A Study on the longevity of three anophelines species were carried out in Buleleng regency, Bali province. The objective of this study was to detectthe longevity of three anophelines species malaria vectors in Indonesia, i.e.: Anopheles aconitus, An. subpictus and An. sundaicus. Collections of natural specimen were done bye three methods: (1) man-biting-catches, (2) night resting catches around cattle shelters, and (3) morning indoor resting catches. All specimens collected were then brought and dissected in the laboratory for defining dilatations. The result shown that the oldest of An. aconitus found in Buleleng regency, Bali province, was with 7 dilatations, estimated as about 21 days old; the oldest An. subpictus with 9 dilatations, estimated as about 27 days old; while for An. sundacius was 8 dilatations, estimated as about 24 days old. The conclusion of this study shown that the oldest of An. aconitus reach 21 days, An. subpictus reach 27 days, and An. sundacius reach 24 days.
