Toxicokinetics of temephos after oral administration to adult male rats

Archives of Toxicology, 2021
Temephos (Tem) is the larvicide of choice to control mosquito transmission of dengue, Zika, and chikungunya. The toxicokinetic and toxicological information of temephos is very limited. The aim of this work was to determine the toxicokinetics and dosimetry of temephos and its metabolites.

Temephos (Abate�) metabolism and toxicity in rats

Archives of Environmental Contamination and Toxicology, 1985
In order to clarifyin vivo relationships between the mammalian metabolism and toxicity of temephos, an organophosphate insecticide, activities of acetylcholinesterase and hepatic mixed function oxidases (MFO) were evaluated in adult female Sprague-Dawley rats after acute and subchronic temephos exposures.

Toxicity of the Organophosphorus Pesticide Temephos

Indonesian Journal of Life Sciences, 2019
Dengue is a major public health problem in tropical urban areas, not only because it can quickly progress from the mild dengue fever to the deadly dengue hemorrhagic fever, but also because there is no single cure or licensed vaccine available to this day. To control the disease, the World Health Organization has recommended insecticides to control the

Efficient photocatalytic elimination of Temephos pesticide using ZnO nanoflowers

Journal of Photochemistry and Photobiology A: Chemistry, 2020
Abstract Temephos (Tem) is a widely used pesticide to control mosquito’s proliferation in tropical countries. This pesticide is put in stagnant water bodies where mosquitoes reproduce, killing larvae effectively. Recently, Tem has been identified as a DNA damaging agent; despite, people use it unmoderated in water reservoirs for personal consumption.

Temephos Collars for Control of Fleas on Dogs and Cats

American Journal of Veterinary Research, 1977
SUMMARY Efficacy of polyvinyl chloride collars containing temephos [0,0'-(thiodi-4,1-phenylene) 0,0,0',0'-tetramethyl bis-(phosphorothioate)] was evaluated in dogs and cats against the cat flea (Ctenocephalides felis). Over a period of 42 weeks, collared (treated) and control dogs were experimentally infested with 100 fleas 23 times, and control and ...

Controlled Release Temephos: Laboratory and Field Evaluations

1981
The development of controlled-release pesticides based upon the monolithic dispersion of a chemical agent in a polymer has been described in detail elsewhere.1 Temephos, 0,0,0’,0’-tetramethyl-0,0-thiodi-p-phenylene phosphorothioate (C.A. Registry #3383–96–8), was incorporated in elastomeric matrices and a diffusion-dissolution type release mechanism ...

Human Biotransformation Pathway of Temephos Using an In Silico Approach

Chemical Research in Toxicology, 2020
Temephos is an organophosphorothioate (OPT) larvicide used for controlling vectors of diseases such as dengue, chikungunya, and Zika. OPTs require a metabolic activation mediated by cytochrome P540 (CYP) to cause toxic effects, such as acetylcholinesterase (AChE) activity inhibition.

Comparative modification of insecticide‐resistance spectrum of Culex pipiens fatigans wied. By selection with temephos and temephos/synergist combinations

Pesticide Science, 1979
AbstractThe evolution of strong organophosphorus multiresistance, suppressible by S,S,S‐tributyl phosphorotrithioate (TBPT), in a California strain of Culex pipiens fatigans was examined by further selection with temephos, alone and in combination with the synergists TBPT or piperonyl butoxide (PB).

Insecticidal Activity of Temephos Against Ctenocephalides felis on Dogs and Cats

American Journal of Veterinary Research, 1975
SUMMARY Dogs and cats were treated with 2% temephos [0,0′-(thiodi-p-phenylene)0,0′,0′-tetramethyl bis (phosphorothioate)] powder to evaluate its insecticidal activity against the cat flea (Ctenocephalides felis). Dogs and cats were infested each week with approximately 100 unfed, unsexed fleas less than 14 days old. Live-flea counts were made each day.
