摘　　要：用食蟹猴疟原虫B株接种恒河猴后,在最佳感染时机血餐,第7d胃感染率,大劣按蚊平均为94.9％(74/78),斯氏按蚊平均为94.6％(70/74)。第12d涎腺感染率,大劣按蚊平均为93.9％(62/66),斯氏按蚊平均为92.2％(59/64),两者的胃和涎腺感染率无显著性差异。卵囊均数,大劣按蚊为124.2个,斯氏按蚊为47.6个,前者为后者的2.6倍。在欠佳感染时机血餐,大劣按蚊的胃和涎腺感染率均高于斯氏按蚊,大劣按蚊的卵囊均数为斯氏按蚊的3倍余。This paper reports on the comparative susceptibility of A. dirus (Hainan strain) and A. stephensi (Hor strain) to the B strain of P. cynomolgi in paired feeding experi-ments. In the most susceptible infective period, the infection rate in midgut and salivary gland of the two species was over 90 %, the difference is not statistically significant.In relatively infective period, three experiments were performed, the infection rate in midgut of A. dirus was 24.4-60.4% with an average of 46.5% (53/114), and that of A. stephensi was 11.5-21.1% with an average of 14.2% (16/113). Statistically, experiment I showed no significant difference, the difference in experiment n was highly significant (P<0.01), and that in experiment JI was significant (P<0.05). The number of oocysts in A. dirus was three times over that in A. stephensi. The infection rate of salivary gland in A. dirus was 18.2-55.0% with an average of 30.6% (19/62) and that of A. stephensi was 6.7-14.3% with an average of 9.5% (6/63). Statistically, only one of the three experiments showed significant difference (P<0.01). The result suggests that the susceptibility of A. dirus is higher than that of A. stephensi to the B strain of Plasmodium cynomolgi.
