title: Laboratory colonization and life cycle of Coquillettidia crassipes in Malaysia.
abstract: Methods are described for the laboratory colonization of Coquillettidia crassipes. The highest rate of insemination occurred in 60 x 60 x 120 cm cages and better insemination in laboratory adapted F15 generation. Embryonation and hatchability of eggs ranged from 69.6 to 97.9% and 63.3 to 94.3% respectively. Gravid females laid egg rafts on water in 500 ml breakers with small leaves of Salvinia for resting. Newly hatched larvae were set up in a basal medium of guinea pig dung and water or liver powder, yeast powder and water. Larvae attached to aquatic plants or 'Keaykolour' ruffia snow white paper. The cultures with paper gave better yields. At present 21 generations of Cq. crassipes have been reared in the laboratory.
