Abstract: Mesocyelops guang xiensis (Sp. to be identified) compared with M. aspericornis(French) and M. darwini(Australia) for its potential biocontrol effect in laboratory. The much more. suitable temperatures range for its population multiply are between 25℃～35℃. After 72 hrs larvae of Aede aegypti, Culex quinquefasciatus and Anophles farauti will be suffered 82%～100% mortality. In the experimental cage, the copepod population increased exponentially in response to its abundant larval food source. Within six weeks, the mosquitoes larvae will completely controlled by the copepods, then, the adult mosquitoes will decreased to zero within eleven weeks. In the control cage, immature and adult mosquitoes rose to a point of equilibium, where their population sise were determi- ned by food levels and spatial limiting. The range of tolerabilities of salinity and pH are from 0～4‰, 6.0～10.5 respectively which make all Mesocyclops in a good condition as a biocontrol agent for mosquito larvae.
