Malathion is an organophosphate pesticide commonly used on field crops, fruit trees, livestock, agriculture, and for mosquito and medfly control. Aerial applications can result in solubilized malathion in swimming pools and other recreational waters that may come into contact with human skin. To evaluate the human skin absorption of malathion for the assessment of risk associated with human exp...

Malathion in-vitro biodegradation study was conducted in liquid medium with five bacterial strains labeled S1, S2, S3, S4 and S5 isolated from newly reclaimed agricultural soil. Malathion residues were measured at successive intervals until 30 days after incubation, paralleled with control samples. Malathion Recovery rate was performed at 0.1 and one mg kg, achieved values were 91.30 and 98.70%...

Objective(s): The aim of this study was to determine the protective role of ascorbic acid on apoptosis and proliferation of spermatogonia and primary spermatocyte cells after malathion administration as an organophosphate pesticide in rat testis.Materials and Methods: Thirty male Wistar rats were randomly divided into five groups of 6 ra...

Among organophosphorus pesticides, malathion is considered a relatively safe compound. Malathion, however, functions by inhibiting cholinesterase (ChE) enzymes of the nervous system in both vertebrate and invertebrate organisms. The inactivation of ChE by malathion is therefore a useful indicator of exposure. Because of the increased application of these pesticides, their entry into various env...

The penetration of (14)C-labelled malathion was found to be similar in two bedbug strains, of which one was susceptible and the other moderately resistant to a range of organophosphorus insecticides. The latter strain was especially resistant to malathion and fenchlorphos, but was not resistant to organophosphates or (significantly) to organochlorine insecticides. There was no difference in ace...

BACKGROUND Recent studies indicate that infestations of psocids pose a new risk for global food security. Among the psocids species, Liposcelis bostrychophila Badonnel has gained recognition in importance because of its parthenogenic reproduction, rapid adaptation, and increased worldwide distribution. To date, the molecular data available for L. bostrychophila is largely limited to genes ident...

Malathion has a broad range of toxicities while its reproductive effects have not been fully elucidated. In this study, we treated animals with malathion by gavage at doses of 0, 33.75, 54, and 108 mg/kg for 60 days and evaluated the alterations in histology, biochemistry and serology. Malathion caused the reduction in the sperm counts and motility. The reduced body and testis weights were coup...

Regardless of toxicity of nanoparticles, cerium oxide nanoparticles (CeNPs) are emerging as a multi-functional agent for biomedical purposes. On the other hand, Organophosphorus pesticides, like malathion, are inevitably found in the environment. The common involving pathway CeNPs and malathion share is oxidative stress. Therefore, we conducted this study to find the possible neutralizing or sy...

Background: Programmatic monitoring of insecticide resistance in disease vectors is mostly done on a large scale, often focusing on differences between districts, regions or countries. However, local heterogeneities in residual malaria transmission imply the need for finer-scale data. This study reports small-scale variations of insecticide susceptibility in Anopheles arabiensis between three n...

Abundant reports on stunted growth in fishes following pesticides exposure are available; however, mechanism underlying it is rarely studied. Since hormones are well known to play vital role in regulation of metabolic activities and general body growth, present study was conducted to investigate the effects of malathion (an organophosphorous pesticide) on metabolic hormones, responsible for pro...
