| dc.description.abstract | Malaria’s cases have been reported to occur annually in Wongsorejo district of
Banyuwangi, East Java since 2002. However, there is a significant decrease of malaria cases
during these last years, which might be related to the malaria vector species shifting composition.
The objective of this research was to observe some important bionomic characteristics of malaria
vector Anopheles in this area from 2015 until 2020 which include species identification, blood
feeding behaviour and biting preference of vector. The data collection i.e. determination of
Anopheles diversity and behaviour was conducted monthly for 3-6 months annually from 2015
– 2018. In 2019-2020 we sampled irregularly to see the trend. The results showed that there were
species shifting of Anopheles vectors in this area. The proportion of Anopheles (An.) sundaicus
and An. subpictus, which were previously reported until 2015 as the main Anopheles species in
this area, significantly decreased in 2016 - 2018. An. indefinitus & An. vagus was becoming the
majority of Anopheles species. During 2019-2020, An. vagus became the main species identified
in the sampling area. The predominant species of An. vagus and An. indefinitus has exophagic
and zoophilic preference behaviour. Furthermore, An. indefinitus has not previously been
identified as a vector for malaria, compared to An. sundaius, and An. subpictus which are well
known as an important primary malaria vector on Java Island, Indonesia. | en_US |
