A Study on Laboratory Rearing of Anopheles dirus / 第三军医大学学报

ABSTRACT

Anopheles dims Peyton et Harrison, 1979 is an important malaria vector in Southeast Asia and China particularly in forested hilly zones. To establisha a laboratory mating colony for this mosquito is one of the subjects to be solved urgently in malaria research.This paper is to report our experience on breeding this mosquito. Ecological environment is created to simulate the natural conditions. The room-temperature of the insectary is 25?-28℃ and its relative humidity is around 80%.Mosquitoes are kept in cages with the si2e of 50 ? 50 ? 100cm. The larvae are fed with a mixture of de-fatted pig liver powder and yeast with a ratio of 13. The adults are fed with a mixture syrup containing 4% of orange juice, 10% of sucrose and other materials. The insectary is illuminated with a 3o w fluorescent light in the day time and a 15 w blue light in the night continuously to induce mating.The mating rate of the fourteenth generation reached 68% and the descendants bred can be used in research work now.
