Adult Culicidae captured using a Nasci aspirator

In total, 110 adults Culicidae were captured, 73 males (66.36%) and 37 females (33.64%).Of this total, 99 were A. aegypti (90%), being 63 males (63.64%) and 36 females (36.36%), and 11 were C.quinquefasciatus (10%), being 10 males (90.90%) and one female (9.10%) ( Table 3). The total number of mosquitoes collected with the Nasci aspirator, as well as the percentage in each region, are shown in Table 3.

Note that only A. aegypti was collected in all five regions of Londrina. Analyzing the number of A. aegypti adults aspirated in each of the five regions of Londrina, it is possible to see that the largest number of mosquitoes was obtained in the West region, while the smallest number was obtained in the North region. The average values of A. aegypti obtained in each of the five regions, together with the respective standard deviation values are also shown in Table 3.

Considering the Kruskal-Walli’s test, there was a significant difference between the averages of aspirated A. aegypti adults, at a 5% significance level (p = 0.0221; H = 8.658). The Dunn test showed that the Central region differs from the South, North, and East regions, regarding the aspirated mosquito averages. Equally, a difference was observed between the average values obtained in the West and North regions ( Table 3).

In relation to the number of A. aegypti captured with a Nasci aspirator in each month of the sampling period, April was the only month where A. aegypti was not captured. On the other hand, the largest number of adults of this species (both males and females) was captured in May.
