Abstract

Anopheles omorii, a tree-hole breeding anopheline collected in Japan, transmitted a rodent malaria, Plasmodium berghei ANKA strain, in the laboratory. Mice with 0.2-15% parasitemia, 0.01-1.5% gametocytemia, and 0.001-0.5% exflagellations were used as infective hosts. Oocyst numbers ranged from 2 to 171 (mean 44) on the midgut 8-16 d after the blood meal. Several to hundreds of sporozoites were detected in the salivary glands 14 d after feeding. The mosquitoes were infective to mice from 13 to 40 d after feeding. An. omorii occurs naturally at temperatures less than 25 degrees C and therefore is a suitable laboratory vector for the cyclic transmission of P. berghei, a malaria parasite that completes sporogony at 18-21 degrees C.

摘要

大劣按蚊日本株，一种在日本采集的树洞孳生的按蚊，在实验室中传播了一种啮齿动物疟疾——伯氏疟原虫ANKA株。具有0.2%-15%的寄生虫血症、0.01%-1.5%的配子体血症以及0.001%-0.5%的动合子形成率的小鼠被用作感染宿主。在血餐后8-16天，中肠上的卵囊数量在2至171个之间（平均44个）。喂食后14天，在唾液腺中检测到数个至数百个孢子体。这些蚊子在喂食后13至40天对小鼠具有感染性。大劣按蚊日本株自然发生于温度低于25摄氏度的环境中，因此是伯氏疟原虫循环传播的合适实验室媒介，伯氏疟原虫是一种在18-21摄氏度完成孢子生殖的疟原虫。
