Susceptibility of Aedes albopictus from China to insecticides, and mechanism of DDT resistance.
نویسندگان
چکیده
Aedes albopictus collected from urban districts of China (12 strains) has developed high levels of DDT resistance, while 2 strains collected from rural areas remain susceptible. The mechanism of DDT resistance was due to intensified activity of DDT-dehydrochlorinase, but the penetration of DDT into the mosquito body is also different. This may possibly have had some influence on the resistance levels of some strains, but it seems unlikely that was the main mechanism of DDT resistance.

Status of insecticide resistance and detoxifying enzyme activity of Aedes albopictus population in Sonitpur district of Assam, India
Sonitpur district, Assam (India) is well known for malaria incidence since many years. The extensive use of insecticides for the control of malaria and other vector species is being carried out for vector management. The insecticide resistance status of Aedes albopictus (Diptera: Culicidae) to DDT (dichloro-diphenyl-trichloroethane) and deltamethrin was studied in the Sonitpur district of Assam...

BACKGROUND Aedes albopictus is distributed widely in China, as a primary vector of Dengue fever and Chikungunya fever in south of China. Chemical insecticide control is one of the integrated programmes to prevent mosquito-borne diseases. Long-term applications of pyrethroids have resulted in the development of resistance in Ae. albopictus populations in China. However, the susceptibility of Ae....

Aedes albopictus (Skuse) is an invasive mosquito that has become an important vector of chikungunya and dengue viruses. Immature Ae. albopictus thrive in backyard household containers that require treatment with larvicides and when adult populations reach pest levels or disease transmission is ongoing, adulticiding is often required. To assess the feasibility of control of USA populations, we t...
متن کاملStatus of DDT and pyrethroid resistance in Indian Aedes albopictus and absence of knockdown resistance (kdr) mutation.
BACKGROUND & OBJECTIVES Aedes albopictus is one of the vectors for dengue and chikungunya and emergence of pyrethroid resistance in this species could be of a major concern in controlling the vector. This study reports insecticide susceptibility status of Ae. albopictus to DDT and pyrethroids in some Indian populations and status of presence of knockdown resistance (kdr) mutations. METHODS Th...

BACKGROUND The control and prevention of dengue largely depends on vector control measures, environmental management, and personal protection. Dengue control programmes are facing great challenges due to development of insecticide resistance among vector mosquitoes. Information on susceptibility status to different insecticides is important for national programmes to formulate vector control st...
