3.1.1. Species composition of Anopheles and vector distribution in the Central-Highlands A total of 18 Anopheles species were found in the Central-Highlands region, including 16 species from the Central and 14 species from the Highlands. Two primary malaria vectors An. dirus and An. minimus and three secondary vectors An. aconitus, An. jeyporiensis and An. Maculatus were collected. Table 3.2.
