Relative influence of plant quality and natural enemies on the seasonal dynamics of Bemisia tabaci (Hemiptera: Aleyrodidae) in cotton.
The abundance and distribution of insect herbivores is determined by, among other things, plant quality and natural enemies. These two factors vary temporally and spatially, subsequently affecting sea...Read More
In vitro induction/inhibition of germinal vesicle breakdown (GVBD) in frog (Euphlyctis cyanophlyctis) oocytes by endocrine active compounds.
Oocyte maturation is transformation of oocytes into a fertilizable egg. This study examined the effects of four classes of chemicals: 1) acephate (organophosphate); 2) atrazine (herbicide); 3) cyperme...Read More
Metabolomic analysis of the toxic effect of chronic low-dose exposure to acephate on rats using ultra-performance liquid chromatography/mass spectrometry.
To study the toxic effect of chronic exposure to acephate at low-dose levels, a metabolomics approach based on ultra-performance liquid chromatography/mass spectrometry (UPLC-MS) was applied. Three di...Read More
Microarray analysis of gene regulations and potential association with acephate-resistance and fitness cost in Lygus lineolaris.
The tarnished plant bug has become increasingly resistant to organophosphates in recent years. To better understand acephate resistance mechanisms, biological, biochemical, and molecular experiments w...Read More
Immunotoxicity for subacute exposure to acephate (O,S-dimethyl-acetylphosphoramidothioate) was assessed in day old White Leghorn (WLH) cockerel chicks. The chicks were divided into five groups. Groups...Read More
Sol-gel immobilized biosensor for the detection of organophosphorous pesticides: a voltammetric method.
Organophosphorous compounds are important neuroactive molecules whose presence exhibits significant analytical challenges. An acetylcholinesterase (AChE) based amperometric biosensor was developed by ...Read More
Ultrasensitively sensing acephate using molecular imprinting techniques on a surface plasmon resonance sensor
An ultrathin molecularly imprinted polymer film was anchored on an Au surface for fabricating a surface plasmon resonance sensor sensitive to acephate by a surface-bound photo-radical initiator. The p...Read More
Mango, the major fruit crop of India is affected by stone weevil, which can cause serious damage to the fruits. Acephate gives good control of mango stone weevil. Residues of acephate and its major me...Read More
Limited data document the multiple and repeated pesticide absorption experienced by farmworkers in an agricultural season or their risk factors.Data were collected from 196 farmworkers four times at m...Read More
Influence of polyphenolic extracts from Enydra fluctuans on oxidative stress induced by acephate in rats
Acephate, an organophosphorus pesticide, has been proved to play an important role in tissue damage by inducing oxidative stress through the release of free radicals. The aim of this study was to eval...Read More
[Development of a novel multi-functional adsorbent bearing with long-chain hydrophobic and anion exchange groups for the simple and rapid determination of residual acephate in vegetables]
A novel multi-functional adsorbent (RP-SAX adsorbent) bearing hydrophobic and anion exchange groups was synthesized for the simple and rapid determination of residual acephate (AP) in vegetables. Macr...Read More
Inhibition of cholinesterase activity by soil extracts and predicted environmental concentrations (PEC) to select relevant pesticides in polluted soils.
The correlation of predicted environmental concentrations (PEC) with cholinesterase activity inhibition detected in soil extracts was determined. PEC was derived from organophosphate (OP) and carbamat...Read More
Acephate is poorly sorbed to soil, thus the risk of leaching to the aquatic environment is high if it is not quickly degraded. The effect of soil moisture, temperature, microbial activity and applicat...Read More
Controlled release formulations of insecticide acephate (O,S-dimethyl acetylphosphoramidothioate) have been prepared using commercially available polyvinyl chloride, carboxy methyl cellulose and carbo...Read More
