Cytostatic and genotoxic effect of temephos in human lymphocytes and HepG2 cells

Toxicology in Vitro, 2015
Temephos is an organophosphorus pesticide that is used in control campaigns against Aedes aegypti mosquitoes, which transmit dengue. In spite of the widespread use of temephos, few studies have examined its genotoxic potential. The aim of this study was to evaluate the cytotoxic, cytostatic and genotoxic effects of temephos in human lymphocytes and ...

Effects of pesticide temephos on the gills of Aphanius dispar (Pisces: Cyprinodontidae)

Tissue and Cell, 2011
The changes in the behavior of Aphanius dispar, a cyprinodont fish when exposed to different concentrations of temephos, an organophosphorus pesticide widely used to control mosquito larvae in aquatic habitats are noted. The histopathology of gills exposed to temephos is studied in detail using light microscopy (LM), transmission electron microscopy ...

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.

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).

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 ...

[Effect of temephos on acetylcholinesterase activity in the brain of Tilapia guineensis. 3: Comparative effect of temephos and 3 substitute insecticides].

Toxicological European research. Recherche europeenne en toxicologie, 1983
The Onchocerciasis Control Programme (OCP) is realized in the major part of the treated area by weekly applications of temephos in biotopes of simulles larvae. This insecticide is very effective and its impact on the aquatic fauna is evaluated by means of periodic samplings of the fauna. Therefore, the most sensitive way of tracking down fish poisoning

[Evaluation of the efficacy of temephos in the campaign against dracunculosis].

Annales de la Societe belge de medecine tropicale, 1992
Efficacy of water source treatment with temephos 200 EC had been tested with three methods after treatment of a natural reservoir in a temporary river bed. 1. Residual pesticide in water treatment was measured with a biological test based on the pesticide toxicity on mosquito larvae from a laboratory stock for which the standard LD50 for the considered
