Adultrap® trap optimized for collecting vector mosquito eggs, larvae and adults

[Armadilha Adultrap® otimizada para coleta de ovos, larvas e adultos de mosquitos vetores]

ABSTRACT

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.
