Sporozoites of plasmodium sp. in anopheles mangyanus and oocysts in A. kochi

Dissections of anopheles mosquitoes in Tabla Valley, Cauayan, Occidental Negros (Philippines), conducted to determine the existence of malaria vectors other than A. minimus flavirostris in the Philippines, showed the following results: 1) Oocysts and sporozoites were found in A. mangyanus2) Infected guts and glands in A. minimus flavirostris were also demonstrated3) Oocysts were found in A. kochiAlthough it was not possible to ascertain if the sporozoites and oocysts found were those of human, avian or simian malaria, there is a strong presumption to incriminate A. mangyanus as a vector of human malaria in the Philippines.
