Abstract: The study was carried out from 1980 to 1985 in Daisan township with a population of 26 000 in Huang-huai Plain, an endemic area of vivax malaria transmitted by An. sinensis. Since the development of irrigation system and water conservancy and the expansion of rice fields in the fifties have brought forth an increase in human-mosquito contact and the vectorial capacity in the Plain, the number of malaria cases increased significantly and the single measure of mass drug administration (MDA) could not bring about the desired effect of malaria control. Considering conjointly the bionomical behaviour of An. sinensis, the sole vector for malaria transmission, the human behaviour of villagers and local conditions, an integrated approach was under trial and assessed parasitologically, serologically, and entomologically. The approach included motivating the villagers to sleep indoors and to use bed-nets, improving ventilation in houses by installing back windows and reducing human infection source by MDA and case treatment.The annual parasite incidence (API) of malaria decreased from 181‰ in 1980 to 0.45‰ in 1985. Although MDA was stopped in 1983-1985, malaria incidence continued to decrease. It has been shown that the reduction of human-mosquito contact could bring about the decrease of the man-biting rate, the human blood index and the vectorial capacity of An. sinensis and the transmission rate of malaria. It is a successful field trial of the integrated approach for malaria control in the area concerned.
