Diversity and Activities of Mosquito in Yogyakarta Special Region Province, Indonesia, a Non Filariasis Endemic Area

According to data from the Ministry of Health of the Republic of Indonesia in 2018, there were 37 cases of Elephantiasis in Yogyakarta, even though Yogyakarta is not an endemic area of filariasis. This preliminary study was carried out to evaluate the diversity of species, relative abundance, frequency and dominance of mosquitoes in Yogyakarta and to determine the role of mosquitoes as a vector of filariasis. A cross-sectional study was used involving 3 hamlets with elephantiasis cases found in April 2019 in Yogyakarta. Mosquitoes around the house inhabited by the patient with elephantiasis were collected for 12 hours starting from 6:00 p.m. until 6:00 a.m. Mosquitoes were dissected under a dissection microscope and the presence of filaria larvae was observed. A total of 9 mosquitoes species were found. They were Culex vishnui, Culex tritaenorhynchus, Armigeres kesseli, Aedes albopictus, Culex quinquefasciatus, Culex bitaenorhynchus, Anopheles vagus, Anopheles subpictus, Aedes aegypti. The highest diversity, frequency, and dominance was Culex vishnui, while the lowest was Culex quinquefasciatus. There was no filarial larva found during the study.
