Objective To investigate the species composition of murine-like animals in the Macheng city, Yingshan county, Suizhou city, Xian'an district, Chongyang county, and Xingshan county of Hubei province, China, where there has been high incidence of severe fever with thrombocytopenia syndrome (SFTS), and to provide a scientific basis for the control of this disease. Methods The night trapping method was used to capture murine-like animals. Results Niviventer confucianus was the dominant species outdoors in Guangshui county and Sui county of Suizhou city, accounting for 58.88% of all captured rodents in this area. N. confucianus was the dominant species in Xian'an district, accounting for 68.18% of all captured rodents in this area. Crocidura attenuata was the dominant species in Macheng city and Xingshan county, accounting for 40.48% and 66.67%, respectively, of all captured rodents in local areas. Rattus tanezumi was the dominant species in Yingshan county and Chongyang county, accounting for 43.75% and 47.06%, respectively, of all captured rodents in local areas. Most of captured rodents were female. Conclusion The species composition of outdoor rodents varies greatly between the epidemic areas of SFTS in Hubei province, with N. confucianus, R. tanezumi, and C. attenuata as the dominant species, and most of the captured rodents are female.

Objective To observe the control effects of 10% boric acid gel bait on cockroaches in the laboratory and field and compare it with residual spray in killing cockroaches. Methods The killing effects of 10% boric acid gel bait and residual spray were observed in the laboratory and simulated field according to the national standards GB/T 17917.7-2009 and GB/T 17917.10-2009. The decrease in cockroach density was determined by visual measurement after residual spray and application of gel bait in the field, and the killing effect was evaluated accordingly. Results In the laboratory and simulated field, all Blattella germanica died 2 d after treatment. In the field, the average density of B. germanica was 169.25/15 min before residual spray; the density decreased by 9.60% and 6.29% in the first and second weeks after residual spray of 10% cis-cypermethrin suspoemulsion plus 80% DDVP; then, residual spray of 10% cis-cypermethrin emulsion plus 20% propoxur EC was performed, and the density decreased by 6.63% and 5.51% in the third and fourth weeks. Finally, 10% boric acid gel was used, and the average density of B. germanica decreased by 94.10% and 100% in the first and second weeks after treatment. The average density of B. germanica was 1.38/15 min 1 month later. Conclusion The B. germanica population with high insecticide resistance is difficult to be control by residual spray, but 10% boric acid gel bait has good control effect on cockroaches and causes little insecticide resistance. Gel bait is recommendable for cockroach control.

Vector monitoring is an important approach for the prevention and control of dengue fever. Scientific methodology plays a leading role in dengue control. This study reviews the advances in multiple monitoring Methods for vectors of dengue fever, compares the strengths and weaknesses, and analyzes the existing problems in the domestic monitoring approaches. Introducing an epidemiological method for monitoring adult mosquitoes according to China’s current conditions, this article looks forward to the development trend of vector monitoring modes in future.

【Abstract】 Objective To learn the resistance situation of Musca domestica from different areas in Hubei province to common insecticides and study its control measures.  Methods Topical application was used in this study.  Results The surveillance results indicated the average LD50 values of DDVP to housefly from different areas was 0.2256, 0.1908 and 0.4428 μg/housefly from 2005 to 2007, respectively. The average LD50 of alpha?cypermethrin was 0.0841 and 0.1102 μg/housefly in 2006 and 2007, respectively. The average LD50 of deltamethrin was 0.0371 and 0.0825 μg/housefly in 2005 and 2007, respectively. The average LD50 of etramethrin in 2005 and 2006 was 0.3952 and 0.2894 μg/housefly, respectively. The average LD50 of acetophenate in 2005 and 2007 was 0.3264 and 0. 3487 μg/housefly. Conclusion M.domestica had high resistance to organic phosphorus and pyrethrum insecticide in Hubei province. No obvious resistance against acetophenate had been found. The mixed and rotation use of insecticides contributed to the control the resistance development of M.domestica.

Objective To study the resistant development of Rattus norvegicus to anticoagulant rodenticide after its application in Qichun county.Methods The resistance of R.norvegicus was tested according to the method established by Rodenticide-resistance Monitoring Cooperation Group of China.Results The resistance of R.norvegicus was detected in 1990,1995,2000,2002,2005 and 2007,respectively.There were 208 rodents tested,and only one rodent survived in each of three times resistance monitoring.Whether the test rodent were male or female,the minimum and maximum average lethal dosages in 2000-2008 resistance monitoring was all lower than that in 1995.But the average lethal time postponed a little compared to that in 1990.Conclusion After the application of anticoagulant rodenticide for 23 years in Qichun, R.norvegicus was still highly susceptible to the first-generation anticoagulant rodenticides,and its tolerance capability was lower than that of R.tanezumi and Mus musculus.Therefore,the anticoagulant rodenticides could be still used to kill R.norvegicus.

Objective To evaluate diseases prevention and control in the reservoir before the sluicing,and to understand the morbidity level and trend of zoonosis in the population in the Three Gorges Area after the sluicing.Methods The standard disinfection and vector control practises issued by China CDC,to analysis the data of zoonosis in Three Gorges area.Results After the clearance of waste out of the reservoir before the slucing,no outbreak of Epidemic Hemorrhagic Fever,leptospirosis and Encephalitis B is reported.Conclusion Waste clearance can protect the water from being polluted after the sluicing,no outbreak of zoonosis-borne diseases is reported,and no significant effect of environment change on the zoonnosis is found.

Objective To investigate the change of the density of rodents before and after the 2nd phase water storage in Three Gorges reservoir. Methods Mousetraps were used to detect the density of rodents in different periods,and Bromadiolone was applied in large area before water storage. Results The indoor density of rodents before water storage is 4.07%,while it is 3.17% after water storage;the outdoor density of rodents before water storage is 3.17%,and it is 2.35% after water storage. Conclusion The density of rodents in Three Gorges reservoir before and after the 2nd phase water storage do not change greatly.

Objective:To study the efficacy of killing insect and anti-mould of Wa Wang.Method:To test the efficacy of Wa Wang manufacture to kill 3 public health insects on 3 different surfaces and Candida albicans restrain.Results:It showed that Wa Wang could quickly kill the insects on 3 different kinds of surfaces.The efficacy was lasting go to 75 days for <>i ciatus and Musca domestica,and go days for Blattella germanica.0.25% Wa Wang could efficiently restrain Candida albicans(ATCC-10231).Conclusion:The insecticide was good for killing public health insects and anti-mould.
