NON-CALLIPHORIDAE-NECROPHAGOUS-DIPTERA SUCCESSION ON PIG CARCASSES IN MANADO, INDONESIA

Abstract

Abstrak. Penelitian mengenai suksesi Diptera nekrofagus non-Calliphoridae dilakukan di Manado, Indonesia pada tahun 2012. Tiga ekor bangkai babi domestik (berat badan 21-23 kg) dimatikan dengan tiga cara yang berbeda (dosis letal potasium sianida per oral, pukulan benda tumpul pada area osipital, dan tikaman benda tajam). Penelitian dilakukan selama 15 hari. Suhu udara ambien dan kelembaban, serta data suhu dari Badan Meteorologi Klimatologi dan Geofisika (BMKG) Stasiun Klimatologi Kayuwatu. Babi yang dimatikan dengan potasium sianida memperlihatkan perlangsungan dekomposisi yang lebih panjang (10 hari) dibandingkan dengan lainnya (delapan hari). Simpulan: Terdapat empat famili dan dua spesies Diptera nekrofagus non-Calliphoridae yang mengunjungi bangkai hewan coba: Sarcophagidae, Piophilidae, Ophyra, Phoridae, Musca domestica, dan Hermetia illucens. Sarcophagidae dan Ophyra telah ditemukan sejak hari ke-1. Dari keenam jenis serangga non-Calliphoridae yang berkunjung, hanya empat jenis yang berkolonisasi pada bangkai hewan coba, yaitu: Ophyra, Phoridae, Musca domestica, and Hermetia illucens.

Abstract. A study was conducted on Non-Calliphoridae-Necrophagous-Diptera succession on pig carcasses in Manado, Indonesia, in the year 2012. Three domestic pig carcasses (weighing 21-23 kg) were killed by using three different manners (a lethal oral dose of potassium cyanide, a blow with a blunt material, and a stabbing with a sharp material). This study was conducted for 15 days. Ambient air temperatures and humidity, and temperature data of the Climatology Station, Kayuwatu were recorded. The pig killed with potassium cyanide showed a longer decomposition duration (10 days) than the others (eight days). Conclusion: there were four families and two species of Non-Calliphoridae-Necrophagous Diptera visited the carcasses: Sarcophagidae, Piophilidae, Ophyra, Phoridae, Musca domestica, and Hermetia illucens. The first visitors (day 1) were Sarcophagidae and Ophyra. From the six visitors, there were only four that colonized on the carcasses: Ophyra, Phoridae, Musca domestica, and Hermetia illucens.
