Experimental transmission of Plasmodium yoelii nigeriensis to mouse (Balb/C) by bite of Anopheles omorii was conducted. Infected mice were exposed to a laboratory colony of An. omorii, TM-86 strain. After blood-sucking, the mosquitoes were kept in a nylon mesh cage with a piece of cotton soaked with a 3% sugar solution at 24±1℃ and 70% RH for a photoperiod of 15L : 9D including 1hr of controlled dawn and dusk. Four days after bloodsucking, a considerable amount of oocyst was formed on the wall of the mid-gut of several mosquitoes. Seven days after blood-sucking, formation of sporozoites in the oocyst was detected. From the 10th day sporozoites were observed in the salivary glands of the mosquitoes. From 11 to 15 days after blood-sucking, 1 to 3 normal mice were exposed to the infected mosquitoes. A total of 54 mice were tested, and 44.4% of them were infected with Pl. yoelii by bite of the mosquitoes. It was found that An. omorii was susceptible to Pl. yoelli and had the capacity for its transmission.
