“…These include Adultrap ® [34] and ovitraps [35,36]. Adultrap ® is evenly distributed throughout the urban territory of the municipality, being present in one in 25 houses, totalling 3476 active traps [37]. These traps are verified periodically by the Zoonoses Control Center of Foz do Iguaçu (CCZ-Foz).…”

objective In Brazil, the most common method of controlling outbreaks of arbovirus is by the use of chemical sprays, which kill the insect vector, Aedes aegypti. The main objective of this study was to evaluate the resistance of Ae. aegypti to the insecticide, malathion, in situ. The location of this study was the municipality of Foz do Iguaçu, in the state of Paraná, Brazil. methods Ultra-low-volume (ULV) fogging equipment was used, by vehicle, to apply the insecticide in situ, and mosquito populations after treatment were compared with those of control areas. The resistance of strains collected from the municipality was compared to the Rockefeller strain under laboratory conditions. results We found 220 adult female specimens and 7423 eggs of Ae. aegypti in the areas subjected to UBV treatment, whereas 245 adult females and 10 557 eggs were found in the control areas. The UBV treatment area showed no significant difference compared to the control area, for all the indices. Mortality of the Rockefeller colony varied more quickly when there were slight variations in malathion concentration than the Foz do Iguaçu population. keywords Arboviruses, entomological surveillance, chemical control, ultra-low volume (ULV), Foz do Iguaçu Sustainable Development Goals (SDGs): SDG 3 (good health and well-being), SDG 15 (life on land), SDG 17 (partnerships for the goals)

The productivity of the Adultrap® trap was compared to that of modified adultrap traps. Two structural changes were tested, a cover was placed at the entrance of the trap at two different heights. A comparison was also made with traps containing hydrogel to replace the water in the reservoir. The positivity rates of all the trap types were calculated and compared. The hydrogel models were more productive because they collected eggs, larvae, and adults. The trap that removed the protective screen and replaced the water with the hydrogel was 18.5 times larger than the original trap (p = 0.001). There was an increase in the productivity for the total collection of mosquitoes. The collection of eggs, larvae, and adults can contribute to the construction of more robust infestation indices. In addition, it allows for the collection of live specimens and the development of studies.
