Abstract: Rearing experiments of Cx. tritaeniorhynchus Giles immatures were conducted under different temperature and densities to ascertain the developmental period and the mortality, which are parameters required to estimate the survivorship of natural populations. Linear relationship was confirmed between the rearing temperature and the developmental velocity, and the developmental zero was estimated between 11 and 15C. No instar specific or temperature dependent mortality was observed. The density effect was represented by the prolongation of immature period and by the increase of mortality. Higher mortality was probably due to longer immature period. The observed density effects might be caused by competition for food in old instar larvae.
