斯氏按蚊感染约氏疟原虫后,饲以10％的蔗糖水加入适量之对氨苯甲酸(PABA)并增加一次血餐,可促进疟原虫在蚊体内之发育。表现为:卵囊数较单饲以10％蔗糖水的对照组高出近一倍,卵囊发育较快,在第七天测量卵囊平均直径大于对照组。在24℃左右子孢子于第八天开始进腺,较对照组提早一天。腺感染率在第14天实验组达82％,对照组则为63.5％。
After Anopheles stephensi infected Plasmodium yoelii, 10% sucrose water was added to the right amount of PABA and a blood meal was added to promote the development of Plasmodium in the mosquito. The results showed that the number of oocysts was nearly double that of the control group fed with 10% sucrose alone, the oocysts developed more rapidly, and the average diameter of oocysts measured on the seventh day was larger than that of the control group. Sporozoites began to enter the gonads at day 24 at about 24 ℃, one day earlier than the control group. Gland infection rates were 82% in the experimental group on day 14 and 63.5% in the control group.
