  • Temefos or Temephos (trade name Abate) is an organophosphate larvicide used to treat water infested with disease-carrying insects including mosquitoes, midges, and black fly larvae.
  • Temephos is a General Use Pesticide.
  • Temephos (Abate) is an Organo-phosphorus compound.
  • Its chemical formula is 0,0,0,0-tetra Methyl 0,0-thio-dephenyle phosphorothioate.
  • Temephos is a white, crystalline solid in its pure form. The technical grade is a brown viscous liquid.
  • In the developing world where the vector-borne disease dengue fever is endemic, temephos is widely used and applied by both
    private and public pest control in areas of standing water where the Aedes aegypti mosquito breeds in order to reduce the population
    of this disease-carrying insect.
  • Temephos can be extracted by using liquid–liquid or a solid-phase extraction method.
  • Temephos solution were provided by Funasa or prepared from the 98% temephos standard solution. Solution concentration and purity were verified by gas chromatography using a flame photometric detector and a mass spectrometer detector.
  • Temephos is also used in the Guinea Worm Eradication program to kill water fleas that carry guinea worm larvae.
  • It is used in lakes, ponds and wetlands.
  • It also may be used to control fleas on dogs and cats and to control lice on humans.
  • Temephos is also used experimentally on cotton, alfalfa, citrus and other crops for control of cutworms, thrips on citrus and Lygus bugs.
  • It is sometimes mixed with other insecticides for broader spectrum control.
  • It is also used as a formulated powder for the control of body lice.
  • This is the only organophosphate pesticide registered with the EPA for larvicidal use in the USA.
  • It is considered an important management tool for mosquito control programmes, being used to help prevent development of
    resistance to the bacterial larvicides.
  • Annual usage is approximately 25,000 to 40,000 pounds of active ingredient per year.
  • Temephos use has declined in recent years due to deletion of the use on citrus.
  • Temephos was first registered in the United States in 1965 by American Cyanamid Company for a number of uses including citrus
    fruits, pet collars, and mosquito control.
  • Temephos is recommended by WHO for addition to potable water as larvicide treatment at an application rate not exceeding 1 mg/l.
  • Temephos can be safely used in drinking water as it has a low mammalian toxicity.
  • This chemical was first introduced for mosquito larval control in Thailand in 1968 by the Aedes Research Unit funded by the
    World Health Organization (WHO) and later promoted on nationwide basis in 1978 in conjunction with primary health care, mainly
    in urban areas.
  • In rural areas, the percentages of rural households that applied temephos to storage containers meant for washing, bathing and flushing toilets amounted to 54%, 59%, 55% respectively.
  • Temephos is a larvacide which effectively controls the vectors of human diseases such as Malaria, Onchocerciasis, Epidemic Typhus Fever, Filariasis, Dracunculiasis, Yellow Fever, Dengue and various other arbovirus diseases.
  • The level of temephos resistance was detected in a microplate by biochemical assay using WHO
    bioassay technique.
  • The concentration and purity of temephos solutions were verified by gas chromatography.
  • Resistance to temephos by A. aegypti has been seen in Brazil.
  • The Brazilian Aedes aegypti resistance monitoring program detected temephos resistance in A. aegypti populations from several localities in the country in 1999.
  • The efficacy of a larvicide, temephos, for controlling Ae. aegypti was evaluated in a
    cemetery in Buenos Aires, Argentina.
  • Slow-release larvicides as temephos can reduce the frequency and cost of insecticide application
    to control mosquito populations.
  • The use of temephos in an environment with high availability of potential breeding sites was effective in reducing Ae. aegypti
  • In general, tendency of resistance to temephos in Ae. aegypti was most prevalent in Nakhon Sawan and Nakhon Ratchasima, located in the northcentral and northeastern parts of Thailand.
  • Temephos has been widely used throughout the country, naturally resistance was focal.
  • In urban areas, the standard packages available facilitated the correct use of temephos in dragon jars used for storage of water for drinking purposes (60 to 200 litres).
  • Temephos was more widely used in rural areas than in urban settings with 60% of rural households
    and only 25% of urban households reporting the use of temephos in at least one container in the past 12 months.
