrations for individual pesticides or pestici ...
... To protect ecosystems, threshold concentrations (e.g., HC₅) for chemicals are often derived using the toxicity data obtained at fixed times. Since the toxicity (e.g., LC₅₀) usually decreases with exposure time, the threshold concentrations are expected to be time-dependent, giving rise to the uncertainty in the chemical environmental criteria. Here, using the LC₅₀ data with at least 3 different ex ...
... The last decade has seen a sharp increase in nematicide research in the agricultural industry. As a result, several new synthetic nematicides have become available to growers, and several more are expected in the near future. This new interest in nematicides is related to the growing demand for safer and more selective products, and the increasing regulatory pressure on many of the traditional nem ...
... Hydrolysis catalyzed by general esterases (GEs) is the most efficient route for hydrolyzation of pyrethroid insecticides. Organophosphate (OP) and carbamate (CB) insecticides are known to inhibit GEs in addition to acetylcholinesterase (AChE), which is their main target. We hypothesize that synergies can be induced by OPs and CBs when mixed with pyrethroids, due to their inhibition of GE-dependent ...

Abstract:
... Fluensulfone is a nematicide with a novel mode of action against plant parasitic nematodes. Here, we utilize in vitro hatching assays to investigate fluensufone's ability to inhibit Globodera pallida hatching, relative to the efficacy of other distinct classes of nematicides.Fluensulfone, abamectin, aldicarb and fluopyram inhibit G. pallida hatching from cysts more potently than from isolated eggs ...

Abstract:
... The ACC-1 family of cys-loop receptors are ligand-gated chloride channels sensitive to acetylcholine (ACh), and are only present in invertebrates. Studies of this family of inhibitory receptors has provided insight into how they bind and respond to ACh in a manner vastly different from nicotinic acetylcholine receptors and appear to be present in tissues that are relevant to anthelmintic action.

Abstract:
... ContextThe Cerrado is a Global Biodiversity Hotspot as well as Brazil’s main frontier for large-scale agriculture and livestock production, making it one of the most threatened biomes in the country. Brazil is one of the biggest consumers of pesticides in the world and allows the use of chemicals that are banned in many other countries due to their adverse health effects in a wide range of species ...
... As the merit of ratiometric assay is impregnable due to potentially interfering processes, a ratiometric method for pesticide detection was developed. By adjusting glutathione : HAuCl₄ to an appropriate ratio, dual-emission luminescent ultra-small gold nanoparticles (AuNPs) with a high emission at 800 nm and a low emission at 600 nm were synthesized. Interestingly, the sulfhydryl-containing compou ...
... There are numerous early-season pests of cotton, Gossypium hirsutum L., that are economically important, including tobacco thrips, Frankliniella fusca (Hinds), and reniform nematode, Rotylenchulus reniformis (Linford & Oliveira). Both of these species have the potential to reduce plant growth and delay crop maturity, ultimately resulting in reduced yields. A field study was conducted during 2015 a ...
... Apple snails are one of the most survived fresh water invasive species that causes massive economic loss to vegetations, especially to the rice fields. They survive against many environmental stressors and are considered as a major pest in water-lodged cultivated area due to their intrusiveness, adaptation mechanisms and survivability. Therefore, there is a need for strategies to control their pop ...
