Table 2 Geographical locality, human population, annual parasite index (API) of P. vivax, remaining susceptible population (SH), prevalence of P. vivax in Ny. darlingi, and daily human biting rate per person (HBR) calculated using data of 216 h human landing catch (HLC) in the peridomestic environment of 36 houses in rural settlements of five municipalities in the Brazilian states of Acre, Amazonas and Rondônia

From: Vector competence, vectorial capacity of Nyssorhynchus darlingi and the basic reproduction number of Plasmodium vivax in agricultural settlements in the Amazonian Region of Brazil
