Abstract: A.kunmingensis was described by Dong et Wang in 1985.During the period 1986-1988,a series of studies were carried out to clarify its geographical distribution,ecology and habits,role in malaria transmission as well as measuree mosquitoes of which it occurred to the north of 24°N latitude with an elevation above 1600 m.Rice padddies,ponds and ditches were the chief habitats of larvae.Resting places of imagoes were frequently inside houses,amounting to 81.1% of the total of house-resting Anopheles.In November to the first tenday period of January every year,and no more occurred below 1600 m.By the use of precipitin tests,the origin of ingested blood in the stomach of houseresting A.kunmingensis was 75.6% indicative of human origin.The seasonal fluctuation of the density of the species was in agreement with the malaria incidence curve of the locality surveyed.This species was sensitive to P.vivax,natural sporozoite rate of 0.104%.From the above-mentioned studies the writers come to the conclusion that A.kunmingensis is an important vector in 1600 m.Conventional residual spray of insecticides is effective in control of this vector.
