Figure 3.12 Comparison of IUDs with larvae in sumilarv 2MR insecticidely interfered commune with control commune without insecticide intervention Comparing the percentage of water container infested larvae (WCIL) in 2 communes, 2MR sumilarv insecticide reduces the percentage of WCIL with larvae Ae.aegypti in the narrow field of intervention commune. After 30 days of intervention, sumilarv 2MR reduced the proportion of houses with Ae.aegypti larvae to 32% compared with 82% of WCIL with Ae.aegypti larvae in the control commune. Comparing the difference between the larvae indicators: Breteau, percentage of households with larvae and percentage of WCIL with larvae in the 2 intervention and control communes, the results are summarized in Table 3.30: Table 7.

For Dien Phu commune- intervention: the Breteau index, the percentage of households with a larva, the percentage of IUDs with a larva in the intervention commune was still lower than before the intervention and lower than in the control commune (p = 0.006; 0.004 ; 0.002 <0.05). Sumilarv 2MR in a narrow field intervention reduced the larvae indicators: Breteau, percentage of houses with larvae, percentage of IUDs with larvae up to 3 months after release. Interview results showed that of the 6 experimental volunteers and 100 representatives of families participating in the 2MR sumilarv insecticide test, no one had any adverse reactions within 24 hours of the intervention. Total 100% of people commented that sumilarv 2MR was easy to use and agreed to use sumilarv 2MR insecticide in preventing dengue transmission mosquitoes at the rate of 100%. CHAPTER 4. DISCUSSIONS
