4.1.1. Species composition of Anopheles in the Central-Highlands There were 16 Anopheles species found in the Central region and 14 Anopheles species collected in the Highlands. Both the main malaria vectors An. dirus and An. Minimus were present in the two regions. However, An. dirus outnumbered An. minimus in the Central region, while they were equal in same in the Highlands. In addition, secondary vectors An. aconitus, An. jeyporiensis and An. maculatus were also detected in the study sites. This result is similar to the result of a species composition survey in hydropower and irrigation areas in Gia Lai province from 2014 to 2016, including 18 species of Anopheles (Se San hydropower plant: 17 species; Krong Pa hydropower plant: 13 species). Five main and secondary vectors and members of Minimus (An. harisoni) were found. In Ia Khai commune (belonging to Se San 3A and 4 hydropower plants), there were 14 species collected in the forest, 16 species collected in the forest fringe, 11 species found in the residential area (village). In Ia Kreng commune (belonging to Se San 3 and Yaly hydropower plants), there were 10 species found in the forest, 11 species in the forest fringe, and 10 species in villages. In Chu Gu commune (belonging to Krong Pa hydropower and irrigation plant), 9 species were collected in the forest, 10 species in the forest fringe, and 8 species in the village. Ia Mlah commune (belonging to Krong Pa hydropower and irrigation plant) had 6 species in the forest, 9 species in the forest fringe, and 9 species in the village [40].
