“…This mosquito was believed as a main vector for W. bancrofti in the urban areas. 4,17,18 It can be explain that in these areas have potentially of filariasis transmission due to the positive results in microscopic examination and the mf density in the non-elephantiasis patient, It could be noted that these areas have potentialities of filariasis transmission due to the positive results of microscopic examination and the mf density in the non-elephantiasis patients. It is possible that there are quite high sufferers and vectors, although the findings in this study were low.…”

“…aegypti have not yet confirmed as a vector of filariasis in Central Java; however, a Ramadhani's study on periodicity of W. bancrofti microfilariae found that 14% of microfilariae were still circulating in the peripheral blood at 6 am. 4 On the other hand, in the morning the Aedes mosquito has started to increase in density. These two phenomena allow transmission of filariasis by Ae.…”

“…3 One of them happened in Pekalongan, and its periodicity is nocturnal. 4 Filariasis cases in Indonesia are still high. In Indonesia, in 2019 there were 10.758 cases of filariasis spread across 34 provinces; this report is higher than the previous year.…”

Background: The filariasis elimination program in Indonesia has been conducted, but new cases and some chronic cases are still often found. Objective: This study aims to determine levels of endemicity and to identify filarial worm species in filariasis cases and s and their surrounding communities by using microscopic examination, polymerase chain reaction (PCR), and to examine levels of infection in vectors mosquito by surgery and PCR. Also to to determine that Ae. aegypti can act as vector of filariasis. Methods: This study was conducted at 10 locations in Pekalongan Regency, Central Java Province, with a cross sectional design. Intravenous blood sampling was conducted on 102 respondents consisting of 10 elephantiasis patients and 92 non-elephantiasis patients at night, starting at 8 pm, then examined microscopically and PCR. Mosquitoes in this study were collected by using a human landing collection method for 12 hours from 6 pm to 6 am by volunteers. Artificial infection of microfilaria W. bancrofti was held against Cx. quinquefasciatus and Ae.aegypti from laboratory collection. Results: Results of this study found that there were 5.729 of mosquitos, consisting of 8 species, namely Culex quinquefasciatus, Culex vishnui, Culex tritaeniorhynchus, Aedes aegypti, Aedes albopictus, Anopheles subpictus, Anopheles vagus, and Armigeres kesseli. Microfilarial (mf) rate was 0.89%, and and the blood PCR showed infection rate of 3.92% and the blood PCR showed infection rate of 3.92%. No larva was found in female mosquito dissection. The PCR results showed that the infection rate was 9.10% in Ae. aegypty pool respectively. Artificial infection results was negative both dissecting microscopis and PCR. Conclusion: This study revealed that the locations were low of filariasis endemicity. The mf rate was less than 1%, and there was a moderate density to high density of microfilaria in the patients. The low level of infection rates in mosquito is suggested as an alert to its potential transmission.

“…The urban filariasis vector is Culex quinquefasciatus mosquito, while the rural includes Anopheles, Culex, and Aedes mosquitoes. 4 In Central Java, there were 439 chronic cases of filariasis in 2018 and it was ranked 6 th as the province with the highest number of filariasis cases in Indonesia. 1 Efforts to eliminate filariasis are in line with the strategy formulated by the World Health Organization, which is based on large-scale treatment activities to suppress the spread of the disease and reduce the disability impact caused by filariasis.…”

Nocturnal Activity of Aedes spp. in the Filariasis Endemic Area in Central Java

Program eliminasi filariasis belum menunjukkan hasil maksimal di Provinsi Jawa Tengah. Perubahan perilaku vektor nyamuk terutama waktu aktif menghisap darah sangat mempengaruhi penularan penyakit filariasis. Salah satu perubahan perilaku vektor tersebut adalah aktivitas nyamuk Aedes spp. yang aktif di pagi hari menjadi aktif di malam hari. Tujuan penelitian ini adalah untuk mendeskripsikan aktivitas nokturnal nyamuk Aedes spp. di daerah endemis filariasis di Jawa Tengah. Penelitian ini merupakan penelitian observasional dengan desain cross-sectional yang dilakukan di dua desa endemis filariasis yaitu Desa Tegal Dowo, Kecamatan Tirto, Kabupaten Pekalongan dan Desa Ujung-Ujung, Kecamatan Pabelan, Kabupaten Semarang. Penangkapan nyamuk dilakukan selama 2 malam di rumah penderita filariasis atau rumah di sekitar rumah kasus (Jarak ± 200 meter) dengan menggunakan teknik purposive sampling. Penangkapan nyamuk berlangsung pada pukul 18.00 - 24.00 WIB dengan jumlah penangkap nyamuk 3 orang di dalam dan 3 orang di luar rumah. Pengumpulan nyamuk dilakukan dengan metode Human Landing Collection (HLC) dan resting collection. Hasil penelitian menunjukkan peningkatan aktivitas nokturnal Aedes aegypti dan Aedes albopictus di daerah endemis filariasis di Jawa Tengah. Total nyamuk Aedes spp. yang ditemukan yaitu sebanyak 124 nyamuk, dengan 121 Ae. aegypti ditemukan di dalam rumah dan 2 nyamuk diluar rumah. Di dua wilayah penelitian ditemukan waktu aktif Ae. aegypti berada pada pukul 18.00-19.00 WIB. Hasil penelitian ini menunjukkan adanya aktivitas nokturnal dari Aedes spp. di wilayah endemis Filariasis di Provinsi Jawa Tengah

Background and Aim: Lymphatic filariasis, also known as elephantiasis, still remains a problem in Indonesia. The primary causative species of this disease are the filarial worms Wuchereria bancrofti and Brugia spp. This study was conducted to identify the diversity of species and behavior of mosquitoes and to determine the mosquitoes that could be potential vectors of filariasis. Materials and Methods: Mosquito samples derived from Hulu Sungai Utara (HSU) district in the 2017 multicenter study conducted in Indonesia were used in this cross-sectional study. The diversity of mosquito species was analyzed using the Shannon–Wiener diversity index. Mosquitoes were identified based on their species, and their DNA was isolated by polymerase chain reaction (PCR). Transcription-insulated isothermal PCR method was used to detect microfilariae/filaria larvae in the mosquitoes. Results: Biodiversity was found in 14 species of mosquitoes belonging to five genera. The maximum number of mosquitoes was recorded from the species Mansonia dives, Culex vishnui, Culex quinquefasciatus, and Mansonia uniformis. W. bancrofti infection was detected in M. uniformis at an infectivity rate of 0.3% (n=311). Conclusion: To the best of our knowledge, this is the first report of M. uniformis species as a vector of W. bancrofti in HSU district, Indonesia. More efficient and accurate studies are required to aid in the lymphatic filariasis elimination programs in this subregion.
