Mosquito species in water-filled bamboo stumps were compared with those eme
rged from dormant eggs in dry stumps. Tripteroides spp. was more abundant t
han Aedes (Stegomyia) spp. (mainly annandalei and albopictus) in water-fill
ed stumps, whereas the latter was more abundant than the former in dry stum
ps. During 5 days after inundation, Aedes (Stegomyia) spp. developed faster
than Tripteroides spp. Density of Tripteroides spp. was high in narrow and
deep stumps. Both taxa of mosquitoes were at low densities in water-filled
stumps with large detritivores (Tipulidae and Oligochaeta).
