The aerial application of malathion, a widely used organophosphate insecticide, has raised public concerns about potential adverse health effects. We therefore studied micronucleus formation in human lymphocytes as a biomarker of genotoxicity both in vitro and in vivo. Lymphocytes were cultured either as whole blood or after Ficoll isolation and treated with malathion in doses from 5 to 100 mic...

conclusions in conclusion, at measurement can be beneficial for the safety or recovery of malathion-induced toxic injury in liver tissue and liver mitochondria. results in liver tissue, the activity of lpo and cat was higher in the malathion group in comparison to controls. at reduced malathion-induced lpo, sod, cat, and gpx in rat liver. coadministration of at with malathion improved lpo, sod,...

BACKGROUND Head-lice infestation is prevalent worldwide, especially in children 3 to 11 years old. Topical insecticides (i.e., pyrethroids and malathion) used as a lotion, applied twice at an interval of 7 to 11 days, are typically used for treatment. Resistance of lice to insecticides, particularly pyrethroids, results in treatment failure. The efficacy of alternative agents is controversial. ...

Invertebrate organisms mostly have innate immune system. Hemocytes are the cells of immunity in invertebrates. Our study was designed to observe effect malathion insecticide on system, function and hemocytes Drosophila melanogaster. A hemocytometer used for total count which showed a reduced percentage live (from 91.63% 44.57%) due treatment. For differential count, hemolymph spread as smear cl...

Records of 92 cases of acute organophosphorus (OP) insecticide poisoning were analysed. Of the patients 91% were under 30 years of age and 86% were males. The common agents were Dimethoate, Methamidophos, Malathion, Monocrotophos and Fenthion. Poisoning was due to ingestion with suicidal intent in the majority. In addition to the acute cholinergic features, the other important manifestations we...

<p><strong>Background.</strong> Resistance to an insecticide is what determines its effectiveness and the lack of information limits in control boll weevil cotton crops. <strong>Objective.</strong> The objective study was determine susceptibility (<em>Anthonomus grandis</em> Boheman) malathion Laguna, Mexico. Currently, this pest considered as one with ...

The correlation between malathion resistance and fecundity was investigated in the fruit fly, Drosophila melanogaster. Previous studies have shown that insecticide resistance is negatively correlated with reproductive components in insects. To investigate this relationship, the fecundity (egg production) was determined in 2 natural and 2 esterase 6 (Est-6) marker populations (4016 and 4211) and...

BACKGROUND The control and prevention of dengue largely depends on vector control measures, environmental management, and personal protection. Dengue control programmes are facing great challenges due to development of insecticide resistance among vector mosquitoes. Information on susceptibility status to different insecticides is important for national programmes to formulate vector control st...

BACKGROUND & OBJECTIVES The major malaria vector, Anopheles culicifacies Giles is reported to contribute ~ 65% of the malaria cases in India. This species developed resistance to DDT and later to HCH, malathion and also to pyrethroids in some states due to their use in the national malaria control programme. In the present study, insecticide susceptibility of this species was monitored in four ...
