Evaluation of a New Thermal Fog Machine for Control of Adult Aedes albopictus in a Large Enclosed Space.

Testing of the PSO BASDKA-AC1200 multifunction ultrafine particle atomization machine, a thermal fog machine, with Aqualuer 20-20(®) (permethrin 20.6%, piperonyl butoxide 20.6%) was conducted against Aedes albopictus.

[Detecting the concentrations of bisphenol A (BPA) in air of workplaces with HPLC].

Objective: To establish the method of detecting the concentrations of bisphenol A (BPA)in air of workplaces with high performance liquid chromatographic (HPLC).

Methods: According to standards of methods for determining the chemical substances in workplace air, BPA in the air was collected by glass fiber filter, then dissolved by acetonitrile and determined by high performance liquid chromatography with FLD.

Results: There was a linear relationship within the range of 0.

Random repeated cross sectional study on breeding site characterization of Anopheles sinensis larvae in distinct villages of Yongcheng City, People's Republic of China.

Background: Characterizing the breeding site of Anopheles sinensis is of major importance for the transition from malaria control to elimination in China. However, little information is available especially regarding the characteristics and influencing factors of breeding sites of An. sinensis in Yongcheng City, a representative region of unstable malaria transmission in the Huang-Huai River region of central China.

The abundance and host-seeking behavior of culicine species (Diptera: Culicidae) and Anopheles sinensis in Yongcheng city, People's Republic of China.

Background: The knowledge of mosquito species diversity and the level of anthropophily exhibited by each species in a region are of great importance to the integrated vector control. Culicine species are the primary vectors of Japanese encephalitis (JE) virus and filariasis in China. Anopheles sinensis plays a major role in the maintenance of Plasmodium vivax malaria transmission in China.

[Study on Bartonella vinsonii berkhoffii isolated from blood of native dogs in China].

Objective: To isolate and identify Bartonella strains from native dogs in Shandong province in China.

Methods: EDTA-anticoagulated blood samples were collected from 71 native dogs in Yanggu county of Shandong province in March 2005. All isolates were grown on brain heart infusion agar plates containing 5% defibrinated rabbit blood.
