3.3.2. Evaluate the efficiency of indoor ULV spray fludora co-max in Dien Khanh district The vector surveillance in both Dien Phu commune (intervention commune) and Dien Dien commune (control) 1 day before the intervention. Spraying insecticides fludora co-max in Dien Phu commune. The results are shown in figure 6:

Figure 6. Density and house infested with Ae.aegypti in intervention commune (CT) compared with control commune (ĐC) The results compared with the mosquito density index in the intervention and the control commune before the intervention were similar, corresponding to the density of 0.32 to 0.34 mosquitos / house at the time before 1 day of the survey. not statistically significant (p = 0.67> 0.05). After spraying fludora co-max 1 day, the mosquito density in the intervention commune decreased to 0.17 mosquito/ house compared to 0.41 mosquito / house in the control commune, the difference was statistically significant (p = 0.02 <0.05). After sprayed 7 days, the mosquito density in the intervention commune was 0.24 mosquitos / house compared with 0.5 head / house in the control commune, the results were statistically significant. p = 0.04 <0.05). The mosquito density in the intervention commune increased again and reached 0.36 mosquito / house compared to the control point of 0.44 mosquito / house after 10 days of testing, the difference was not statistically significant (p = 0.29 > 0.05). The efficiency of spraying ULV on fludora co-max reached 7 days after spraying to reduce the density of mosquito Ae. aegypti resistant strain in Dien Khanh. Table 6.
