Inhibition and recovery of cholinesterases in Odontophrynus americanus tadpoles exposed to fenitrothion
(Triveni Enterprises, 2009-12)
We determined the levels of brain acetylcholinesterase (AChE) and tail butyrylcholinesterase (BChE) activities in tadpoles of Odontophrynus americanus exposed to a commercial formulation of fenitrothion. The mean brain ...
Study of biochemical biomarkers in freshwater prawn Macrobrachium borellii (Crustacea: Palaemonidae) exposed to organophosphate fenitrothion
(Academic Press Inc Elsevier Science, 2013-07-20)
Several agrochemicals like organophosphates are extensively used to control pests in agricultural practices but they also adversely affect non-target fauna. The effect of organophosphorous fenitrothion on the prawn ...
Solid-state structures and thermal properties of inclusion complexes of the organophosphate insecticide fenitrothion with permethylated cyclodextrins
(Elsevier, 2010-01)
The X-ray crystal structures and thermal stabilities of the inclusion complexes formed between the organophosphate insecticide fenitrothion [O,O-dimethyl O-(3-methyl-4-nitrophenyl) phosphorothioate] and the host compounds ...
Toxicity of non-pyrethroid insecticides against Triatoma infestans (Hemiptera: Reduviidae)
(Fundação Oswaldo Cruz, 2012-08)
Triatoma infestans (Klug) is the main vector of Chagas disease, which is a public health concern in most Latin American countries. The prevention of Chagas disease is based on the chemical control of the vector using ...
Comparative analysis of complexation of pesticides (fenitrothion, methylparathion, parathion) and their carboxylic ester analogues by β-cyclodextrin. Theoretical semiempirical calculations
(Springer, 2009-07)
The complexation by β-cyclodextrin (β-CD) of three organophosphorus pesticides, fenitrothion, parathion and methylparathion, and of their carboxylic ester analogues was analyzed using PM3 and molecular mechanics methods. ...
Predator-prey interactions between Synbranchus marmoratus (Teleostei: Synbranchidae) and Hypsiboas pulchellus tadpoles (Amphibia: Hylidae): Importance of lateral line in nocturnal predation and effects of fenitrothion exposure
(Pergamon-Elsevier Science Ltd, 2010-11)
Environmental contaminants can disrupt interactions between aquatic species by altering community structure. We explored predator-prey interactions between marbled swamp juvenile eels (Synbranchus marmoratus; predator) and ...
Relative Contribution of Monooxygenase and Esterase to Pyrethroid Resistance in Triatoma infestans (Hemiptera: Reduviidae) from Argentina and Bolivia
(Entomological Society of America, 2008-03)
Recently, high resistance to pyrethroid insecticides has been associated with ineffective field treatments against Triatoma infestans (Klug) in northern Argentina. Samples were collected from two areas in Argentina (Salta ...
Ecological Risk Assessment (ERA) of pesticides from freshwater ecosystems in the Pampas region of Argentina: Legacy and current use chemicals contribution
(Elsevier Science, 2019-11)
Agricultural production in the Pampas region is one of the most important economic activities in Argentina. However, the possible environmental effects related to the growth of this activity in the last years have not been ...
Coacervative microextraction ultrasound-assisted back-extraction technique for determination of organophosphates pesticides in honey samples by gas chromatography–mass spectrometry
(Elsevier Science, 2010-10)
Coacervative microextraction ultrasound-assisted back-extraction technique (CME-UABE)is proposed for the first time for extracting and preconcentrating organophosphates pesticides (OPPs) from honey samples prior to gas ...
Cuantificación de plaguicidas residuales en granos de maíz (Zea mays L.) aplicando técnicas de evaluación residual
(Asociación Revista Venezolana de Ciencia y Tecnología de Alimentos, 2014-06)
El empleo de plaguicidas en la producción agrícola ha tomado marcada importancia para muchos sectores de la sociedad. Los productores agropecuarios necesitan realizar un tratamiento fitoterapeútico efectivo y la utilización ...
