Information about colony fragments survival of the termite species Coptotermes curvignathus Holmgren in the laboratory is very limited. This study was conducted to determine colony fragments survival of the subterranean termite C. curvignathus Holmgren in laboratory maintenance. The test media used the Termitarium PSIH-IPB: 1999 as a glass vessel containing 4 kg of a mixture of sand and clay with 4 proportions and 4 different pH determined as treatments that would be studied for their effects on termite survival. The results showed that the proportion of the sand:clay mixture affected the survival and feeding preferences of the subterranean termite C. curvignathus Holmgren. The highest percentage of termites that survived was found in the termitarium containing a mixture of sand:clay 50:50. The highest percentage of bait wood weight loss occurred in the test media containing a mixture of sand: clay 50:50. The weight loss of bait wood is directly proportional to the termites survival.

Informasi tentang daya tahan hidup koloni atau fragmen koloni spesies rayap Coptotermes curvignathus Holmgren di laboratorium sangat terbatas. Penelitian ini dilakukan untuk mengetahui daya tahan hidup fragmen koloni rayap tanah C. curvignathus Holmgren dalam pemeliharaan di laboratorium. Media pengujian menggunakan Termitarium PSIH-IPB: 1999 berupa bejana gelas yang berisi 4 kg campuran pasir dan liat dengan 4 proporsi serta 4 pH yang berbeda ditentukan sebagai perlakuan yang akan ditelaah pengaruhnya terhadap daya hidup rayap. Hasil penelitian menunjukkan bahwa proporsi campuran pasir:liat berpengaruh terhadap daya hidup dan preferensi makan rayap tanah C. curvignathus Holmgren. Persentase rayap yang bertahan hidup paling tinggi terdapat pada termitarium berisi campuran pasir:liat 50:50. Persentase kehilangan berat kayu umpan tertinggi terjadi pada media pengujian berisi campuran pasir:liat 50:50. Kehilangan berat kayu umpan berbanding lurus dengan daya tahan hidup rayap.
