Malaria vectors and their behavior during the rising and falling seasons in the community of Santa Emilia

Two field trips were conducted during the months of April and October in the remote community of Santa Emilia, which is located 8 hours from the city of Nauta (2 hours from the city of Iquitos). Collections were carried out during the rising season in April and the falling season in October. Three nights of collection were conducted using the HLC method to observe intra-peri bite patterns during a 12-hour collection period. Additionally, during 2 nights, the barrier method was employed to assess vector feeding preferences. Ovary dissection was also performed to determine the age of the mosquitoes. It was found that bite indices were high during the rising month, while in the falling month, mosquito densities decreased considerably.
