ield surveys of ectoparasites fauna on small mammals (Rodentia and Scandentia) were conducted since 2008 until 2019 in 12 localities of Sarawak, Malaysia (Borneo). The objectives of these field surveys are to obtain checklist on the distribution of ectoparasites and their hosts (rodents and scandents) in Sarawak, and to determine the ectoparasites that are of known public health importance. Throughout these surveys, seven types of habitat had been recorded from 12 localities of study sites, namely lowland dipterocarp forest, mixed dipterocarp forest, hill dipterocarp forest, riverine forest, limestone forest, secondary forest, and urban area. A total of 50 to 100 cage traps were used to traps hosts for five to six consecutive days per site and ectoparasites were extracted from each host caught using fine comb and forceps. Identification of ectoparasites was based on morphology from available taxonomic keys and published taxonomic drawings. A total of 148 animals comprising 22 species of rodents and scadents were caught and screened for ectoparasites. Of these hosts, 46 species of ectoparasites were identified from a total of 2463 individuals collected. Among the ectoparasites found, six species collected are of known medical importance namely Ixodes granulatus (ticks) Laelaps nuttalli (mesostigmatid mites), Leptotrombidium deliense (trombiculid mites), Sarcoptes scabiei (astigmatid mites), Polypax spinulosa, and Hoplopleura dissicula (lice). Further surveys are recommended for more comprehensive inventory of ectoparasites in different locations and habitats that can build up extensive wealth of information on various aspects such as host-parasite relationship, biology and ecology.

ABSTRAK

Tinjauan lapangan fauna ektoparasit pada mamalia kecil (Rodentia dan Scandentia) telah dijalankan sejak dari tahun 2008 hingga 2019 di 12 lokasi di Sarawak, Malaysia (Borneo). Objektif tinjauan lapangan ini adalah untuk mendapatkan senarai semak awal mengenai taburan ektoparasit dan perumahnya (Rodent dan Scandents) di Sarawak dan untuk mengetahui ektoparasit yang penting untuk kesihatan awam. Sepanjang tinjauan ini, tujuh jenis habitat telah dicatatkan dari 12 lokasi kawasan kajian iaitu hutan dipterocarp dataran rendah, hutan dipterocarp campuran, hutan dipterocarp bukit, hutan sungai, hutan batu kapur, hutan sekunder, dan kawasan urban. Sebanyak 50 hingga 100 perangkap telah digunakan untuk memerangkap perumah selama lima hingga enam hari berturut-turut dan ektoparasit diekstrak dari setiap perumah yang ditangkap menggunakan sikat halus dan forsep. Pengenalpastian ektoparasit adalah berdasarkan morfologi dari kunci yang ada, gambar dan rujukan taksonomi yang telah diterbitkan. Sejumlah 148 haiwan yang terdiri daripada 22 spesies rodents dan scadents telah ditangkap dan disaring untuk kehadiran ektoparasit. Daripada haiwan perumah ini, 46 spesies ektoparasit telah dikenal pasti daripada jumlah keseluruhan 2,463 individu yang telah dikumpulkan. Antara ektoparasit yang dijumpai, lima spesies yang dikumpulkan mempunyai kepentingan perubatan iaitu Ixodes granulatus (sengkenit), Laelaps nuttalli (hama mesostigmatid), Leptotrombidium deliense (tungau), Sarcoptes scabiei (hama astigmatid), Polypax spinulosa dan Hoplopleura disicula (kutu). Tinjauan lebih lanjut adalah disarankan untuk persediaan kajian ektoparasit yang lebih komprehensif di lokasi dan habitat yang berbeza yang supaya dapat mengumpulkan banyak maklumat mengenai pelbagai aspek seperti hubungan parasit-perumah, biologi dan ekologi.
