Cyclical transmission of Plasmodium berghei (Coccidiida: plasmodiidae) by Anopheles omorii (Diptera: Culicidae).
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.
