In Cambodia, the main vector of dengue fever is the mosquito Aedes aegypti, a white and black stripped mosquito active during the day.
This mosquito is mainly found in human breeding sites, especially in water jars. It is present both in the cities and rural areas. To control this mosquito, the insecticides used in Cambodia are temephos mainly known as Abate in Cambodia (used against larvae mainly in the jars), deltamethrin and permethrin against adults (by sprayings).
A related scientific article co-authored by the Pasteur Institute of Cambodia, CNM (Cambodia National Malaria Center), Malaria Consortium and NAMRU (The U.S. Naval Medical Research Unit) was published in Asia Pacific Journal of Public Health, a peer-reviewed journal focused on health issues in the Asia-Pacific Region.
This article demonstrates a very high level of insecticides resistance.
It means that the three currently used insecticides in Cambodia are now totally ineffective. It results that a change of strategy used in vector control against Dengue vectors is recommended.
