Malathion is a commonly used organophosphate pesticide on field crops, fruits, nut trees, vegetables, livestock, agricultural premises, and land. The approved uses also include mosquito and medfly control. These uses can result in human skin contact. The purpose of this study is to evaluate the human skin absorption of malathion for the purpose of assessing the risks associated with aqueous solution exposures following applications. Aerial applications can result in solubilized malathion in swimming pools and other waters that may be contacted. Human volunteers were selected and exposed to aqueous solutions of malathion at various concentrations. Participants submerged their arms and hands in twenty liters of dilute malathion solution in either a stagnant or stirred environment. The disappearance method was applied by measuring malathion concentrations in the water before and after human subject exposure to the water for various periods of time. Malathion was measured using Gas Chromatography. No
Induced degradation of Malathion in aqueous solutions with advanced oxidation processes (AOPs), using ultraviolet irradiation (UV), ozonation and chemical oxidation using (sodium hypochlorite, calcium hypochlorite, monochloride-isocyanuric acid (MCICA), dichloroiso-cyanuric acid (DCICA), trichloroisocyanuric acid (TCICA) was studied. Malathion and its degradation products were extracted using solid phase extraction (SPE) method, identified using GC-MS. Results showed that the degradation of malathion in aqueous solutions followed the first order reaction, and its half life was 2.37, 4.53, 6.64 and 8.84 h under ozonation, UV, 1.5% TCICA and 1.5% DCICA, respectively when malathion solutions treated for 12 h. The concentrations of chemical oxidative substances, active chlorine content and time of treatments had a significant effect on degradation rate of Malathion, which increased with increasing of each. The most enhancement of Malathion degradation was observed in treatment with ozonation, UV, ...
Aedes albopictus was bioassayed to determine resistance development to malathion (OP). Two methods were applied, including WHO larval bioassay to determine the susceptibility to lethal concentration (LC), and adult bioassay to determine lethal time (LT). Larvae from colonies that had undergone selection pressure with malathion to yield 50 mortality were further subjected to selection for subsequent 10 generations. Selection of Ae. albopictus with malathion could relatively induce a consistent resistance ratio of 1.0 throughout 10 generations. It was noted that Ae. albopictus larvae showed less susceptibility to malathion compared to adults. The susceptibility test of adult mosquitoes to diagnostic dosage of 5.0 malathion-impregnated paper showed a variety of susceptibility to malathion when compared to the susceptible strain. Bioassay results indicated that the LT 50 values of malathion-selected Ae. albopictus ranged between 11.5 - 58.8 minutes for ten consecutive generations. Biochemical enzyme ...
Malathion is an organophosphorous compound that inhibits cholinesterase enzyme activity. Malathion contains an interesting phosphinothioyl-thio ester as its active moiety where modification of acetylcholinesterase occurs. The action of Malathion on acetylcholinesterase has been correlated to prolonged modulation of the functioning of the cutaneous vasculature. Malathion is an organophosphate insecticide of relatively low human toxicity.

A laboratory study on the sublethal effects of malathion on the net-spinning behavior of the caddisfly larvae Hydropsycheslossonae was conducted in order to assess the potential of net anomalies as an indicator of chronic exposure to organophosphorus insecticides. Two anomalies were identified after chronic exposure to 0.01, 0.05, 0.1, 0.5 and 1.0 μg l−1 malathion. The first was a distortion of the midline meshes where the normal diamond shape structure was disrupted and the meshes were separated by extra strands (called midline anomaly). The second aberration observed was a significant decrease in net symmetry. Both anomalies were highly correlated to the toxic action of malathion, i.e. inhibition of the acetylcholinesterase enzyme (AChE). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analyses of capture nets did not show any modification of silk polypeptides after exposure to malathion, indicating that net distortions were not related to silk composition. Both anomalies seem ...
Malathion is a member of the organophosphate chemical family and is one of the least toxic pesticides in the group. Malathion is a cholinesterase inhibitor. Malathion by itself is not a strong cholinesterase inhibitor. It requires activation by conversion to its oxygen analog, malaoxon. Mosquitoes possess this enzyme. However, humans and other mammals possess a second enzyme which rapidly metabolizes malathion and malaoxon into non-active diacids. This make the chemical non-toxic to humans. Mosquitoes do not possess this second enzyme which makes it toxic to them. Malatahion is widely used in agriculture; by commercial and industrial and institutional organizations; and in mosquito abatement programs. It breaks down rapidly in the environment and does not accumulate in soil, water, or air. It is one of the most widely tested of the pesticides. It is non-carcinogenic, non-teratogenic, and non-mutagenic. ...
The Medicines Control Agency and Committee on Safety of Medicines are reviewing the evidence provided by "World in Action", and will consider the need for further studies or changes in the recommendations for use. Malathion is absorbed slowly through human skin and is rapidly detoxified in the blood and there is no evidence that people exposed to malathion through the use of head-lice and scabies treatments have experienced serious adverse effects. Product information for shampoos and lotions containing malathion warns against prolonged use (for example, stating that it should not be used more than once a week and for not more than three consecutive weeks). The papers referred to regarding organophosphate absorption relate to occupational exposure to malathion, that is long term chronic exposure or acute exposure to toxic doses. The safety limits advised for occupational exposure are not relevant to the medicinal use of malathion. ...
Malathion is a widely used organophosphate pesticide as it is applied to control a wide range of sucking and chewing pest of field crops, fruits and vegetables. The present study reports the isolation of malathion-degrading bacteria using enrichment technique. Morphological, biochemical and 16S rRNA identification was carried out. The analysis showed that one of the isolated bacteria was belonging to Bacillus genusand the other was assigned Pseudomonas aeruginosa. The two malathion-degrading isolates were grown in Minimal Salt Medium (MSM) containing different concentration of Malathion (6841 ppm, 14253 ppm, 28506 ppm and 42759 ppm). Malathion residues (degradation products) were measured with Gas Chromatography/Mass Spectrometry after 7 days of incubation at 35°C with the isolated strains in parallel with control samples. Results indicate that Pseudomonas aeruginosa and Bacillus spp. were able to utilize malathion a sole carbon and energy source even at high concentration and to degrade it ...

Plant growth is slow. Treatment. First, isolate all infested plants. This will help prevent any further spread of Aphids.. For light infestations, try dabbing the insects with a cotton swab soaked in rubbing alcohol (70 percent isopropyl). Also, use the alcohol to wipe away the honeydew so that Sooty Mold does not set in. If Sooty Mold has already set in, use the alcohol to gently remove it. After cleaning your Violet off with rubbing alcohol, hold the plant upside-down while thoroughly rinsing it with lukewarm water.. For heavier infestations, you may need to treat your Violets with Acephate (as directed on the label) or with Malathion (1 teaspoon of Malathion 50 per 4 liters of lukewarm water). Since Malathion may discolor flowers, Acephate is preferred. Acephate is available in household insect sprays. However, many of these sprays contain a specific additive which may damage the foliage of African Violets. Therefore, if available, use a soluble powder, and mix your own spray.. As an ...
Mealy Bug - It is essential that the mealy bug is killed promptly but the cotton-wool cover can repel any insecticide sprayed onto it, so often a wetting agent in the insecticide spray is required. The normal way of attacking the mealy bug is to use a contact insecticide such as malathion (not for Crassulaceae) or systemic insecticide usually based on a organophosphorus compound ( dimethoate is often recommended) While these can be quite effective many strains of mealy bug have built up some resistance to these and it may be necessary to try more than one type for effective control! Some insecticide such as one containing Malathion can be painted on with a fine brush, kept especially for this purpose. For large or widespread infestations, use regular applications (weekly for several weeks) A single application will often not be sufficient to eliminate all the insects and their young. Before spraying be sure that plant has been well watered a day prior to treating. This will decrease the risk of ...

[Objective] The aim was to study the effection of malathion on the activity of antioxidant enzgme of Perinereis.aibuhitensis Grube.[Method]Using the indoor simulation method,the acute toxic effects of various concentrations of organophosphorus pesticide malathion on Perinereis aibuhitensis Grube were determined. The median lethal concentration (LC50 ) of malathion to Perinereis aibuhitensis Grube for 96 h was 33.16 mg/L,and the safety concentration was 3.32 mg/L. The six treatments (0.001 8,0.018,0.18,1.8,3.6,9 mg/L) were set up ,and the Perinereis aibuhitensis Grude were exposed to those treatments for 3 d and 6 d respectively,which the superoxide dismutase (SOD)activity,peroxidase (POD) ,catalase (CAT) activity and malondialdehyde (MDA)content were examined.[Result] The results indicated that the CAT,SOD and POD were sensitive to the malathion,and were inhibited following a 3 d exposure to 0.001 8 mg/L . Malathion treatment led to an initial decline in CAT and SOD activity followed by a sharp increase

The soil sample was collected from Agriculture University Gwalior, Madhya Pradesh, India which is having a history of repeated pesticide application. Bacterium capable of degrading Malathion and Dichlorvos were isolated and identify as Staphylococcus sp. Micrococcus sp. Entrobacte sp. Bordetella sp. Pseudomonas sp. and Klebsella sp. The growth of all six pesticide degrading isolates was assessed in Mineral Salt Medium (MSM) canting 100 mg/lit of each pesticide. The maximum growth rate by the isolates Pseudomonas sp. AUG12 were 1.564 and 1.435 for Malathion and Dichlorvos respectively after 140 h Plate assay revealed that Pseudomonas sp. AUG12 could grow with high concentration of Malathion (1900 mg/lit) and Dichlorvos (1500 mg/lit). The total protein concentration was higher in the supernatant of Pseudomonas sp. AUG12 extracellular fraction which is 97 µg/mL for Malathion and 99 µg/mL for Dichlorvos. The beast Pseudomonas sp. AUG12 was therefore used in further experiment. The maximum growth ret of
We had a months-long infestation of these godawful things, and at first we tried to play by the rules of almighty Gov and our apartments managers. They swore that their heat treatment would work, but as far as I could tell all it did was vaguely annoy them. After the first time I found at least a hundred scouring the brick walls (scotch tape, by the way, is the best way Ive found to pick them up. No risk in getting their smelliness on you, and you can just fold it over and throw it away). The second time they did their heat treatment I found one crawling the wall THE SAME DAY. We lost furniture to bedbugs, clothing (burnt going through dryers) and endless time, all because of this mantra they pushed about the efficacy of their way, and it was just so much crap. My advise is to just save yourself the time, money, and stress by buying Malathion. It cost me ten dollars for the chemicals, I borrowed a sprayer, expended roughly two hours in moving things/vacuuming/spraying, and the results were ...
For home-owners. The insecticide Spinosad (e.g., Monterey Garden Insect Spray) is effective and has the least negative environmental effects of currently available products. Some spinosad products are sold to be applied with a hose-end sprayer, but a compressed-air sprayer will give more reliable coverage. Fertilome® Borer, Bagworm, Tent caterpillar and Leafminer spray (spinosad 0.5%) and Green Light® (spinosad 0.5%) are also labeled for use in bushberries and caneberries against fruit flies. The organophosphate insecticide malathion is widely available and will also control SWD, but malathion is very toxic to bees and natural enemies of other pests in the garden so care must be taken to keep the application on the target plant and avoid drift and runoff. Improper application also can result in injury to cherry trees. Because of the potential negative impact of malathion in the garden, use it only where you are certain you will have a SWD infestation, either because you had a problem last year ...
The effects of insecticide application on foraging and pollination by honeybees in toria (Brassica campestris var. toria) cultivar RSPT-1 were studied at Jammu (India).Under field conditions the application of betacylfluthrin, betacyfluthrin + imidacloprid and carbaryl resulted in 100% bee mortality within one hour of spraying. After 48 hours, 100% mortality was recorded in all the treatments except malathion (94%). The post-spraying effects of the insecticides were much higher during the first hour after treatment, but after 48 hr there was 100% mortality in all treatments except imidacloprid (43%). Residual effects after spraying were high for flowers sprayed with imidacloprid (76% mortality), demeton-o-methyl, carbaryl, and ethiprole, moderate for betacyfluthrin (49%), betacyfluthrin + imidacloprid, and profenophos, and low for malathion (12%). The residual effect decreases with time and after 96 hours of spraying, the residual effect was reduced in almost all the insecticides. The number of ...
