ABSTRACT

In a forensic acarology study, conducted in a secondary forest of Forensic Science Simulation Site, Universiti Kebangsaan Malaysia (UKM) in Bangi, Selangor, six carcasses consisted of three monkeys and three rabbits were placed individually in steel enclosures and observed for 35 days. The carcasses, the soil beneath them and pitfall traps were checked daily for insects and mites. A species of mesostigmatid mite, Macrocheles scutatiformis was discovered and this is a first time reported in Malaysia. There are about 94.0% of Macrocheles present inside the cages of the monkey and rabbit carcasses. Most mites in this study were collected from soil beneath the carcasses, on a dung beetle and a Chrysomya rufifacies larva. Our findings showed that M. scutatiformis have a potential role in forensic investigation involving dead animals perhaps corpses especially during the dry stage of decomposition.

ABSTRAK

Dalam kajian forensik akarologi yang dijalankan di hutan tropika sekunder di Tapak Simulasi Sains Forensik, Universiti Kebangsaan Malaysia (UKM) Bangi, Selangor, sebanyak enam bangkai haiwan terdiri daripada tiga monyet dan tiga arnab diletakkan secara individu di dalam sangkar dawai dan diperhatikan selama 35 hari. Pemeriksaan serangga dan tungau dilakukan setiap hari pada badan bangkai, tanah di bahagian bawah badan bangkai serta perangkap jatuhan. Spesies tungau Mesostigmata iaitu Macrocheles scutatiformis ditemui dan dilaporkan buat pertama kalinya di Malaysia. Sebanyak 94.0% Macrocheles ditemui pada sangkar bangkai monyet dan arnab. Kebanyakan tungau ini dikutip pada tanah di bawah badan bangkai, pada kumbang dan juga pada larva Chrysomya rufifacies. Hasil kajian ini menunjukkan bahawa M. scutatiformis berpotensi dalam penyiasatan forensik melibatkan haiwan mati dan mungkin juga mayat manusia terutama ketika pereputan peringkat kering. Secara keseluruhan, hasil daripada kajian ini dapat membantu dalam penentuan selang masa pasca kematian, sekiranya spesies ini ditemui maka dapat disimpulkan bahawa bangkai atau mayat tersebut telah pun mencapai peringkat terakhir pereputan iaitu peringkat kering.
