Field-simulated residual efficacy of betacyfluthrin against Anopheles sinensis Wiedemann.
نویسندگان
چکیده
The residual efficacy of a relatively new pyrethroid, betacyfluthrin was compared with DDT against Anopheles sinensis Wiedemann in some village houses in Penang, Malaysia, for a period of 30 weeks. Efficacy was determined by exposing laboratory-cultured An. sinensis mosquitos to treated wall surfaces with either betacyfluthrin at 15 and 25 mg/m2 or DDT at 2,000 mg/m2 for one hour. Betacyfluthrin provided a longer residual effect (up to 210 days with > 70% mortality) compared with DDT. The potential of betacyfluthrin as a candidate for residual spraying for malaria control is discussed.

A Lectotype Designation and Description for Anopheles ( An . ) sinensis Wiedemann 1828 , with a Discussion ofxe Classification and Vector Status
The true identity of Anopheles sinensis is established by the designation and description of a lectotype. The status of An. lesteri and other cryptic species hidden under the name "sinensis" in China, is summarized. The confusion produced by these cryptic species, in regard to our understanding of the vector capabilities of sinensis, is also discussed. Characters are noted that can be used to s...

Probabilities of pyrethroid resistant genotypes in natural populations of Anopheles sinensis Wiedemann were measured with deltamethrin and permethrin. The median lethal concentrations (LC50s) of deltamethrin and permethrin in the susceptible larval population were 0.0209 and 0.1747 ppm, respectively. Under dosages that produced 99% mortality in susceptible laboratory strains of larvae, the leth...
متن کاملBiology, Bionomics and Molecular Biology of Anopheles sinensis Wiedemann 1828 (Diptera: Culicidae), Main Malaria Vector in China
China has set a goal to eliminate all malaria in the country by 2020, but it is unclear if current understanding of malaria vectors and transmission is sufficient to achieve this objective. Anopheles sinensis is the most widespread malaria vector specie in China, which is also responsible for vivax malaria outbreak in central China. We reviewed literature from 1954 to 2016 on An. sinensis with ...
